Playing media player inside fragment with background service

Playing media player inside fragment with background service - android

I'm trying to implement live stream radio by using fragment and background service, however every time I click to radio button on navigation drawer I couldn't reach the player because it generates one more and I can only control the second one. Here is my fragment class.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_radio, container, false);
init(v);
ApiManager.getInstance().getRadioBroadcast(new ApiResponseLive.GetLiveBroadcastListener() {
#Override
public void onSuccess(StreamModel days) {
turnRadioOn(ApiManager.streamModel);
}
#Override
public void onFailure(String responseString) {
}
});
registerHandler(v);
return v;
}
private void turnRadioOn(StreamModel streamModel) {
HashMap<Integer, ArrayList<GenericStreamItem>> broadcastDays = new HashMap<>();
streamModel.setStreamAllArrays(broadcastDays);
BroadcastPagerAdapter radioPagerAdapter = new BroadcastPagerAdapter(getChildFragmentManager(), getContext(), TAG);
radioPager.setAdapter(radioPagerAdapter);
}
private void init(View v) {
radioPager = (ViewPager) v.findViewById(R.id.broadcastRadioPager);
radioTabLayout = (TabLayout) v.findViewById(R.id.tabsDays);
radioTabLayout.setupWithViewPager(radioPager);
radioPlay = (ToggleButton) v.findViewById(R.id.playButton);
radioScrollView = (ScrollView) v.findViewById(R.id.radioScroll);
}
private void start(String url) {
try {
mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setOnPreparedListener(this);
mp.setDataSource(url);
mp.prepareAsync();
mp.setOnCompletionListener(this);
Log.e("Radio::", "Working");
} catch (Exception e) {
Log.e("StreamAudioDemo", e.getMessage());
e.printStackTrace();
}
}
private void stop() {
try {
mp.pause();
mp.stop();
mp.reset();
mp.release();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void stopRadio() {
try {
Log.e("stopRadio::", "Pause");
mp.pause();
mp.stop();
mp.reset();
mp.release();
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
#Override
public void onCompletion(MediaPlayer mp) {
}
private void registerHandler(View v) {
radioPlay.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
Log.e("Toggle::", "Enabled");
radioService = new RadioService();
radioService.initMediaPlayer(ApiManager.RADIO_URL);
} else {
Log.e("Toggle::", "Disabled");
stop();
stopRadio();
radioService.onDestroy();
}
}
});
v.findViewById(R.id.radioBroadcast).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
radioScrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
});
}
public class RadioService extends Service implements MediaPlayer.OnErrorListener {
public void initMediaPlayer(String url) {
// ...initialize the MediaPlayer here...
ApiManager.getInstance().getRadioURL(new ApiResponseLive.GetTVStreamUrlListener() {
#Override
public void onSuccess(String tvUrl) {
start(ApiManager.RADIO_URL);
mp.setOnErrorListener(RadioService.this);
}
#Override
public void onFailure(String responseString) {
}
});
}
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// ... react appropriately ...
// The MediaPlayer has moved to the Error state, must be reset!
mp.reset();
return false;
}
#Override
public void onDestroy() {
if (mp != null) mp.release();
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
}
Here is how I call fragment:
RadioFragment radioFragment = new RadioFragment();
fragment = fm.findFragmentByTag("radio");
radioDrawer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (fragment == null) {
fm.beginTransaction()
.remove(fm.findFragmentById(R.id.activity_content))
.add(R.id.activity_content, radioFragment,
"radio").addToBackStack("main").commit();
} else {
fm.beginTransaction().replace(R.id.activity_content,
radioFragment, "radio");
}
fullView.closeDrawers();
}
});

Android background audio with a live audio stream

I have come along in leaps and bound with my first android app in the last three days. This is my last hurdle. How do I get my app to run a background Service that will allow the audio to keep playing? I have tried several examples I could find but they are based on playing a local (or streamed) mp3 file as opposed to a live (Icecast) mp3 stream.
Here's my code currently, everything works except background audio.
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageButton;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
private ImageButton btn;
private ImageView img;
private boolean playPause;
private MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = findViewById(R.id.playPause);
img = findViewById(R.id.radioTower);
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int extra) {
mp.reset();
return false;
}
});
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
//mp.start();
}
});
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (!playPause) {
if(!mediaPlayer.isPlaying()) {
mediaPlayer.start();
btn.setBackgroundResource(R.drawable.ic_rounded_pause_button);
img.setImageResource(R.drawable.ic_toweron);
img.setAlpha(1.0f);
playPause = true;
}
} else {
if(mediaPlayer.isPlaying()) {
mediaPlayer.pause();
btn.setBackgroundResource(R.drawable.ic_play_button);
img.setImageResource(R.drawable.ic_toweroff);
img.setAlpha(0.3f);
playPause = false;
}
}
}
});
try {
mediaPlayer.setDataSource("http://bbcmedia.ic.llnwd.net/stream/bbcmedia_radio2_mf_p");
mediaPlayer.prepareAsync();
} catch (Exception e) {
e.printStackTrace();
}
}
protected void onStop() {
super.onStop();
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.release();
mediaPlayer = null;
}
}
#Override
protected void onDestroy() {
super.onDestroy();
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.release();
mediaPlayer = null;
}
}
}
Any help would be much appreciated.

