Learning Android - Audio Volume Control

I've been spending some time learning to program using Android.  It's been on my list for a long time and I'm going slow and building fun little things for my 2 year old. Nothing commercial, just something for him to enjoy.

The first app I built had an issue that the audio controls on the device wouldn't work unless a sound was actually playing.  Found a really simple work around.

Add this call to the onCreate method in the activity.

        setVolumeControlStream(AudioManager.STREAM_MUSIC);

Pretty simple little fix.
