Android: Keep MediaPlayer running during Activity screen orientation update

Question

I use a MediaPlayer to play an MP3. Currently I disabled screen orientation changes by using

android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation"

in the manifest. I do want to support landscape mode now - i.e. removed those tags - but have the problem that during the destroy/create cycle the player gets stopped and then restarted. This is okay and I actually do this even manually in onPause() to stop the player when the activity goes in the background.

To keep it running during orientation changes now, I tried making it static (and using the Application Context to create it once). Of course, when I remove the player.stop() in onPause() now, it does what I want - well, until the Activity goes in the background.

So, two questions:

• How can I determine if the Activity will be recreated directly after the call to onStop()
• Or: How can I keep the MediaPlayer running during that cycle, yet stop it when the App goes in the background?

Answer 1

Have you looked at using the onConfigurationChanged() callback to handle some of this logic?

Answer 2

Regarding your question how you can reliably determine whether your Activity is destroyed due to a configuration change, see my answer here: How to save/restore(update) ref to the dialog during screen rotation?(I need ref in onCreate method of activity.)

With this, the answer to your second question should be easy.

Answer 3

Try running MediaPlayer in different Thread.

You can add to this thread a more complex API to which you can call from onCreate/onStop/on*