you can start your service from activity like this.
public void startMusicService() {
Intent serviceIntent = new Intent(MainActivity.this, MusicService.class);
serviceIntent.setAction(Constants.ACTION.STARTFOREGROUND_ACTION);
startService(serviceIntent);
bindService(serviceIntent, mConnection, Context.BIND_AUTO_CREATE);
}
for stop service use this code
public void stopMusicService() {
if (service != null) {
try {
service.stop();
unbindService(mConnection);
stopService(new Intent(MainActivity.this, service.getClass()));
service = null;
} catch (IllegalArgumentException ex) {
stopService(new Intent(MainActivity.this, service.getClass()));
service = null;
ex.printStackTrace();
}
}
}
for bind service with activity use this
private ServiceConnection mConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName className,
IBinder _service) {
MusicService.LocalBinder binder = (MusicService.LocalBinder) _service;
service = binder.getServiceInstance(); //Get instance of your service!
service.registerClient(MainActivity.this); //Activity register in the service as client for callabcks!
if (listHolder != null) {
initilizeSongsList(listHolder.list, listHolder.position);
}
}
#Override
public void onServiceDisconnected(ComponentName arg0) {
}
};
where service is music service object in activity MusicService service;

So this is the working service for a single live stream URL thanks to asim.
public class StreamService extends Service implements MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener {
public static final String ACTION_PLAY = "com.example.action.PLAY";
private static final String STREAM_URL = "...";
private static final String TEST_URL = "https://www.nasa.gov/mp3/586447main_JFKwechoosemoonspeech.mp3";
MainActivity mainActivity;
MediaPlayer mediaPlayer = null;
WifiManager.WifiLock wifiLock;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
public class LocalBinder extends Binder {
public StreamService getServiceInstance() {
return StreamService.this;
}
}
#Override
public void onCreate() {
super.onCreate();
}
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mediaPlayer = new MediaPlayer();
mediaPlayer.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
mediaPlayer.setOnErrorListener(this);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
wifiLock = ((WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE))
.createWifiLock(WifiManager.WIFI_MODE_FULL_HIGH_PERF, "mylock");
wifiLock.acquire();
try {
// Set the stream URL location
mediaPlayer.setDataSource(TEST_URL);
// prepareAsync must be called after setAudioStreamType and setOnPreparedListener
mediaPlayer.prepareAsync();
} catch (Exception e) {
e.printStackTrace();
}
}
return START_STICKY;
}
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// ... react appropriately ...
// The MediaPlayer has moved to the Error state, must be reset!
return false;
}
void switchButton() {
mainActivity.checkPlaying(!mediaPlayer.isPlaying());
}
public boolean play() {
if (mediaPlayer != null) {
//switchButton();
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
return false;
} else {
mediaPlayer.start();
return true;
}
}
return false;
}
public void stop() {
try {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
/** Called when MediaPlayer is ready */
public void onPrepared(MediaPlayer player) {
//player.start();
}
#Override
public void onDestroy() {
super.onDestroy();
if( wifiLock != null) wifiLock.release();
if (mediaPlayer != null) mediaPlayer.release();
}
public void registerClient(MainActivity activity) {
mainActivity = activity;
}
public boolean isplaying() {
return mediaPlayer == null ? false : mediaPlayer.isPlaying();
}
}
Which is implemented in the main activity:
public class MainActivity extends AppCompatActivity {
private ImageButton btn; // Play | Pause toggle button
private ImageView img; // Radio tower image that alternates between on and off
StreamService service;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Bind the view buttons to local variables
btn = findViewById(R.id.playPause);
img = findViewById(R.id.radioTower);
startStream();
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (service.isplaying()) {
Log.d("pause","Pause Playback");
} else {
Log.d("play", "Start Playback");
}
}
});
}
public void startStream() {
Intent serviceIntent = new Intent(MainActivity.this, StreamService.class);
serviceIntent.setAction(StreamService.ACTION_PLAY);
startService(serviceIntent);
bindService(serviceIntent, mConnection, Context.BIND_AUTO_CREATE);
}
public void stopStream() {
if (service != null) {
try {
service.stop();
unbindService(mConnection);
stopService(new Intent(MainActivity.this, service.getClass()));
service = null;
} catch (IllegalArgumentException ex) {
stopService(new Intent(MainActivity.this, service.getClass()));
service = null;
ex.printStackTrace();
}
}
}
private ServiceConnection mConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName className,
IBinder _service) {
StreamService.LocalBinder binder = (StreamService.LocalBinder) _service;
service = binder.getServiceInstance(); //Get instance of your service!
service.registerClient(MainActivity.this); //Activity register in the service as client for callabcks!
}
#Override
public void onServiceDisconnected(ComponentName arg0) {
}
};
}
Service starts just fine, I just need to learn how to access the service object to implement the play pause functionality.

