How can I prevent a re-start of my app when the phone is rotated?

Question

In my app I don't want to restart a media player once it starts if the user rotates the phone. How can I prevent a re-start of my app when it is rotated because it stops the running sound file that is playing?

Please show me the code I need to add and where to add it.

Thanks.

Truly, Emad

You have to redesign your application to play the music from a service instead of from your main activity. Your main activity can at any time be killed by the operating system if it decides it needs memory.

I'd just like to point out that a Service is not immune to being killed than an Activity is. I think your suggestion to use a Service is still valid, however. Since it will be a user-visible Service, see http://stackoverflow.com/questions/3856767/android-keeping-a-background-service-alive-preventing-process-death – Jon Willis Sep 11 '11 at 17:39
It is however less likely which is what you most likely want. But agreed a bit clumsily formulated. – richardwiden Sep 11 '11 at 17:43
Hi Richard, I'm going to see what makes this code at http://www.java2s.com/Code/Android/Media/UsingServicetoplaymediafile.htm works since it uses a service to play a media file. If I can fiture it out I will apply it into my app. Thanks everyone for the fast replies. – Emad-ud-deen Sep 11 '11 at 18:45
Hi Richard, I tried the code but it had parts missing but did find a better one at http://marakana.com/forums/android/examples/60.html and it had everything I needed to get a working demo of the media file to play even when I moved the phone around from portrait to landscape. I will now get that into my app. Truly, Emad – Emad-ud-deen Sep 11 '11 at 19:59
