I can not hear sound, even if I hit the volume up/down button on emulator.

However, I can hear the mp3 using other mp3 player on my system.

does anyone have any clue on that?

Thanks a lot in advance

I am using a MediaPlayer instance in order to stream audio files from an Internet location. The audio player is in a separate activity. The user can select from a list of audio files and come to this activity to play the audio.

Now the user might go back to the previous activity (with the list) and select another audio file. In this case, I want to stop any other audio that is playing and start playing the new audio which was selected.

I did find out how to know whether an audio is playing. We can do it by using an object of AudioManager and calling isAudioPlaying(). This will return a true if any audio is playing.

How do I stop an audio currently playing? I do not have an instance of the MediaPlayer object which was created to start the audio (coz the user has already left the activity once and has come back with a new object of the activity and thus a new instance of the MediaPlayer). Is there any way I can stop any audio playing without having to hold on to the MediaPlayer object?

Thanks.

E.g.:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

1. mediaplayer = MediaPlayer.create(MainActivity.getInstance(), R.raw.musicmp3);
2. try {
3.         mp.prepare();
4. } catch (IllegalStateException e) {
5.         e.printStackTrace();
6. } catch (IOException e) {
7.         e.printStackTrace();
8. }
9. mp.start();
10.  

Parsed in 0.030 seconds, using GeSHi 1.0.8.4

If I call mediaplayer.stop() the music is not stopped. Why that?






Thanks!

After stopping a song from playing, how do you restart the song? I click play again and it does not start. I have to exit and then restart to play.

thank you again.
