My android radio app automatically close when I click back button

My android radio app automatically close when I click back button - java

I am trying to run my Android radio app in the background. So when I click the back button after a little time it has been forced to stop. Automatically calls the onDestroy() method. How do I fix this problem?
This is the main activity class onBackPressed() button code.
#Override
public void onBackPressed(){
System.out.println("onBackPressed");
serviceIntent.addCategory(Intent.CATEGORY_HOME);
serviceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(serviceIntent);
moveTaskToBack(true);
//activity.moveTaskToBack(true);
}
This is the console log
> I/System.out: onPrepared I/System.out: onBackPressed I/System.out:

By design, all SpeechRecognizer's methods "must be invoked only from the main application thread."
Main application thread is also referred to as "UI thread".
This means that SpeechRecognizer cannot run in a service.

Using Background Music while playing game on Android app game

I am a newbie in Android Developer
I am building a game app on Android Studio. But, I have had a problem about Background music while playing game. I have used Bound Service to handle through the class: MusicService extends Service implements MediaPlayer.OnErrorListener. But, my App was stopped when I run.
I have tried to fixed and explored solutions, but, I can't run app...
This is source code:
MusicService.java
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnErrorListener;
import android.os.Binder;
import android.os.IBinder;
import android.widget.Toast;
public class MusicService extends Service implements MediaPlayer.OnErrorListener {
private final IBinder mBinder = new ServiceBinder();
MediaPlayer mPlayer;
private int length = 0;
public MediaPlayer Player;
public MusicService() {
}
public class ServiceBinder extends Binder {
public MusicService getService() {
return MusicService.this;
}
}
#Override
public IBinder onBind(Intent arg0) {
return mBinder;
}
#Override
public void onCreate() {
super.onCreate();
Player = MediaPlayer.create(this, R.raw.one);
mPlayer.setOnErrorListener(this);
if (mPlayer != null) {
mPlayer.setLooping(true);
mPlayer.setVolume(100, 100);
}
mPlayer.setOnErrorListener(new OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int
extra) {
onError(mPlayer, what, extra);
return true;
}
});
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mPlayer.start();
return START_STICKY;
}
public void pauseMusic() {
if (mPlayer.isPlaying()) {
mPlayer.pause();
length = mPlayer.getCurrentPosition();
}
}
public void resumeMusic() {
if (mPlayer.isPlaying() == false) {
mPlayer.seekTo(length);
mPlayer.start();
}
}
public void stopMusic() {
mPlayer.stop();
mPlayer.release();
mPlayer = null;
}
#Override
public void onDestroy() {
super.onDestroy();
if (mPlayer != null) {
try {
mPlayer.stop();
mPlayer.release();
} finally {
mPlayer = null;
}
}
}
public boolean onError(MediaPlayer mp, int what, int extra) {
Toast.makeText(this, "music player failed", Toast.LENGTH_SHORT).show();
if (mPlayer != null) {
try {
mPlayer.stop();
mPlayer.release();
} finally {
mPlayer = null;
}
}
return false;
}
}
and, MainActivity.java
public class MainActivity extends AppCompatActivity {
private boolean mIsBound = false;
private MusicService mServ;
private ServiceConnection Scon =new ServiceConnection(){
public void onServiceConnected(ComponentName name, IBinder service) {
MusicService.ServiceBinder binder = (MusicService.ServiceBinder)service;
mServ =binder.getService();
}
public void onServiceDisconnected(ComponentName name) {
mServ = null;
}
};
// Activity create UI its
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
// Activity start.
#Override
protected void onStart() {
super.onStart();
// create Intent for MusicService.
Intent intent = new Intent(MainActivity.this,MusicService.class);
// call method bindService(..) to bind activity
this.bindService(intent, Scon, Context.BIND_AUTO_CREATE);
}
//Activity stop
#Override
protected void onStop() {
super.onStop();
if (mIsBound) {
this.unbindService(Scon);
mIsBound = false;
}
}
Then, I didn't also forget add the code following in AndroidManifest
<service
android:name=".MusicService"
android:enabled="true"
android:exported="true"></service>
That's all problems mine. This makes me so confuse
Help you, please
Thank you very much

Can you add more log debug in logcat? Not sure but I guess problem is you call:
mPlayer.start();
in onStartComand(). Your service should implement MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener,MediaPlayer.OnCompletionListener and above function should be call in
void onPrepared(MediaPlayer mp)

