mp.stop() problem
I am new to android,actually this is my second program.I am programming from last night and i am trying to find a solution for hours!!!I read everything here and i google my problem but i still cant fix it!! My problem is the usual as i understood that i cannot stop audio playback when i click another button.I tried mp.release,stop,everything but keeps crashing when i press stop button or back!!What i am doing wrong??I have 22 buttons and i play 21 songs(one button at top for stop). Also i forgot to mention that i tried to make button when clicking 2nd time to stop playing but i couldn't do it that's why i put stop button.

I believe
public void onClick(View v)
{
MediaPlayer mp = MediaPlayer.create(getBaseContext(),R.raw.song21);
mp.start();
}
should be
public void onClick(View v)
{
mp = MediaPlayer.create(getBaseContext(),R.raw.song21);
mp.start();
}
The code you have posted is wrong, you are creating local MediaPlayer objects in each click handler. Use the object declared as a member of the activity instead, and then, when you call the stop method the reference will be established correctly.
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
MediaPlayer mp = MediaPlayer.create(getBaseContext(),R.raw.song1);
mp.start();
}
});
should be:
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mp = MediaPlayer.create(getBaseContext(),R.raw.song1);
mp.start();
}
});
