At the very start of my Main activity, I call on the Media Player to play a song
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ourSurfaceView = new MyBringBack(this);
ourSurfaceView.setOnTouchListener(this);
Context ctx;
firstRun = 0;
MediaPlayer ourSong = MediaPlayer.create(MainActivity.this, R.raw.music);
ourSong.setLooping(true);
ourSong.start();
However, when I open an activity, it doesn't stop. The next time I start an activity, it doesn't stop. But the third time I do, it does. Here is the code to make the intent to the third activity:
(I used a ViewPager for this)
public void fiveGames(View view){
Intent i = new Intent(this, WhichNormalLevelActivity.class);
i.putExtra("uh", 1);
startActivity(i);
finish();
}
Here is the code for the activity that is created.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_which_normal_level);
ctx = this;
box = (TextView)findViewById(R.id.box_button);

Any ideas as to why it stops playing music?
Thanks :)
You create your MediaPlayer like this:
MediaPlayer ourSong = MediaPlayer.create(MainActivity.this, R.raw.music);
You are passing the instance of MainActivity as the Context parameter. This will link the MediaPlayer lifecycle to the lifecycle of MainActivity.
When you launch WhichNormalLevelActivity, like this:
public void fiveGames(View view){
Intent i = new Intent(this, WhichNormalLevelActivity.class);
i.putExtra("uh", 1);
startActivity(i);
finish();
}
you call finish() on MainActivity. Android will clean up and destroy anything that has a lifecycle linked to MainActivity, including, in your case, your MediaPlayer.
If you want your MediaPlayer lifecycle to be independent of a specific Activity, pass the global application context as the Context parameter when creating the MediaPlayer. To get the global context, call getApplicationContext(). Just don't forget to shut it down and free the resources when you are done with it!
