I am having some problems with my phone camera (I am using Sony Xperia Z1 Compact) because the camera is always on Landscape mode when I launch it via the intent and therefore the photo is rotated when taken in portrait mode. This issue doesn't exist on Nexus 5. How can I solve it ? The exif returns always 0 because it's locked on landscape

Google Places autocomplete Android - Not working

Toolbar bug with method setTitle
I am using this two methods in my toolbar:
toolbar.setTitleTextColor(getResources().getColor(R.color.ColorPrimary));
getSupportActionBar().setTitle("title");
The reason for using getSupportActionBar is because toolbar.setTitle("title"); is not working.
This is a bug?
Android Studio combine 2 .aar into one
I have an Android Studio library project which depends on another library project.
The top project depends on code and resources from the second library project.
When using just the top library-project .aar in a client app, the resources from the second library project are not found.
So do we have to always use 2 .aar files instead of one in such a situation?

Test events were not received - Android Studio
I have no idea how to test and I was following a tutorial.I am trying to run:
package name.company.sunshine.app.data;
import android.test.AndroidTestCase;
public class TestPractice extends AndroidTestCase {
/*
This gets run before every test.
*/
@Override
protected void setUp() throws Exception {
super.setUp();
}
public void testThatDemonstratesAssertions() throws Throwable {
int a = 5;
int b = 3;
int c = 5;
int d = 10;
assertEquals("X should be equal", a, c);
assertTrue("Y should be true", d > a);
assertFalse("Z should be false", a == b);
if (b > d) {
fail("XX should never happen");
}
}
@Override
protected void tearDown() throws Exception {
super.tearDown();
}
}
but I get somewhere in the bottom left corner, in the console Test events were not received. What am I doing wrong ? Should I run something else ?
GCC fails with no message when using precompiled headers
I am trying to use precompiled headers in my rather large android NDK project. The precompiled header builds correctly, and I get the gch file that I can see is being used when I compile the source file. However, the "make" command fails with Error 1, but GCC doesn't tell me why it failed:
../Makefile:##: recipe for target '...' failed
make[1]: *** [...] Error 1
make[1]: Leaving directory
I have also found that rearranging the headers such that my precompiled header is smaller (around ~128MB) it works. The original size of my pch was ~173MB. I know for VS, there is a /Zm option that allows you to change the size limit of a precompiled header, but I can't find such an option for GCC, nor can I find any indication that such a limit exists for GCC.
Does anyone have any ideas as to why my build will fail and any ideas on how I can work around it?
Thanks in advance.
EDIT:
Some clarifications:
1) The code DOES compile if I don't use PCH, so it's not like I'm missing libraries or files or anything like that.
2) I DO get GCC error messages when the compilation fails normally. It's only this one case where I don't see any.
Toast "Press back again to close" gives error when pressing back too often
My goal:
When a visitor goes back to the first page of my app, a toast appears to let the visitor know that he can press the back button again within 3 seconds to close the Android app.
Specific problem:
When you went back to the first page and the toast appears, the code works fine when you press back only once but when the toast appears and you press back more than one time, the following error message appears: "(appname) has stopped".
Does anyone know what causes this error message and how I can solve this?
MainActivity.java file:
// Open previous opened link from history on webview when back button pressed
private Boolean exit = false;
@Override
// Detect when the back button is pressed
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
}
else {
if (exit)
this.finish();
else {
Toast.makeText(this, "Press again to exit.",
Toast.LENGTH_SHORT).show();
exit = true;
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
exit = false;
}
}, 3 * 1000);
}
}
}

Google Play Store - Top New Games List
We published our first mobile game 5 days ago and it has almost 10 000 downloads so far and 4.9 rating. I am curious why the game is not presented in top new apps chart while there are many games in this chart with fewer downloads and lower rating.
Is this connected with the fact that the game was released only 5 days ago?
One document about that which I found is:
but the only accurate point here is that the game has to be less than 30 days old in order to get to top new games chart.
inflate view returns the old inflated result
I try to inflate a layout multiple times to be inserted inside another layout. Here is the code:
View oldView = null;
for (ProfileServiceCategory.ProfileService service : profileServiceCategory.getServices()) {
View view = LayoutInflater.from(context)
.inflate(R.layout.profile_service_list_item, viewHolder.rootView);
if(oldView == view) {
Log.d("test", "Error");
}
oldView = view;
TextView serviceName = (TextView) view.findViewById(R.id.profile_services_name);
serviceName.setText(service.getServiceValue());
}
The problem that I'm facing is the view variable that is being returned by inflate method is always the first inflated view. To be clear I added a Log.d , if everything worked as expected it should have been never called but it does hit.
I checked the view hierarchy and I can conform that new views in fact has been added to rootView but the reference that I get is for older view.
the grid should display at least two columns , according to screen size can display more
I have GridView, the grid should display at least two columns , according to screen size can display more.
<GridView
android:id="@+id/fragment_grid_gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="300dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="2"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
I don't know, how to do this.

