How to make service for Play Pause of music Player

How to make service for Play Pause of music Player - android

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.

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

start/stop button radio stream service

I have the code of a radio stream app from this site radio stream example, but when i want to stop the stream it restarts. The only way to stop it is exit the app and get back to the app via the "recent apps" button or notification screen.
Can someone help me with the code?

The build() method was added in API level 16 (Android 4.1). You are probably trying to run your code on an older version of Android.
The getNotification() method is deprecated starting at API level 16, but is fine to use in older API levels >= 11.
Note: The entire Notification.Builder class was added in API level 11 (Honeycomb), so I assume that your app's minimum required API level is at least 11.
To fix your issue, you can use the following code.
Notification ya =

MediaPlayer android doesnt play

i use these lines to play some audio file with mediaplayer, both on a service and in an activity, yet there is no sound on my device, what could be the reason? and what should i try to do to understand whats wrong and finally fix that?
MediaPlayer mp = MediaPlayer.create(this, R.raw.alert);
mp.start();

Intent viewMediaIntent = new Intent();
viewMediaIntent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(objectFilePath);
viewMediaIntent.setDataAndType(Uri.fromFile(file), "audio/*");
viewMediaIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(viewMediaIntent);

Check out the state diagram in the MediaPlayer docs.
After you've created the MediaPlayer it is in the Idle state. As you can see, you need to initialize and prepare it before you call start().

Check the following code, it works fine for me. I hope it will work for you also.....Dont forget to add Audio PlayBack permission in android Manifest File
