This is the code am using to fetch a file name(.mp3) dynamically from some other class as am having many mp3 files in my assets folder:
playAudioButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v)
{
FileName audio=new FileName();
String audioName=audio.getAudioName(count).toString();
if(audioName=="NO Audio")
{
Toast.makeText(getApplicationContext(), "No Audio for this page", Toast.LENGTH_SHORT).show();
}
else
{
try {
afd=getAssets().openFd(audioName + ".mp3");
mp = new MediaPlayer();
mp.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
mp.prepareAsync();
mp.start();
} 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();
}
}
}
});
}

Points to be noted: 1. I have checked similar threads on stack overflow the answer is using prepareAsync() 2. I have used prepareAsync()
Thanks in advance.
You can also use below onPrepared()
method to call start method so that start()
is called after MediaPlayer
is prepared.
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.start();
}
});
