Develop Reference

Android is hanging when I press button to play music in second time

I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}

In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}

use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}

This is an AUDIO activity that works fine and it allows you to upload songs with a spinner.

How to start MediaPlayer after it has been stopped in android

I am new to Android and in my app I am working with MediaPlayer.
When I first tap the start button, the song plays, but when I tap the stop button and then I tap on the start button again, the song does not start playing again. Here's what I have so far:
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.stop();
}
});
}
}

Try this :
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.stop();
mp.release();
}
}
});

just check like this way
if(mdpl.isPlaying()){
mdpl.pause();
} else {
mdpl.start();
}

You can not call start, it media player in on stop state. Take a look on the state diagram of media player MediaPlayer state diagram.
When you call stop, you have to call release(), and with start you get a new media player, or just call reset.

try this
public void onStopBtnClick(View view) {
if (mAudioHelper != null) {
mAudioHelper.stop();
displayMessage("Stopping!");
}
}

Here is code to set sound file.
if (mPlayer != null) {
mPlayer.stop();
mPlayer.release();
}
mPlayer = new MediaPlayer();
AppLog.d("Created new Media player");
try {
mPlayer.setDataSource(fileName);
} catch (IOException e) {
AppLog.e("Can't open " + fileName + " file", e);
}
Before playing u should call the mPlayer.prepareAsync() function.
if you want to pause/play you have to use this code:
if (mediaPlayer.isPlaying()){
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
If you want to stop player use this:
if (mPlayer != null){
mPlayer.stop();
mPlayer.release();
}
mPlayer = null;
If you want to start song again use first functions and next with this steps

This code may help you..
#Override
protected void onDestroy() {
super.onDestroy();
destroyMediaPlayer();
}
private void destroyMediaPlayer() {
if (mediaPlayer != null) {
try {
mediaPlayer.release();
Log.d("here", "destroy");
} catch (Exception e) {
e.printStackTrace();
}
}
}

SOLUTION 1
for this solution, I took some info from here
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
MediaPlayer mp;
/**
* remain false till media is not completed, inside OnCompletionListener make it true.
*/
private boolean initialStage = true;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (initialStage) {
mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
new Player()
.execute("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} else {
if (mp && !mp.isPlaying())
mp.start();
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp && mp.isPlaying())
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
mp.release();
mp = null;
initialStage = true;
}
}
});
}
/**
* preparing mediaplayer will take sometime to buffer the content so prepare it inside the background thread and starting it on UI thread.
* #author piyush

*/
class Player extends AsyncTask<String, Void, Boolean> {
private ProgressDialog progress;
#Override
protected Boolean doInBackground(String... params) {
// TODO Auto-generated method stub
Boolean prepared;
try {
mp.setDataSource(params[0]);
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
initialStage = true;
mp.stop();
mp.reset();
}
});
mp.prepare();
prepared = true;
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
Log.d("IllegarArgument", e.getMessage());
prepared = false;
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
}
return prepared;
}
#Override
protected void onPostExecute(Boolean result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if (progress.isShowing()) {
progress.cancel();
}
Log.d("Prepared", "//" + result);
mp.start();
initialStage = false;
}
public Player() {
progress = new ProgressDialog(PlayngUrlFiles.this);
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
this.progress.setMessage("Buffering...");
this.progress.show();
}
}
}
SOLUTION 2
in order to avoid data downloding, try this
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
boolean prepared;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
prepared = false;
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
prepared = true;
mp.start();
}
});
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
try {
if(!prepared) {
mp.prepareAsync();
prepared = true;
} else {
mp.start();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.pause();
}
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
prepared = false;
}
}
});
}
}

#MRodrigues was right about media player states. But instead of calling release() after stop, Modify your code as below.
Currently,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
modify to,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!mp.isPlaying()) {
mp.prepare();
}
mp.start();
}
});

how to pause media player sound in android

I have media player in main activity. And sound start with this activity. I want when new activity start audio stop and when I press back from next activity and back to main activity audio starts. Please help me.
Code-
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mp = MediaPlayer.create(this, R.raw.test);
mp.start();
mp.setLooping(true);
addListenerOnButton();
}
public void addListenerOnButton()
{
boy1 = (Button) findViewById(R.id.boy1);
boy1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
mp.stop();
startActivity(new Intent(Main.this, Boy1.class));
}
});
}
#Override
protected void onPause() {
super.onPause();
mp.stop();
}
#Override
public void onBackPressed() {
super.onBackPressed();
mp.stop();
finish();
}
#Override
public void onResume()
{
super.onResume();
}
#Override
protected void onStop() {
super.onStop();
mp.stop();
}
}

try this way:onPause()
#Override
protected void onPause() {
super.onPause();
try{
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
}
}catch(Exception we){
we.printStackTrace();
}
}
And onResume()
#Override
protected void onResume() {
super.onResume();
try{
mediaPlayer.start();
}catch(Exception we){
we.printStackTrace();
}
}

You could use the pause() method available in MediaPlayer class. This would be useful:
http://developer.android.com/reference/android/media/MediaPlayer.html

You can do this using mediaPlayer.pause();

