Music app that reads external storage audio is working on emulator and not working on real devices

I have a list view that displays all the songs in my device in the application, then when I click on the song another activity opens where you can play the song, on emulator when I click on the song in the list it takes me to the other activity and I can play and hear the song, but on real device I'm not getting any error but when I select an item from the list, I get the name and artist of the song, but when i click on play it doesn't work, I don't hear sound nor can I jump to middle of song etc..
the list is like this:
When clicked:
I'm using media player to read the audio files, and the code for my main activity is:

The code for my listviewmusic activity from where I retrieve title artist and audio is:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_music);

songArrayList = new ArrayList<>();
songsAdapter = new SongsAdapter(this, songArrayList);
tvSongs.setAdapter(songsAdapter);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, REQUEST_PERMISSION);
return;
}else {
// you have permission to read from external storage
getSongs();
}
tvSongs.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Songs song = songArrayList.get(position);
Intent openMusicPlayer = new Intent(ListMusicActivity.this, MusicPlayerOffline.class);
openMusicPlayer.putExtra("song", song);
startActivity(openMusicPlayer);
}
});
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == REQUEST_PERMISSION){
if (grantResults[0] == PackageManager.PERMISSION_GRANTED){
getSongs();
}
}
}
private void getSongs() {
// read songs from phone
ContentResolver contentProvider = getContentResolver();
Uri songUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor songCursor = contentProvider.query(songUri,null,null,null,null);
if (songCursor != null && songCursor.moveToNext()) {
int indexTitle = songCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int indexArtist = songCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
int indexData = songCursor.getColumnIndex(MediaStore.Audio.Media.DATA);
do {
String title = songCursor.getString(indexTitle);
String artist = songCursor.getString(indexArtist);
String path = songCursor.getString(indexData);
songArrayList.add(new Songs(title, artist, path));
}while (songCursor.moveToNext());
}
songsAdapter.notifyDataSetChanged();
}
}
My adapter:
public class SongsAdapter extends ArrayAdapter<Songs> {
public SongsAdapter(#NonNull Context context, #NonNull List<Songs> objects) {
super(context,0, objects);
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_song, null);
TextView tvTitle = convertView.findViewById(R.id.tvTitle);
TextView tvArtist = convertView.findViewById(R.id.tvArtist);
Songs song = getItem(position);
tvTitle.setText(song.getTitle());
tvArtist.setText(song.getArtist());
return convertView;
}
}
I have no idea why it's not working, I don't get any error in the logcat, the music just doesn't start, it stays frozen at 0:00, and I cant jump to middle of it etc, although the name and artist name get obtained successfully just no audio

Message not received when sending a message from Wear to Phone [MessageAPI]

I am trying to send a simple message from my wear [Emulator] to my android phone, The message should have been sent according to my logs on the wear but it does not trigger my "showToast" method on my phone [it should be triggered when a message is received]. Anyone has an idea what I could be doing wrong?

This is my Wear logic [I have a button that sends the showToast message]
public class MainActivity extends WearableActivity {
private static final long CONNECTION_TIME_OUT_MS = 2500;
private static final String TAG = MainActivity.class.getSimpleName();
private CircularButton mSendButton;
private List<Node> myNodes = new ArrayList<>();

mSendButton = (CircularButton)findViewById(R.id.sendToast);
mSendButton.setOnClickListener(new View.OnClickListener() {
#Override

sendToastMessage();
}
});
mClient = new GoogleApiClient.Builder(this)
.addApiIfAvailable(Wearable.API)
.build();
getNodes();
mContainerView = (BoxInsetLayout) findViewById(R.id.container);

Log.d(TAG,"Adding Node: "+n.getDisplayName());
myNodes.add(n);
}
Log.d(TAG,"Getting nodes DONE!");
}
}).start();
return null;
}
}
This is my ReceiveMessageService in Mobile
public class ReceiveMessageService extends WearableListenerService {
#Override
public void onMessageReceived(MessageEvent messageEvent) {
Log.d("ReceiveMessageService","onMessageReceived");
//if(messageEvent.getPath().equals("/showToast")) {
showToast(messageEvent.getPath());
//}
}
private void showToast(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}
This is my MainActivity in Mobile
public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{
private static final String TAG = MainActivity.class.getSimpleName();
private GoogleApiClient mGoogleApiClient;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)

.build();
mGoogleApiClient.connect();
}

Log.d(TAG,"onConnectionSuspended");
}
#Override

Log.d(TAG,"onConnectionFailed");
}

It looks like you are using wrong pathPrefix in your mobile side AndroidManifest. Try to replace
<data android:scheme="wear" android:host="*" android:pathPrefix="/prefix" />
with
<data android:scheme="wear" android:host="*" android:pathPrefix="/showToast" />
Edit
Also keep in mind that MessageApi is not guarantee to deliver a message even if it returns a successful result code as Google's document stated:
Note: A successful result code does not guarantee delivery of the message. If your app requires data reliability, use DataItem objects or the ChannelApi class to send data between devices.

