I am trying to run audios one after another with a time gap of 5 seconds. However I dont really see that happening. My third audio in the list is played and others are skipped. This means while debugging only music3 is being played and others are not. I would love alternate methods of doing this. Moreover I used prepare method just like that. Makes no difference while running though.
for(int j=0;j<3;j++)
{
if(j==0)
{
xnp = MediaPlayer.create(this,R.raw.ticktock);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
try {
xnp.prepare();
xnp.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}, 5000);
xnp.stop();
}
if(j==1)
{
xnp = MediaPlayer.create(this,R.raw.music2);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
try {
xnp.prepare();
xnp.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}, 5000);
xnp.stop();
}
else if (j==2)
{
xnp = MediaPlayer.create(this,R.raw.music3);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
try {
xnp.prepare();
xnp.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}, 5000);
xnp.stop();
intenter();
}
}
Your current implementation does not work because the media playback is not done on the main thread, so you are immediately playing all 3 media resources, so only the third one is heard.
I think you might want to call MediaPlayer#setOnCompletionListener on your MediaPlayer object. In the completion listener, you can then postDelayed onto your Handler to queue up the next resource to play.

I am using a TextureView to play a video in a ListView. The TextureView itself works perfectly, however, if I press the home button and reenter the application a few times, the TextureView turns black (though the audio continues to play). If I exit and reenter again, the TextureView turns white (or maybe transparent, as white is the colour of my background).
Here is my code:
holder.instagramTextureView
.setSurfaceTextureListener(new SurfaceTextureListener() {
#Override
public void onSurfaceTextureUpdated(
SurfaceTexture surface) {
// TODO Auto-generated method stub
}
#Override
public void onSurfaceTextureSizeChanged(
SurfaceTexture surface, int width, int height) {
// TODO Auto-generated method stub
}
#Override
public boolean onSurfaceTextureDestroyed(
SurfaceTexture surface) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onSurfaceTextureAvailable(
SurfaceTexture surface, int width, int height) {
final Surface s = new Surface(surface);
try {
holder.mMediaPlayer = new MediaPlayer();
holder.mMediaPlayer.setDataSource(post
.getMedias().get(0)
.getMediaUrlVideomp4StandardRes());
holder.mMediaPlayer.setSurface(s);
holder.mMediaPlayer.prepare();
holder.instagramVideoVolume = 0f;
holder.mMediaPlayer.setVolume(
holder.instagramVideoVolume,
holder.instagramVideoVolume);
//holder.mMediaPlayer.setOnBufferingUpdateListener(this);
holder.mMediaPlayer
.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(
MediaPlayer mp) {
// To play:
mp.reset();
try {
mp.setDataSource(post
.getMedias()
.get(0)
.getMediaUrlVideomp4StandardRes());
mp.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch

e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch

e.printStackTrace();
} catch (IllegalStateException e) {

} catch (IOException e) {
// TODO Auto-generated catch

e.printStackTrace();
}
// <--- Here comes a call to
// "To Resize" which is shown
// right above this code
mp.start();
}
});
// holder.mMediaPlayer.setOnPreparedListener(this);
//holder.mMediaPlayer.setOnVideoSizeChangedListener(this);
holder.mMediaPlayer
.setAudioStreamType(AudioManager.STREAM_MUSIC);
holder.mMediaPlayer.start();
holder.instagramTextureView
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (holder.instagramVideoVolume == 1) {
holder.instagramVideoVolume = 0f;
holder.mMediaPlayer
.setVolume(
holder.instagramVideoVolume,
holder.instagramVideoVolume);
} else {
holder.instagramVideoVolume = 1f;
holder.mMediaPlayer