Could you help me solve this issue please?
Preview ViewSwitcher in AndroidStudio
Is there an easy way to switch between the displayed view in a ViewSwitcher in the Android Studio preview, or is the only way to swap out the XML for the sub-views one at a time?
Android AudioFlinger Error: No More Overflow Buffers when playing video
I am trying to play a series of videos back-to-back in a never ending loop. For some reason, after the app has been running for several hours, my videos begin to stutter and this error shows up repeatedly in the logcat:
W/AudioFlinger( 6310): OutputTrack::write() 0xb36e8008 thread 0xb6ffebc8 no more overflow buffers
What exactly does this mean and how can I prevent this from occurring. I would like the app to be able to run indefinitely without the video issues popping up.
Calling a method in a fragment in a FragmentStatePagerAdapter from the activity that created it
I have an activity that has a navigation drawer and a Fragment state adapter. When ever I click something in the navigation drawer I am passing that info to the mainactivity via a interface.And then I am passing that data to the main fragment which is in Fragmentstateadapter. The problem is when ever the screen rotates I get a null pointer exception for the main fragment.`
public class MainActivity extends ActionBarActivity implements RightDrawerRecyclerAdapter.Filters,
LeftDrawerFragment.MenuSection,CommonAsyncTask.ServerData {
private static final String TAG = MainActivity.class.getSimpleName();
public MainFragment mMainFragment;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager pager = (ViewPager) findViewById(R.id.pager);
ScreenSlidePagerAdapter pagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
pager.setAdapter(pagerAdapter);
}
@Override
public void getMenuSelection(int selection) {
Log.d(TAG,"getMenuSelection->"+selection);
mMainFragment.getMenuSelection(selection);
}
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
Log.d(TAG, "in screenslide");
}
@Override
public Fragment getItem(int position) {
if (position == 0) {
Log.d(TAG, "in returning MainFragment");
mMainFragment=new MainFragment();
return mMainFragment;
} else {
return new MapViewFragment();
}
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
if (position == 0) {
return "List";
} else {
return "Map";
}
}
}}
So getMenuSelection is the method from the interface in navigation drawer. Then I have a method with the same name in my main fragment in MainFragment.So when ever I select something in the navigation drawer I can change contents in the main fragment but when ever I turn my screen a new instance of MainFragment is getting created and getItem(int position) is not getting trigged so my MainFragment object is null and now I cant pass data from my navigation drawer to main fragment.I tried making MainFragment object as static and that created problems in my MainFragment class.
So how can I get back the same MainFragment object even when the screen is turned. Or is there any better way to pass data between navigation drawer fragment and a fragment in FragmentState adapter

Intro animation for android app
I want to add an introduction "animation" to my application (which has a Navigation Drawer) to "teach" people how to use it (basically how to open the drawer, close it etc)
How can I do it? I want it to be interactive with the app itself: at the beginning I want it to show a "hand" pulling the navdrawer and then it waits until the drawer has been opened, then it performs other stuff. I have seen it in some applications but I don't know what to look for achieve it.
I'll appreciate any kind of help, thanks