Radio app into a service [closed]

Improve this question
Hi I was following a tutorial I found to make an app that plays a radio, the app works until you exit because then the sound stops. I have researched and found out that it needs to be a service but I am not sure how to change it to a service, this is the code I used.
import android.app.Activity;
import android.os.Bundle;
import java.io.IOException;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListener;
import android.media.MediaPlayer.OnPreparedListener;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
public class myMain extends Activity implements OnClickListener {
private ProgressBar playSeekBar;
private Button buttonPlay;
private Button buttonStopPlay;
private MediaPlayer player;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initializeUIElements();
initializeMediaPlayer();
}
private void initializeUIElements() {
playSeekBar = (ProgressBar) findViewById(R.id.progressBar1);
playSeekBar.setMax(100);
playSeekBar.setVisibility(View.INVISIBLE);
buttonPlay = (Button) findViewById(R.id.buttonPlay);
buttonPlay.setOnClickListener(this);
buttonStopPlay = (Button) findViewById(R.id.buttonStopPlay);
buttonStopPlay.setEnabled(false);
buttonStopPlay.setOnClickListener(this);
}
public void onClick(View v) {
if (v == buttonPlay) {
startPlaying();
} else if (v == buttonStopPlay) {
stopPlaying();
}
}
private void startPlaying() {
buttonStopPlay.setEnabled(true);
buttonPlay.setEnabled(false);
playSeekBar.setVisibility(View.VISIBLE);
player.prepareAsync();
player.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
player.start();
}
});
}
private void stopPlaying() {
if (player.isPlaying()) {
player.stop();
player.release();
initializeMediaPlayer();
}
buttonPlay.setEnabled(true);
buttonStopPlay.setEnabled(false);
playSeekBar.setVisibility(View.INVISIBLE);
}
private void initializeMediaPlayer() {
player = new MediaPlayer();
try {
player.setDataSource("stream url");
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
player.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {
public void onBufferingUpdate(MediaPlayer mp, int percent) {
playSeekBar.setSecondaryProgress(percent);
Log.i("Buffering", "" + percent);
}
});
}
#Override
protected void onPause() {
super.onPause();
if (player.isPlaying()) {
player.stop();
}
}
}
I tried changing it but I am not sure how to put the functions from the main activity into a new service and then run it.
public class MyService extends Service implements MediaPlayer.OnPreparedListener {
private static final String ACTION_PLAY = "com.example.action.PLAY";
MediaPlayer mMediaPlayer = null;
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mMediaPlayer = private void initializeMediaPlayer() {
player = new MediaPlayer();
try {
player.setDataSource("stream url");
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
player.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {
public void onBufferingUpdate(MediaPlayer mp, int percent) {
playSeekBar.setSecondaryProgress(percent);
Log.i("Buffering", "" + percent);
}
});
} // initialize it here
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.prepareAsync(); // prepare async to not block main thread
}
}
/** Called when MediaPlayer is ready */
public void onPrepared(MediaPlayer player) {
player.start();
}
}
I tried using the above code but I do not know how to start the action and whether or not it will work.
Thank you for reading :)

Call a service from your main activity.
startService(new Intent(MusicService.ACTION_PLAY));
your service class.
public class MusicService extends Service {
public static MediaPlayer mp;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
mp = new MediaPlayer();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
String action = intent.getAction();
if (action.equals(ACTION_PLAY))
processPlayRequest();
return START_STICKY;
}

Music player implementation

I am new to Android. I'm trying to create a music player which will play specific MP3 based on the count (controlled by Rc variable) and based on the button sequence (controlled by BitCount variable) should change. And I have one stop button by clicking which I should be able to stop the music.
My problem is everything is working fine when UI is on foreground but when screen goes to background then also music start running (it's OK let music be running on background) but when once again I bring my UI from background to foreground than by clicking stop button I am unable to stop the music, it runs continuously. This same problem is happening when I am rotating my mobile.

When you close your app, ur activity is destroyed and hence reference to ur media player variable is lost. When you recreate ur activity you get a new set of reference and hence ur unable to stop it.
You will have to create a Service name it as MediaPlayerService which will deal with all media related actions like play, pause etc..
You can read about service over here:
http://developer.android.com/guide/components/services.html
If you want an example for media player, you can check RandomMusicPlayer, an excellent media player example provided by android in android sample projects.
