I'm trying to use the same media player but change the data source. Here is what I'm trying to do:
private MediaPlayer mMediaPlayer;
public void pickFile1() {
initMediaPlayer("myfile1.mp3");
}
public void pickFile2() {
initMediaPlayer("myfile2.mp3");
}
private void initMediaPlayer(String mediafile) {
// Setup media player, but don't start until user clicks button!
try {
if (mMediaPlayer == null) {
mMediaPlayer = new MediaPlayer();
} else {
mMediaPlayer.reset(); // so can change data source etc.
}
mMediaPlayer.setOnErrorListener(this);
AssetFileDescriptor afd = getAssets().openFd(mediafile);
mMediaPlayer.setDataSource(afd.getFileDescriptor());
}
catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException: " + e.getMessage());
}
catch (IOException e) {
Log.d(TAG, "IOException: " + e.getMessage());
}
catch (IllegalArgumentException e) {
Log.d(TAG, "IllegalArgumentException: " + e.getMessage());
}
catch (SecurityException e) {
Log.d(TAG, "SecurityException: " + e.getMessage());
}
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.prepareAsync(); // prepare async to not block main thread
mMediaPlayer.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK); // Keep playing when screen goes off!
}
I just call this when I want to change to a new mediafile. It doesn't appear to be changing the data source successfully though. First question: is it possible to do it this way, or do I have to release the media player and create a new one for each new file? If it is possible, then why isn't my code working right?
Edit: well, releasing and recreating the media player isn't doing it either! It just keeps playing the same song!?!? How is that even possible? New idea -- create a different media player for each track, is that really what I have to do here? Is this a bug in Android perhaps?
Prepare media file: To play a media file, you need to first prepare it i.e. you need to load the file for playback. Methods used for doing this are prepare(), prepareAsync(), and setDataSource(). Start/Pause the playback: After loading the media file, you can start playing the media file by using the start() method.
The MediaPlayer can be moved to the specific time position using seekTo() method so that the MediaPlayer instance can continue playing the Audio or Video playback from that specified position.
MediaPlayer class can be used to control playback of audio/video files and streams.
One of the most important components of the media framework is the MediaPlayer class. An object of this class can fetch, decode, and play both audio and video with minimal setup.
Make sure to stop and reset mediaplayer before changing datasource. On more important thing when you stop it calls
onCompletion
.. So do check what you are doing in this method. Then call
mplayer.setDataSource(audioPath);
mplayer.setOnPreparedListener(this);
mplayer.prepareAsync();
