I have a ListView with some items and each item plays a certain sound. This is the code:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
try {
player.setDataSource(externalStoragePath + "/Android/data/com.whizzappseasyvoicenotepad/" + recordedFilesArray.get(arg2) + ".mp3");
player.prepare();
player.start();
} 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 I click an item and it starts playing and then click another item before the one I clicked before has finished playing, the MediaPlayer will just play both sounds at the same time. How do I get my MediaPlayer to stop() playing the previous sound and start playing the new sound if I have clicked the item before it stopped playing?
I tried adding player.Stop() before try, so that everytime I click an item, the MediaPlayer stops before setting a new source and starting again, but that just stops the previous sound and won't play the new sound.
I also tried adding IF statement, like this:
if (!player.isPlaying()){
//normally start the player
}
else if (player.isPlaying()){
//stop it before starting it again
}
I'd copy my actual code but I already deleted it since it didn't work. It also just stopped the previous sound and didn't play the new one.
Reset your player after stopping song.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
try {
if (player!=null && player.isPlaying())
{
player.stop();
player.reset();
}
player.setDataSource(externalStoragePath + "/Android/data/com.whizzappseasyvoicenotepad/" + recordedFilesArray.get(arg2) + ".mp3");
player.prepare();
player.start();
} 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();
}
}
});
You have to call setDataSource() in the idle state. So you have to call reset() before calling setDateSource()
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
try {
player.reset();
player.setDataSource(externalStoragePath + "/Android/data/com.whizzappseasyvoicenotepad/" + recordedFilesArray.get(arg2) + ".mp3");
player.prepare();
player.start();
} 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();
}
}
});
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
try {
stopPlaying();
initializeMediaPlayer(externalStoragePath + "/Android/data/com.whizzappseasyvoicenotepad/" + recordedFilesArray.get(arg2) + ".mp3");
startPlaying();
} 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();
}
}
});
private void stopPlaying() {
if (player!=null && player.isPlaying()) {
player.stop();
player.release();
}
}
private void initializeMediaPlayer(String path) {
player = new MediaPlayer();
try {
player.setDataSource(path);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private void startPlaying() {
try {
player.prepareAsync();
player.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
if(player!=null)
player.start();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
to reuse MediaPlayer, you must call reset() before setting new dataSource. One more thing, you should not call prepare() in UI thread, it may cause ANR error. You would rather call prepareAsync() function.

I get the above error when trying to play audio, any ideas why I get this error, the same code works in some places, I'm calling the static function from a fragment?

final MediaPlayer mp;
try {
AssetFileDescriptor fileDescriptor =
context.getAssets().openFd(aud);
mp = new MediaPlayer();
mp.setDataSource(fileDescriptor.getFileDescriptor(),
fileDescriptor.getStartOffset(),
fileDescriptor.getLength());
fileDescriptor.close();
mp.prepare();
mp.start();
} catch (IllegalArgumentException e) {

Let me know if this helped -
public class MainActivity extends AppCompatActivity implements MediaPlayer.OnPreparedListener,AudioManager.OnAudioFocusChangeListener{
MediaPlayer mp;
AudioManager mAudioManager ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int result = mAudioManager.requestAudioFocus(this, AudioManager.STREAM_MUSIC,
AudioManager.AUDIOFOCUS_GAIN);
if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
//got audio focus
playAudio("bell.mp3",this);
}
}
private void playAudio(String aud, Context context) {
try {
AssetFileDescriptor fileDescriptor =
context.getAssets().openFd(aud);
mp = new MediaPlayer();
mp.setDataSource(fileDescriptor.getFileDescriptor(),
fileDescriptor.getStartOffset(),
fileDescriptor.getLength());
fileDescriptor.close();
mp.prepareAsync();
mp.setOnPreparedListener(this);
} 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();
}
}
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mp.start();
}
#Override
public void onAudioFocusChange(int i) {
}
}
Here, I am first trying to get the audio focus and then letting the mediaplayer do the task asynchronously.
I have an App that is receiving a video file from another App that is working as a Server. While the App is saving the file received on the socket, the video stream starts playing the file (which is under construction). In the code sample, after I press the btnStream, I press the btnPlay and App runs successfully. However, if the playing rate is greater than the download rate, an error will occur. I want to avoid this case. So I need to have a listener on the Video Playing that will pause the videoview when it predicts that this error will occur. I know a solution where if I know the video size, I can counter the bytes received and monitor how many seconds have been buffered and see if the videoview should pause or not. However, is it possible to do it without knowing the video file size? Or having two threads that depends on each other? Thanks.
Note: the VideoView used is a custom one where it can play FileDescriptor.
btnStream.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub

I applied a simple solution that resolved the problem. I am sharing it if anyone is having the same problem. The solution was simply to add an error listener to the videoView that will block the error popups and pauses the video.
mVideoView.setOnErrorListener(new OnErrorListener(){
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
statusText.setText("ERROR PLAYING VIDEO");
mVideoView.pause();
return true;
}
});
pDialog = new ProgressDialog(PlayVideoActivity.this);
pDialog.setTitle("Gajacharitra");
pDialog.setMessage("Buffering video...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
try {
// Start the MediaController
mediacontroller.setAnchorView(mVideoView);
// Get the URL from String VideoURL
Uri video = Uri.parse(mVideoURL);
mVideoView.setMediaController(mediacontroller);
mVideoView.setVideoURI(video);
mVideoView.requestFocus();
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
pDialog.dismiss();
mVideoView.start();
}
});
mVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
mVideoView.pause();
pDialog.dismiss();
Toast.makeText(PlayVideoActivity.this, "Can't play this video.", Toast.LENGTH_LONG).show();
finish();
return true;
}
});
} catch (Exception e) {
/*Log.e("Error", e.getMessage());
e.printStackTrace();*/
pDialog.dismiss();
Toast.makeText(PlayVideoActivity.this, "Can't play this video.", Toast.LENGTH_LONG).show();
finish();
}
I have a problem, I have a for loop and a ProgressDialog and would like to see something like (10/5) where 10 is the total items to be processed by and for the 5 elements are currently being developed. I have this code.
new Thread(new Runnable() {
public void run() {
for(int i=0; i<adapter.getTotalItems().size(); i++) {
try {
index = i;
progressDialog = ProgressDialog.show(MyClass.this,adapter.getTotalItems().size()+"/"+index, );
MyClass.this.runOnUiThread(new Runnable() {
public void run() {
progressDialog.cancel();
}
});
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
Thread.sleep(1*2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
MyClass.this.runOnUiThread(new Runnable() {
public void run() {
progressDialog.dismiss();
}
});
}
}).start();
Don´t cancle the ProgressDialog every Time, just Change the Title like:
mProgressDialog.setTile(adapter.getTotalItems().size()+"/"+index);
That´s it.
got my code working. Just having a little trouble with one part.
public void picksound(){
Intent mIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(mIntent, 1);
}

if (resultCode == RESULT_OK && null != mIntent) {
if (requestCode == 1) {
Uri selectedRing = mIntent.getData();
}
}}
private void playSong(String selectedRing){
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(selectedRing);
} 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

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
}
public void alarmmsg(){
//ringtone player
playSong(selectedRing);
//
So that's the code I am working with. When I try to call the playSong function, I am asked for a string, and the only string it seems to accept is "null". Can someone help to see what I've done wrong?
Try changing this line :
MediaPlayer mp = new MediaPlayer();
To this:
MediaPlayer player = MediaPlayer.create(this, Uri.parse("http://www.urltofile.com/file.mp3"));
I am looking to start a Service to keep music playing from my app when the user closes it. I have done a lot of searching around and all I am really looking for is a simple example that will allow me to start the service and music when the user presses a button. And when the user comes back to the app at some other point and presses another button then I want to bind to the service and stop the music playback. I have done a lot of searching around and I was hoping that someone could give me a clear explanation of how this all works and maybe even a code example.
to play song in Sd card using this snippet code:
public void playSong(int songIndex) {
// Play song
try {
mp.reset();
mp.setDataSource(songsListingSD.get(songIndex).get("songPath"));
mp.prepare();
mp.start();
// Displaying Song title
String songTitle = songsListingSD.get(songIndex).get("songTitle");
songTitleLabel.get().setText(songTitle);
// Changing Button Image to pause image
btnPlay.get().setImageResource(R.drawable.ic_media_pause);
// set Progress bar values
songProgressBar.get().setProgress(0);
songProgressBar.get().setMax(100);
// Updating progress bar
updateProgressBar();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