How to implement custom CardScrollView on Google Glass?
I try'd to use a CardScrollView instead of a single View.I can set cards(with custom layouts) successfully with my code.I need to change the values of my TextFields when a new Message arrived from my LocalBroadcastReceiver. Do you have some idea how/where I can solve it?
Here are some code snippets from my project.
This is the onCreate method in the activity that the CardScrollView implements.
private List<Integer> cards;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
createCards();
xDataScrollView = new CardScrollView(this);
xDataScrollView.setAdapter(new XDataCardScrollAdapter(cards, getLayoutInflater()));
xDataScrollView.activate();
setContentView(xDataScrollView);
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver, new IntentFilter("newMqttData"));
...
}
With the following createCards() Method
public void createCards() {
cards = new ArrayList<Integer>();
cards.add(R.layout.x_general);
cards.add(R.layout.x_temperatures);
}
And this CardScrollAdapter.
public class XDataCardScrollAdapter extends CardScrollAdapter{
private List<Integer> cards;
private LayoutInflater inflater;
private SingletonData data;
public XDataCardScrollAdapter(List<Integer> cards, LayoutInflater inflater){
this.cards = cards;
this.inflater = inflater;
this.data = SingletonData.getInstance();
}
@Override
public int getCount() {
return cards.size();
}
@Override
public Object getItem(int i) {
return cards.get(i);
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
return inflater.inflate(cards.get(i),viewGroup,false);
}
@Override
public int getPosition(Object o) {
return cards.indexOf(o);
}
}
Edit I was able to have some values in both defined cards at the startup of the activity but I'm still unsure how to update the data from my broadcast receiver. Here my modified getView method in XDataCardScrollAdapter. Even dont know if that is an acceptable solution or that something can go wrong here.
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
if(view == null){
view = inflater.inflate(cards.get(i), viewGroup);
}
if(i == 0){
TextView textView_speed = (TextView) view.findViewById(R.id.textView_speed);
textView_speed.setText(data.getSpeed());
... more values here
}else if(i==1){
TextView textView_temperatureValue = (TextView) view.findViewById(R.id.textView_temperatureValue);
textView_temperatureValue.setText(data.getTemperature());
...more values here
}
return view;
}