How do i setMediaPlayer inside of a fragment?

I have a fragment where i am using media player and using my own custom controller class. I am not being able to set controller.setMediaPlayer inside fragment. I have implemented VideoControllerView.MediaPlayerControl class in fragment.
My fragment class is :
public class HomeFragment extends Fragment implements SurfaceHolder.Callback, VideoControllerView.MediaPlayerControl {
#BindView(R.id.videoSurfaceContainer)
FrameLayout videoContainer;
#BindView(R.id.videoSurface)
SurfaceView videoSurface;
#BindView(R.id.progress)
ProgressBar progressBar;
#BindView(R.id.errorTv)
RelativeLayout relativeLayout;
#BindView(R.id.errorTextView)
TextView errorTextView;
public MediaPlayer player;
public VideoControllerView controller;
private Context context;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_home, container, false);
ButterKnife.bind(this, v);
player = new MediaPlayer();
controller = new VideoControllerView(getActivity());
SurfaceHolder videoHolder = videoSurface.getHolder();
videoHolder.addCallback(this);
progressBar.setVisibility(View.VISIBLE);
playVideo("http://202.166.200.170:8081/otv/aastha.stream/playlist.m3u8");
relativeLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
relativeLayout.setVisibility(View.GONE);
player.reset();
progressBar.setVisibility(View.VISIBLE);
playVideo("http://202.166.200.170:8081/otv/aastha.stream/playlist.m3u8");
} catch (Exception e) {
e.printStackTrace();
}
}
});
return v;
}
#Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
player.setDisplay(surfaceHolder);
}
#Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
}
#Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
}
public void playVideo(String link) {
try {
videoSurface.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (controller.isShowing())
controller.hide();
else
controller.show();
return false;
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer();
controller.setAnchorView((FrameLayout) getActivity().findViewById(R.id.videoSurfaceContainer));
player.start();
progressBar.setVisibility(View.GONE);
if (relativeLayout.isShown())
relativeLayout.setVisibility(View.GONE);
}
});
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setDataSource(getActivity(), Uri.parse(link));
try {
player.prepareAsync();
} catch (Exception e) {
e.printStackTrace();
}
player.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
progressBar.setVisibility(View.GONE);
errorMessage("Streaming Error");
player.reset();
errorTextView.setText(getResources().getString(R.string.error_msg_video));
return false;
}
});
player.setScreenOnWhilePlaying(true);
Log.d("after click", "last try");
} catch (Exception e) {
e.printStackTrace();
}
}
public void errorMessage(String message) {
try {
relativeLayout.setVisibility(View.VISIBLE);
progressBar.setVisibility(View.GONE);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void start() {
}
#Override
public void pause() {
}
#Override
public int getDuration() {
return 0;
}
#Override
public int getCurrentPosition() {
return 0;
}
#Override
public void seekTo(int pos) {
}
#Override
public boolean isPlaying() {
return false;
}
#Override
public boolean canPause() {
return false;
}
#Override
public boolean isFullScreen() {
return false;
}
#Override
public void toggleFullScreen() {
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
context = activity;
}
if you see inside playVideo method inside setOnpreparedListener i am getting error in controller.setMediaPlayer() because i am not being able to pass the context here.
what can be done here to solve the error?

This is how we can use controller.setMediaPlayer()
// Implement MediaPlayer.OnPreparedListener
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer(this);
controller.setAnchorView((FrameLayout)
findViewById(R.id.videoSurfaceContainer));
player.start();
}
// End MediaPlayer.OnPreparedListener
This is example to use costume controller

If you want, you could get the context from there using HomeFragment.this.getContext(), like:
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer(HomeFragment.this.getContext());
controller.setAnchorView((FrameLayout) getActivity().findViewById(R.id.videoSurfaceContainer));
player.start();
progressBar.setVisibility(View.GONE);
if (relativeLayout.isShown())
relativeLayout.setVisibility(View.GONE);
}
});

I just moved controller.setMediaPlayer(this); to onCreateView and it worked.

Android media player won't start

prepareAsynch should be called after setOnPreparedListener, otherwise it may happen that prepareAsynch finished working before the listener is assigned.

How can I fix this. I have no idea.
Can anyone help me. Please !!!

You need to stop and release the media player before your activity finishes. Try adding this to your activity:
#Override
protected void onDestroy() {
super.onDestroy();
if(mMediaPlayer != null)
{
mMediaPlayer.stop();
mMediaPlayer.release();
}
}
