问题
I'm trying to build an app where a piece of Music is played whenever the onCreate() is called, and I want for this music to be played throughout the whole app ie across Activities. what I've done so far is to create a Thread,within the OnCreate(), and I called it backgroundMusic, inside of it I created A MediaPlayer Object from a music piece in my Raw Folder. given that the music itself only runs for a minute or so and the average time spent on the app is more, I made a while Loop that as long as the app is running checks if the music is playing, if not then call start();
backgroundMusic = new Thread(new Runnable() {
@Override
public void run() {
while ( appIsRunning ){
if( ! music.isPlaying () ){
music.start();
}
}
}
});backgroundMusic.start();
the code runs just fine, however I did notice some Lag especially later when some other Threads and Images gets loaded.what I want to ask, is this an appropriate way to play background Music? is there a better more efficient way of doing that? also, how do I make the music stop as the app closes?

No, you need to declare music on a service. A service :
Will be independent of activity LifeCycle hence music will keep playing when Activity is closed
can be paused when needed like incoming call
Here is something to get you started. Happy coding!