Android - new algorithm on wifi channel scanning
I have two questions:
- I want to develop a new wireless channel scan algorithm on android devices. Android supports function this is
getScanResults()which inWifiManagerclass. Also how may I changegetScanResults()function. I want to use with passive channel scanning algorithm and unicast channal scanning algorithm - I want develop a android application sending Probe Request and listen probe response.
diffrence between Appcompact activity and actionbar activity
In Android What is the main difference between extending a class from AppCompatActivity and ActionBarActivity? How do these classes differ?
Android studio multithreaded downloader
I am trying to make a multuthreaded downloader which can download a given file by breaking it into 3 chunks and downloading in parallel. The issue is, when I run the code, it seems that Thread 2 doesnt start unless Thread 1 finishes and Thread 1 doesnt start until Thread 0 finishes. I want all the threads to run simultaneously, following is my code:
protected Void doInBackground(Void... params){
try{
if(ThreadName == "1")
{
Log.d("DownloaderSleeper", "putting thread 1 to sleep");
Thread.sleep(3000);
}
URL url = new URL(UrlString);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("Range", "bytes=" + StartingByte.toString() + "-" + EndingByte.toString());
connection.connect();
//File f = new File(TargetFileName);
Log.d("DownloaderThreadClass", F.toString() + TargetFileName);
RandomAccessFile file = new RandomAccessFile(F, "rw");
file.seek(StartingByte);
InputStream stream = connection.getInputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int nRead = 0;
int start = 0;
int i = 0;
while ((nRead = stream.read(buffer, start, bufferSize)) > 0) {
file.write(buffer, 0, nRead);
//start += bufferSize + 1;
Log.i("DownloaderThreadClass:" + ThreadName + ": ", "Chunk: " + i + "copied" );
i += 1;
}
file.close();
stream.close();
connection.disconnect();
}catch(Exception e){
Log.e("DownloaderThreadClass", "Some exception: " + e.getMessage());
}
return null;
}
The above code is being called like this:
protected Void doInBackground(Void... params) {
int chunkSize = 0;
int[] startByte = new int[3];
int[] endByte = new int[3];
try{
int fileSize = this.getFileSize();
if(fileSize > 0 && fileSize <= 1024 * 1024){
new DownloaderThreadClass("1", f, "http://ift.tt/1FPNdqb").execute();
}else if(fileSize > 1024 * 1024){
chunkSize = Math.round(fileSize / 3);
startByte[0] = 0;
endByte[0] = chunkSize - 1;
startByte[1] = chunkSize;
endByte[1] = chunkSize + chunkSize - 1;
startByte[2] = chunkSize + chunkSize;
endByte[2] = fileSize;
for (int i = 0; i < 3; i++){
new DownloaderThreadClass(Integer.toString(i), f, "http://ift.tt/1FPNdqb", startByte[i], endByte[i]).execute();
}
}
}catch(IOException e){
Log.e("DownloaderClass", "Exception getting file size: " + e.getMessage());
}
return null;
}
As you will see, I have two different classes, both extending AsynTask, and the flow is like this: Activity calls the first class on a click button and the first class class the second class in a loop of 3 iterations.
Sample URL: http://ift.tt/1FPNdqb
Android bug in Slide Activity transition
So in trying to use the Slide Activity transition but with a different gravity, the app crashes on using Gravity.START, using this:
getwindow().setExitTransition(new Slide(Gravity.START));
and I get this error:
IllegalArgumentException: Invalid slide direction
But yet if you look in the source code, that specific constructor above calls setSlideEdge() in which case that method goes through a switch statement to set the Gravity you specified earlier:
switch (slideEdge) { case Gravity.LEFT: mSlideCalculator = sCalculateLeft; break; case Gravity.TOP: mSlideCalculator = sCalculateTop; break; case Gravity.RIGHT: mSlideCalculator = sCalculateRight; break; case Gravity.BOTTOM: mSlideCalculator = sCalculateBottom; break; case Gravity.START: mSlideCalculator = sCalculateStart; break; case Gravity.END: mSlideCalculator = sCalculateEnd; break; default: throw new IllegalArgumentException("Invalid slide direction"); }
Gravity.LEFT works just fine, but because I want RTL support, it only makes sense to instead use Gravity.START. I'm confused as to why the default case is executed in this switch statement, and the only explanation for it is it's a bug.
I'd report it to Google but they don't have public ways of reporting API bugs like this, and in this case the bug isn't exactly obvious to fix. So, PSA to anyone that wants to use the Slide animation with a Gravity of START.
decode json object sent form android app to php server
I am sending json object from android as such:
//Create JSONObject here
JSONObject json = new JSONObject();
json.put("key", String.valueOf(args[0]));
String postData=json.toString();
// Send POST output.
printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeUTF(URLEncoder.encode(postData,"UTF-8"));
Log.i("NOTIFICATION", "Data Sent");
printout.flush ();
printout.close ();
When it is sent to the server it looks like the following code snippet. ???%7B%22key%22%3A%22value%22%7D I should add the first ??? are in a diamond each. When I decode the whole json object I get null. In the php server I have
$somevar=json_decode(json, true);
which returns null. Can someone point me on how to retrieve the json value? Thanks so much:)
Ionic background doesn't display in app
According to the Ionic forum (http://ift.tt/1GPuMhq) the backgroun image should display if you put it on the ion-content from the css file, like I'm doing:
.scroll-content {
background:url(/img/splash2.jpg);
background-size: cover;
background-repeat: no-repeat;
}
but it displays in every page in ionic serve but in none if you run the app on a device.
Any ideas?
Retrofit not parsing JSONObject
A successful login returns the following JSONObject from a server:
{"success":true,"message":"Sign in success.","response_data":{"user_id":"24", "email_id":"user@gmail.com", "secret_code": "You did it!"}}
I want to put the response_data info into my User object. I used to do something like this:
String getResponse = jsonObject.getString("response_data");
Gson gson = new GsonBuilder()
.disableHtmlEscaping()
.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
.setPrettyPrinting()
.serializeNulls()
.create();
//All the data in the `response_data` is initialized in `User`
User user = gson.fromJson(getResponse, User.class);
Now I tried doing the same in retrofit:
Initializing RestAdapter + Interface:
public class ApiClient {
private static RetrofitService sRetrofitService;
public static RetrofitService getRetrofitApiClient() {
if (sRetrofitService == null) {
RestAdapter restAdapter = new RestAdapter.Builder()
.setLogLevel(RestAdapter.LogLevel.FULL)
.setEndpoint("http://xxx.xxx.xxx.xxx/")
.build();
sRetrofitService = restAdapter.create(RetrofitService.class);
}
return sRetrofitService;
}
public interface RetrofitService {
@FormUrlEncoded
@POST("/login")
public void login(@Field("email_id") String emailId, @Field ("password") String password,
Callback <User> callback);
}
}
MainActivity:
ApiClient.getRetrofitApiClient().login(email.getText().toString(), password.getText().toString(),
new Callback<User>() {
@Override
public void success(User user, Response response) {
User user1 = user; //null
Toast.makeText(this, "user is: "+user1.toString(), Toast.LENGTH_SHORT).show();
}
@Override
public void failure(RetrofitError error) {
Toast.makeText(this, "Failed Login", Toast.LENGTH_SHORT).show();
}
});
User:
public class User {
private String userId;
private String emailId;
private String code;
public User() {
}
... getters
... setters
}
The Retrofit code in MainActivity works and I get this response in my log:
{"success":true,"message":"Sign in success.","response_data":{"user_id":"24", "email_id":"user@gmail.com", "secret_code": "You did it!"}}
However it doesn't parse the response_data into my User object.
How do I fix this?
Google Play Services: Can't solve the SIGN_IN_REQUIRED error
Before I back-pedalled into using the clean template activity, I had manually created an app that uses the GoogleAPIClient, which resulted in the app working (probably) on my device, but not on any other.
From creating the template Google Play activity, I only changed the manifest to include the app_id that I have registered with my Google Play Service account. When launching the app it shows a brief "Logging in" popup from Google Play, then continually tries to reconnect. Have tried with different devices on different computers. Have tried with both the owner's and assigned tester accounts. Same result.
I can't use any invite or room creating services.
Here is my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://ift.tt/nIICcg"
package="com.example.kai.twincrawler" >
<application
android:allowBackup="true"

