How to make service for Play Pause of music Player

Here is my code which is play song from the resources folder and now I am stuck with service so please help me.....
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mHandler=new Handler();
seekBar=findViewById(R.id.seekBar);
mp=MediaPlayer.create(MainActivity.this,R.raw.ed);
final int Duration=mp.getDuration();
Media Player Prepared Listener.....
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
seekBar.setMax(mp.getDuration());
updateSeekBar();
mp.start();
}
});
Runnable Thread for Seekbar.....
runnable=new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
Phone State Listener for Incoming and Outgoing Calls.....
PhoneStateListener phoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (state == TelephonyManager.CALL_STATE_RINGING) {
mp.pause();
} else if(state == TelephonyManager.CALL_STATE_IDLE) {
mp.start();
} else if(state == TelephonyManager.CALL_STATE_OFFHOOK) {
mp.pause();
}
super.onCallStateChanged(state, incomingNumber);
}
};
TelephonyManager mgr = (TelephonyManager)
getSystemService(TELEPHONY_SERVICE);
if(mgr != null) {
mgr.listen(phoneStateListener,
PhoneStateListener.LISTEN_CALL_STATE);
}
}
Seek Bar Update Method....
private void updateSeekBar() {
seekBar.setProgress(mp.getCurrentPosition());
mHandler.postDelayed(runnable, 100);
}
}
Now, it's my service code.......
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;
public class MyMusicService extends Service {
On Create method of service....
#Override
public void onCreate() {
super.onCreate();
}
On start method of service....
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
On Destroy method of service....
#Override
public void onDestroy() {
super.onDestroy();
}
Binder of Service.....
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}

see i have added the code of service which is work for me.
you can try this code for your need

MediaController doesn't seem to show up

I have an android app with a detail activity, that detail activity has few tabs with underlying fragments. One of these fragments is plain list with a name of audio files when I click each line I'm playing the clicked audio files.
Everything works OK, but I would like to have some means of seeing a progress of the playback and ability to stop a playback, I was trying to add MediaController but even though I'm creating it without errors no media control is visible on a screen.
I'm not sure if I'm doing it in a correct way any help you would be appreciated.
Thanks a lot,
Radek
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
try {
if(convertView == null){
convertView = layoutInflater.inflate(R.layout.audio_row,parent,false);
}
TextView textView = (TextView) convertView.findViewById(R.id.rowText);
textView.setText("" + jsonAudio.getJSONObject(position).getString("description"));
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
String audioFileName = jsonAudio.getJSONObject(position).getString("file");
Toast.makeText(context, "audio item clicked: " + audioFileName, Toast.LENGTH_SHORT).show();
AssetFileDescriptor descriptor = context.getAssets().openFd(audioFileName);
long start = descriptor.getStartOffset();
long end = descriptor.getLength();
MediaPlayer mediaPlayer=new MediaPlayer();
mediaPlayer.setDataSource(descriptor.getFileDescriptor(), start, end);
mediaPlayer.prepare();
// not doing really anything
MediaController mediaController = new MediaController(context);
mediaController.setAnchorView(v);
mediaPlayer.start();
} catch (Exception e) {
e.printStackTrace();
}
}
});

Please check the below code for your refrence
In your code you have passed the TextView in the mediaController need to pass the SurfaceView instead of TextView and you need to set the MediaPlayer in the MediaController

Including .mp3 files in .apk

I'm currently working on Media Player. All is done except that i have .mp3 files in android emulator external storage. What i want to know is, how can i include all those .mp3 files to the .apk so that when i install the the app on phone, the files automatically transfer either on internal or external storage of the device.
I've gone through this issue but couldn't find best possible answer anywhere.
Please help me!

just copy your .mp3 files into res/raw folder and read them
mp = MediaPlayer.create(context, R.raw.fileName);

Android Media Playback Service Pause/Play

I'm not very experienced in Android, but I'm trying to make a Media Playback Service. My Start and Stop are working, but Pause/Play aren't. I've tried many different ways, but always unsuccessful.
When I pause and press play again, it starts from 0 or give me an error:
11-02 18:50:57.971 2043-2043/? E/MediaPlayer﹕ start called in state 2
11-02 18:50:57.971 2043-2043/? E/MediaPlayer﹕ error (-38, 0)

please add the crash report
