Playing media player inside fragment with background service

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();
}
});

maybe problem is in this line
videoSurface.setVisibility(View.VISIBLE);
what am i doing wrong in my code?

Try player.release() in onComplation before player.start()

Play/Pause Media Player in Texture View Surface Texture Listener

I've implemented a recycler view and each item will play video. My problem is that I need to pause/play the video when it scrolls on/off the screen.
I've implemented that when the user scrolls the video keeps playing.
I have had an issue trying to keep track of the media player when the view scrolls off screen.
I have come up with a solution and I'm hoping I can get some advice to see if may be any issues with the solution.
So I'm using a texture view to display the media player in the recycler view as videoviews aren't compatible when looking to use a recycler or customise the controller.
So in the surface texture destroyed (signalling that the view has left the screen) I pause the media player and when the surfacetexture is available (signalling the view is on screen) I check if the media player is null (as it will be when the screen first loads) if not I start the media player. Below is my video player class in where you can see my implementation.
public class CustomVideoPlayer implements TextureView.SurfaceTextureListener, VideoControllerView.MediaPlayerControl, MediaPlayer.OnBufferingUpdateListener, MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener, MediaPlayer.OnVideoSizeChangedListener {

Android play video in surfaceview NullPointerException

I try to play video in surfaceview. I use Fragment (extends Fragment) and I have NullPointerException. I have no idea what am I doing wrong. First time I used Activity and in Activity project worked perfect but I use Fragment and I have error
This is a my source
public class Layout1 extends Fragment implements OnBufferingUpdateListener,

Error log

It seems that onSurfaceCreated is called before playVideo(). Initialize your mMediaPlayer (and handler too by the way) in Fragment's onCreate().
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
handler = new Handler();
playVideo();
}
private void playVideo() {
mcontroller = new MediaController(getActivity());
mcontroller.setVisibility(View.INVISIBLE);
mMediaPlayer = MediaPlayer.create(getActivity(), Uri.parse(video));
// implement a fallback mechanism if it fails, for example if no internet or 404
if (mMediaPlayer == null) {
Log.w("Layout1", "Faileded to create MediaPlayer");
return;
}
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setScreenOnWhilePlaying(true);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_layout1, null);
SurfaceView v = (SurfaceView) view
.findViewById(R.id.screen_tutorial_video_surface);
v.getHolder().addCallback(this);
return view;
}
#Override
public void surfaceCreated(SurfaceHolder arg0) {
if (mMediaPlayer == null) {
// implement a fallback mechanism if it fails, for example if no internet or 404
Log.w("Layout1", "MediaPlayer was not created");
return;
}
// the holder reference is already passed as arg0 here
mMediaPlayer.setDisplay(arg0);
try {
// progressDialog.dismiss();
mMediaPlayer.start();
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
After you removed catch (Exception e) in playVideo()
If you looked closely in logs you could have seen
Permission failure: android.permission.INTERNET from uid=10052 pid=1129
Request requires android.permission.INTERNET
Unable to create media player
create failed:
java.io.IOException: setDataSource failed.: status=0x80000000
Thus you also need to add permission
<uses-permission android:name="android.permission.INTERNET"/>
If it wasn't for the project you've attached we would never knew.

Audio Streaming Seekbar Hides while song is playing

I can't find a way to stop hiding the seekbar. As soon as the song plays the seekbar hides after 2-3 sec. I am really new into this so not really sure how I can approach to this issue. I tried putting mediaController.show() into my methods when the song is playing but no luck. I found this code from a Youtube Channel below is the code:
public class MainActivity extends ListActivity implements OnPreparedListener,
MediaController.MediaPlayerControl {
private static final String TAG = "AudioPlayer";
private ListView list;
private MainArrayAdapter adapter;
private MediaPlayer mediaPlayer;
private MediaController mediaController;

setContentView(R.layout.activity_main);
list = getListView();
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnPreparedListener(this);

ArrayList<String> array_list_music = new ArrayList<String>();
array_list_music.add("Sammy Kaye And His Orchestra" + " ### "
+ "Minka (1941)" + " ### "
+ "http://incoming.jazz-on-line.com/a/mp3w/1941_149.mp3");
adapter = new MainArrayAdapter(MainActivity.this, array_list_music);
setListAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Object item = getListView().getItemAtPosition(arg2);
String the_list_item = item.toString();
Toast.makeText(MainActivity.this,
"You clicked " + the_list_item, Toast.LENGTH_LONG)
.show();
String[] aux = the_list_item.split(" ### ");
String url_to_play = aux[2];
playAudio(url_to_play);
}
});
}