SoundCloud intents limited
Firstly, I was directed by my email to the developers to come here with my issue.
Hi, Simple Last.fm Scrobbler plans on having basic SoundCloud support in the newest version, but we have a problem with SoundCloud only releasing track strings of about 40 characters in length. Hence the information sent to last.fm or libre.fm is incomplete.
com.android.music.metadatachanged is the action being monitored.
The alternative My Cloud Player gives the full length track strings.
I was hoping to get feedback from SoundCloud Mobile developers about what is causing the track length shortages and if it will ever be fixed.

Send Android Parse Push Notification to segment
I am trying to send push notifications to segment users in Android. Below is the code, it worked for few trials but now the same code send the push to everyone instead of the intended receiver (at the least that is what is shown on the dashboard). Anything I am doing wrong here?
ParseQuery pushQuery = ParseInstallation.getQuery();
pushQuery.whereEqualTo("user", ParseObject.createWithoutData("_User", mObject.get(position)));//receiver
ParsePush push = new ParsePush();
push.setQuery(pushQuery);
push.setMessage(alias +" followed you");
push.sendInBackground();
mObject.get(position) is where I get the objectId of the receiver in the installation class from and 'user' is a pointer to the _User class. Thanks

Android - Review video captured by custom camera before saving it
I can't find any information for this anywhere: I have created an Android custom camera in order to capture short videos. Instead of saving it directly on my mobile phone gallery, I would like first to review the video that I just capured, by watching it right after the recording, and with 2 buttons "Delete" and "OK".
Anyone knows how to do it? Do I have to create a new activity and using an intent?
Here is the current code which save the captured video on my mobile:
/** Saving Media Files */
/* Create a File for saving an image or video */
private static File getOutputMediaFile(int type){
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "MyCameraApp");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
Log.d("The app", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else if(type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"VID_"+ timeStamp + ".mp4");
} else {
return null;
}
return mediaFile;
}
Thank you so much for your help.

Fatal spin-on-suspend
I am getting this error after around 45 minutes of my service running, and then it crashes. I see this group of lines in the logcat when it does crash:
Thread pingo = new Thread(new Runnable()
{
public void run()
{
while (true)
{
if(socket2 != null)//Line 481
{
try {
ping = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket2.getOutputStream())), true);//Line 484
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
ping.write("0000:PING" + "\r\n");
ping.flush();
// delay 5 seconds
try
{
Thread.sleep(5000);
} catch (InterruptedException e)
{
break;
}
}
}
}
What this is supposed to do is ping the server every 5 seconds to ensure that the connection is kept alive. Is this the wrong way of doing this? Like I said it takes about 45 minutes or so for the crash to occur..
this is a snippet of the Logcat:

Javassist - CannotCompileException: constructor/method declaration not found
I've got the following class which i want to use in my generated code with Javassist.
public class SomeClass {
private String someString;
private Object someValue;
public SomeClass() {}
public SomeClass(String someString, Object someValue) {
this.someString = someString;
this.someValue = someValue;
}
public void setSomeValue(Object someValue) {
this.someValue = someValue;
}
In Javassist i analyse some classes and their fields and then try to instatiate my SomeClass-class. But i get the following error for each field which has another type then java.lang.Object.
javassist.CannotCompileException: [source error] setSomeValue(int) not found in com.test.SomeClass
and
javassist.CannotCompileException: [source error] setSomeValue(double) not found in com.test.SomeClass
and so on. The same happens when i try to use the constructor.
Why this doesn't work?
By the way, Javassist is used in conjunction with Android.

