Question

Is it possible to open the music app from my app in android, or is it best to write a whole new music app inside of mine. I would rather use theirs since the user will already be comfortable with it.

Answer 1

I found one way to do this.

Intent intent = new Intent();  
intent.setAction(android.content.Intent.ACTION_VIEW);  
intent.setDataAndType(Uri.parse(YOUR_SONG_PATH), "audio/*");  
startActivity(intent);