Updating a CircularButton in a custom Fragment created with FragmentGridPagerAdapter

I have a wearable app that has a couple of fragments created with FragmentGridPagerAdapter. One of the fragments has a couple of CircularButtons and I want to update the backcolor of the button when a message is received from handheld phone. I have no problems in receiving the message. However, button's color (or anything in UI) doesn't update. Do you know how can I fix this?
public class UIPageAdapter extends FragmentGridPagerAdapter {
private final Context mContext;
MainControlFragment[] mainControlFragments;
private List mRows;
uiChangeListener mUIChangeListener = new uiChangeListener();
public UIPageAdapter(Context ctx, FragmentManager fm) {
super(fm);
Log.i("pageAdapter", "constructor");
mContext = ctx;
mainControlFragments = new MainControlFragment[2];
mainControlFragments[0] = new MainControlFragment();
mainControlFragments[1] = new MainControlFragment();
LocalBroadcastManager.getInstance(ctx).registerReceiver(mUIChangeListener,new IntentFilter(Constants.BROADCAST_CONTROL_HOME));
}
#Override
public Fragment getFragment(int row, int col) {
Log.i("PageAdapter","Fragment #" + col +"is asked");
return mainControlFragments[col];
}
public void changeStatus(int button, boolean status) {
mainControlFragments[0].setStatus(button,status);
// notifyDataSetChanged();
}
public class uiChangeListener extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
String act = intent.getAction();
if (act == Constants.BROADCAST_CONTROL_HOME) {
int key = intent.getIntExtra(Constants.CONTROL_HOME_KEY,-1);
String command = intent.getStringExtra(Constants.CONTROL_HOME_COMMAND);
changeStatus(key,command.equals("on"));
}
}
}
#Override
public int getRowCount() {
return 1;
}
#Override
public int getColumnCount(int i) {
return 2;
}
}
Basically when a message received from the handheld device a WearableListener class broadcasts an update message to the UIPageAdapter
This is the listener class
public class ListenerService extends WearableListenerService
{
String tag = "ListenerService";
#Override
public void onMessageReceived(MessageEvent messageEvent) {
final String message = (new String(messageEvent.getData()));
Log.i(tag,message);
LocalBroadcastManager.getInstance(this).sendBroadcast(new Intent(Constants.BROADCAST_CONTROL_HOME)
.putExtra(Constants.CONTROL_HOME_KEY, messageEvent.getPath())
.putExtra(Constants.CONTROL_HOME_COMMAND,Integer.parseInt(message.substring(1)))
.putExtra("caller",tag));
}
#Override
public void onCreate() {
super.onCreate();
Log.i(tag, "onCreate");
}
}
Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</manifest>
Finally the custom fragment
public class MainControlFragment extends Fragment{
ViewGroup container;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.i("controlFragment","create");
this.container = container;
// Inflate the layout for this fragment
return inflater.inflate(R.layout.main_control, container, false);
}
public void setStatus(int button, boolean status) {
Log.i("controlFragment",button + " "+ status);
CircularButton[] btns = new CircularButton[4];
btns[0] = (CircularButton) container.findViewById(R.id.cbtnFront);
btns[1] = (CircularButton) container.findViewById(R.id.cbtnBack);
btns[2] = (CircularButton) container.findViewById(R.id.cbtnBed);
btns[3] = (CircularButton) container.findViewById(R.id.cbtnCoffee);
btns[button].setColor(status?Color.BLACK:Color.RED);
}
}
I also tried the notifyDataSetChanged(); method in UIPageAdapter however it it only calls onCreateView method in fragment. Any help is appreciated

I'm assuming you already resolved this but I had to add a call to invalidate() on the CircularButton after calling setColor():
_circularButton.setColor(ContextCompat.getColor(getActivity(), buttonColor));
_circularButton.invalidate();
Without the call to invalidate the UI only updated some of the time.

It may be that the AndroidManifest file has wrong information about which package LoginIntoFacebookActivity belongs to - there's a mismatch between the error trace you've posted and the manifest file.

Android: Twitter in WebView - Back to an Activity by callback

I try to create Twitter client and now I deal with authorization via OAuth protocol. I have created "Sign In" button to come in WebView and load twitter authorization URL, that's work. However, when the authorization is accepted successfuly and Twitter service redirect me to my callback I receive error web page in WebView. That is to say I am not redirected to my activity, I still stay in WebView. But if try the same way via browser, it`s working. What the problem is that?
Main Activivty:
public class Twitter extends Activity implements OnClickListener {
Button bSignIn;
TextView status;
private OAuthConsumer consumer;
private OAuthProvider provider;
private String url;
final String TAG = getClass().getName();
public void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.home);
bSignIn = (Button) findViewById(R.id.bSignIn);
status = (TextView) findViewById(R.id.tvStatus);
bSignIn.setOnClickListener(this);
}
public void onClick(View v) {

Constants.CONSUMER_SECRET);
provider = new CommonsHttpOAuthProvider(Constants.REQUEST_URL,
Constants.ACCESS_URL, Constants.AUTHORIZE_URL);
url = provider.retrieveRequestToken(consumer,
Constants.OAUTH_CALLBACK_URL);
} catch (Exception e) {

Intent i = new Intent(Twitter.this, TwitterWebView.class);
i.putExtra("url", Uri.parse(url).toString());
startActivityForResult(i, 1);
dialog.dismiss();
}
}
}
WebView for Twitter:
public class TwitterWebView extends Activity {

I did the same about others networks like LinkedIn, Foursquare. But instead of use the callback URL, I override the method shouldOverrideUrlLoading (WebView view, String url) in your WebViewClient (which is used to show the login page) to catch the access token and the token secret (if needed) by myself.