Cant validate Login on Android app using an api request
i'm trying to create a login form that connects to an API and authorizes the username and password but whenever i press the onClickListener which is my LogIn button the app crashes. The username and password is hardcoded in my code.
Code:
public class LoginActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(layout.activity_login);
Button buttonLogin = (Button)findViewById(id.buttonLogin);
EditText uEmail = (EditText) findViewById(id.emailField);
EditText uPassword = (EditText) findViewById(id.passwordField);
buttonLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final OkHttpClient client = new OkHttpClient();
client.setAuthenticator(new Authenticator() {
@Override
public Request authenticate(Proxy proxy, Response response) throws IOException {
String credential = Credentials.basic("username", "password");
return response.request().newBuilder()
.header("Authorization", credential)
.build();
}
@Override
public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
return null;
}
});
Request request = new Request.Builder().url("MyUrlThatIdontWannaShow").build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
Context context = getApplicationContext();
CharSequence text = "Error";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
@Override
public void onResponse(Response response) throws IOException {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();

How can I test setResult() in an Android Espresso test?
Is there any good way to test the result code and data in an Android Espresso test? I am using Espresso 2.0.
Suppose I have an Activity called BarActivity.class, which upon performing some action, calls setResult(int resultCode, Intent data) with the appropriate payload.
I'd like to write a test case to verify the resultCode and data. However, because setResult() is a final method, I can't override it.
Some options I thought about were:
- Define a new method like
setActivityResult()and just use that so it can be intercepted, etc... - Write a test-only TestActivity that will call
startActivityForResult()onBarActivityand check the result inTestActivity.onActivityResult()
Trying to think what's lesser of the two evils, or if there's any other suggestions on how to test for this. Any suggestions? Thanks!

Android serialization issue
I am trying to write object data to a file (how it's done in a standard java program) in an android program and am running in to some issues. Here's the code:
public static final String storeDir = "Adata";
public static final String storeFile = "albums";
public static void write(ArrayList<Album> albums) throws IOException {
ObjectOutputStream oos = new ObjectOutputStream( new FileOutputStream(storeDir + File.separator + storeFile));
oos.writeObject(albums);
}
public static ArrayList<Album> read() throws IOException, ClassNotFoundException{
ObjectInputStream ois = new ObjectInputStream( new FileInputStream(storeDir + File.separator + storeFile));
return (ArrayList<Album>)ois.readObject();
}
At startup the app crashes and says, "java.io.FileNotFoundException: Adata/albums (No such file or directory)
The folder Adata folder is in the project folder at the same point as the src. Any help is appreciated. Thanks.

Android gradle modules with the same name
I am working on an Android project that uses the following dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.17</version>
</dependency>
However this dependency has 2 definitions of the module javax/inject as shown here in the gradle dependency tree:
+--- org.glassfish.jersey.core:jersey-client:2.17
| +--- org.glassfish.jersey.core:jersey-common:2.17
| | +--- org.glassfish.hk2:hk2-api:2.4.0-b10
| | | +--- javax.inject:javax.inject:1
| | +--- org.glassfish.hk2.external:javax.inject:2.4.0-b10
When attempting to run the Android application I get the error:
com.android.dex.DexException: Multiple dex files define L/javax/inject/Inject
I have tried excluding either of these modules but that does not work because the dependency relies on both of them to make method calls.
Are there any other solutions to resolve this conflict?

android:src="@drawable/a"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
and activity_tabbed.xml contains :
<android.support.v4.view.ViewPager xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4" android:id="@+id/pager"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context="com.webraya.t0.t0.Tabbed" />
When I run the app and touch the imagebutton and the Tabbed activity starts, the result is :
when I swipe from right to left, it seems I have 3 tabs with the same picture. I don't know why there is no tab header, and why there are three tabs with the same content, how to create headers and change tabs contents? My theme is Theme.AppCombat.Light.DarkActionBar
Any help would be appreciated.

Android invalid resource directory name:appcompat_v7\bin\res crunch
My app add the v7 lib under the libraries dependency. When I run the build script(under Eclipse), I got the following error:
[mergemanifest] Manifest merger disabled. Using project manifest only.
[echo] Handling aidl files...
[aidl] No AIDL files to compile.
[echo] ----------
[echo] Handling RenderScript files...
[echo] ----------
[echo] Handling Resources...
[aapt] Generating resource IDs...
[aapt] invalid resource directory name: D:\Workspace\appcompat_v7\bin\res crunch
I tried everything, but can't figure out how to solve it. Any help? This happens with all libraries I added, so I'm forced to use the .jar instead but v7 appears has no jar.