Streaming MediaPlayer will not work with Samsung Galaxy S3

Streaming MediaPlayer not working on Samsung galaxy s3. Don't have device myself but getting reports of it not working. Also tried Remote Test Lab and does not work. I have tested on many other devices and all work excepted for s3. Any help would be awesome!
Code:
public class Radio extends Activity {
private MediaPlayer mp;
private ImageButton pauseicon;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.player_1);
Toast.makeText(this, "Just one moment please", Toast.LENGTH_LONG).show();
pauseicon = (ImageButton) findViewById(R.id.pauseicon);
getActionBar().setDisplayHomeAsUpEnabled(true);
/**
* Play button click event plays a song and changes button to pause
* image pauses a song and changes button to play image
* */
String res = "http://************";
mp = new MediaPlayer();
try {
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setDataSource(res);
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer player) {
mp.start();
}
});
mp.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
}
pauseicon.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
// No need to check if it is pauseicon
if (mp.isPlaying()) {
mp.pause();
((ImageButton) v).setImageResource(R.drawable.playicon);
} else {
mp.start();
((ImageButton) v).setImageResource(R.drawable.pauseicon);
}
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
if (mp != null)
if (mp.isPlaying())
mp.stop();
mp.release();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onBackPressed() {
if (mp != null) {
if (mp.isPlaying())
mp.stop();
mp.release();
}
// there is no reason to call super.finish(); here
// call super.onBackPressed(); and it will finish that activity for you
super.onBackPressed();
}
}

This is what I do to get a streaming music to play, just tested this on a Samsung Galaxy SIII and it is working fine. The audio stream in this is a public university radio stream. But this should work with other online streams. Just make sure you enable the internet permissions in your manifest.
public class MainActivity extends Activity {
MediaPlayer mpMediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try{
mpMediaPlayer = new MediaPlayer();
mpMediaPlayer.setDataSource("http://streams.tsc.usu.edu:8888");
mpMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mpMediaPlayer.prepare();
mpMediaPlayer.start();
}catch(Exception e){
e.printStackTrace();
}
}

This might be a little late, but for those who are coming to this looking for this answer, one solution might be to implement the MediaPlayer.OnPreparedListener.
public class MyActivity extends Activity implements MediaPlayer.OnPreparedListener
MediaPlayer mpMediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
try{
mpMediaPlayer = new MediaPlayer();
mpMediaPlayer.setDataSource("audio url");
mpMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mpMediaPlayer.prepare();
mpMediaPlayer.setOnPreparedListener(this);
}catch(Exception e){
e.printStackTrace();
Log.e(TAG, "Error loading media");
}
}
#Override
public void onPrepared(MediaPlayer mp) {
mpMediaPlayer.start();
}

sound doesn't stop when the user press back key

I'm newbie in android programming. I have the following code with a mediaplayer. when the user presses the back key or goes to another activity the sound won't stop.
what's the problem? I have the onDestory method but my problem exists!
public class Elementary1Activity extends Activity implements Runnable, OnClickListener, OnSeekBarChangeListener{
private SeekBar seekBar;
private ImageButton startMedia;
private ImageButton pauseMedia;
private MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.elementary1);
AudioControl();
}
public void AudioControl(){
seekBar = (SeekBar) findViewById(R.id.seekBarnew2);
startMedia = (ImageButton) findViewById(R.id.playbuttonnew2);
pauseMedia = (ImageButton) findViewById(R.id.pausebuttonnew2);
seekBar.setOnSeekBarChangeListener(this);
startMedia.setOnClickListener(this);
pauseMedia.setOnClickListener(this);
}
public void run() {
int currentPosition= 0;
int total = mp.getDuration();
while (mp!=null && currentPosition<total) {
try {
Thread.sleep(1000);
currentPosition= mp.getCurrentPosition();
} catch (InterruptedException e) {
return;
} catch (Exception e) {
return;
}
seekBar.setProgress(currentPosition);
}
}
public void onClick(View v) {
pauseMedia.setVisibility(View.VISIBLE);
seekBar.setVisibility(View.VISIBLE);
startMedia.setVisibility(View.INVISIBLE);
if (v.equals(startMedia)) {
if (mp != null && mp.isPlaying()) return;
if(seekBar.getProgress() > 0) {
mp.start();
return;
}
mp = MediaPlayer.create(Elementary1Activity.this, R.raw.e1);
mp.start();
seekBar.setProgress(0);
seekBar.setMax(mp.getDuration());
new Thread(this).start();
}
if (v.equals(pauseMedia) && mp!=null) {
mp.pause();
pauseMedia.setVisibility(View.INVISIBLE);
startMedia.setVisibility(View.VISIBLE);
}
}
#Override
public void onDestroy() {
super.onStop();
mp= MediaPlayer.create(Elementary1Activity.this,R.raw.e1);
if(mp.isPlaying())
{
mp.stop();
mp.release();
finish();
}
}
public void onStartTrackingTouch(SeekBar seekBar) {
}
public void onStopTrackingTouch(SeekBar seekBar) {
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
if(fromUser) mp.seekTo(progress);
}
}

I'd use onPause() event in your Elementary1Activity to manage the music pausing.
Something like:
#Override
public void onPause() {
super.onPause();
if (mp!=null) {
mp.pause();
}
}

You can do two things. If you want that MediaPlayer stop when you push back button and you want to close the app the best option is:
#Override
public void onDestroy(){
if(mp != null){
if(mp.isPlaying()){
mp.stop
}
mp.release();
}
super.onDestroy();
}
And if you want to make that MediaPlayer stop when you change of activity:
#Override
public void onPause(){
if (mp != null && mp.isPlaying()){
mp.pause();
}
}
Apart of that, don't create a new MediaPlayer when you want to close your app.