Problem was making a new mediaplayer each time the surface is available. Not quite sure how this worked, but this was the problem. Instead, I create the mediaplayer outside of this listener.
From my research, textureView.getSurfaceTexture() returns null onResume(). What I did was reattach a listener to it in onResume().
TextureView textureView;
/*....
Usual stuff
*/
public void onPause(){
super.onPause();
//... destroy or disable image producer
}
public void onResume(){
super.onResume();
textureView.setSurfaceTextureListener(/*another listener*/);
}
Then, perform your usual things on onSurfaceTextureAvailable()
The black screen and audio playing happened with me when I did not release the MediaPlayer object.
I'm loading audio sounds into a listview, I play them.When the audio playing is done, i want to change that specific sound's pause button to play button again.
here is my code to play sounds
soundChild.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
player.setDataSource(url);
// file.close();
player.prepare();
player.setLooping(false);
// player.start();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (player.isPlaying()) {
if (player != null) {
player.pause();
// Changing button image to play button
soundChild.setImageResource(R.drawable.playbutton);
}
} else {
// Resume song
if (player != null) {
player.start();
// Changing button image to pause button
soundChild.setImageResource(R.drawable.pausebutton);
}
}
}
});
player.setOnCompletionListener(new OnCompletionListener() {
#Override public void onCompletion(MediaPlayer mp) { // TODO
// Auto-generated method stub player.release(); player=null;
Toast.makeText(_context, "complete", Toast.LENGTH_LONG).show();
soundChild.setImageResource(R.drawable.playbutton);
player.reset();
} });
But on complete listner the imageview of player button is never changed back to play imageview again. I doin't know where i'm doing wrong, because if onComplete is being called then imageview background should also change.please help.
Usually You have to call requestLayout before:
soundChild.requestLayout();
soundChild.setImageResource(R.drawable.playbutton);
and then after changing the image
soundChild.invalidate();
What else could You try? If it doesn´t work, You can also try:
soundChild.setImageDrawable(context.getResources().getDrawable(R.drawable.playbutton));
Because, like described in the API for setImageResource:
This does Bitmap reading and decoding on the UI thread, which can
cause a latency hiccup
Also, what it is possible, You have to call it in on ui thread:
runOnUiThread(new Runnable() {
#Override
public void run() {
soundChild.setImageResource(R.drawable.playbutton);
}
});
and call this in onCompletion.
Require develop streaming audio playback with mediaplayer on android.
Any ideas ?!
Thanks
I try the following code:
play.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String url = "http://stream.radiosai.net:8002/"; // your URL here
MP.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
MP.setDataSource(url);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MP.prepareAsync();
MP.start();
}
});
The above does not work Error deploying
MP.start();
Should be called after the mediaplager is ready, in setOnPreparedListener.
When you create MediaPlayer object, add prepared listener
MP.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
The German computer magazine C't recently published an article with the source code for an Android alarm clock radio. You can download the project files here. I think this contains everything that you need.
I am doing an radio streaming app. I am trying to display some loading bar frame by frame animation before my stream begins. but the animations starts after playing the stream only. How could i show my anim before stream loads. Here is my code snippet. Help is appreciated...
bhajan_play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo Info = conMan.getActiveNetworkInfo();
if (Info == null) {
Toast.makeText(BhajanStream.this, "POOR SIGNALS ",
Toast.LENGTH_LONG).show();
// startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
}
else {
loadanim.setBackgroundResource(R.drawable.loader_1);
loadanim.setBackgroundResource(R.anim.loadanim);
loadanimation = (AnimationDrawable) loadanim
.getBackground();
loadanimation.isVisible();
effectanim.setBackgroundResource(R.drawable.effect_1);
effectanim.setBackgroundResource(R.anim.musiceffect);
effectanimation = (AnimationDrawable) effectanim
.getBackground();
bhajan_play.setBackgroundResource(R.drawable.bhajan_start);
bhajan_play.setVisibility(View.GONE);
bhajan_stop.setVisibility(View.VISIBLE);
loadanim.setVisibility(View.VISIBLE);
effectanim.setVisibility(View.VISIBLE);
}
try {
mediaPlayer.reset();
mediaPlayer.setDataSource(rs_bhajan_uri);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
}
});
}
protected void onPreExecute() {
// UI work allowed here
loadanimation.start();
}
You should call prepareAsync() rather than just prepare().
From the MediaPlayer documentation:
For streams, you should call prepareAsync(), which returns
immediately, rather than blocking until enough data has been buffered.
(Calling prepare will block your Ui Thread until the data is prepared, meaning that updating your views has to wait until the preparation is done)
Example implementation:
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
I'm trying to get this to work the way I want and it just won't I think I had it at some point but I was trying to fix something else and changed a few things and messed it up. Basically I'm this button is a play button. It is supposed to run media player through another thread so that it reacts and buffers faster. Issue is after it plays through to the end and I click play it is ended and keeps running the onCompletion. When I would like it to start over and play from the beginning again.
public void onClick(View v) {
if(playClick%2==0){
song1.setBackgroundResource(R.drawable.button_pause);
try{
if(playClick==0){
playThread();
if(lastPlayedExists){
lastPlayed.release();
}
}
mp.start();
mpExists = true;
playClick++;
lastPlayed = mp;
lastPlayedExists=true;
mp.setOnCompletionListener(new OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer media) {
mp.reset();
song1.setBackgroundResource(R.drawable.button_play);
}
});
}catch (NullPointerException e){
}
}
else if (playClick%2==1){
song1.setBackgroundResource(R.drawable.button_play);
mp.pause();
playClick++;
}
}
}
});
And this is the thread for media player
private void playThread(){
try{
new Thread(new Runnable() {
public void run() {
try {
mp.setDataSource(song);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}catch(IllegalStateException e){
}
}
I have tried it with the onCompletion having mp.reset(), mp.stop(), and mp.release() along with trying lastPlayed.release() all in different tests. As well as none of them being there and it just being the button change and the progress bar reset. If you know how to fix this and make it replay as it should I would greatly appreciate it. Or if you know how to make the thread stop and restart some how so that I can just make it recall and do the thread over again that would work too (atm when that has been tried it crashes because the thread has already been started). Thanks and I appreciate any input.
mp.setOnCompletionListener(new OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer media) {
playClick=2;
song1.setBackgroundResource(R.drawable.button_play);
}
});
