I've read a number of similar posts over the past few days, but none that specifically answer this problem. I start getting an OOM issue after ~2 minutes of aggressive map panning and zooming with the Hybrid map. The app also seems to hold onto the memory after the crash because it takes less time to reach OOM after the first failure. I scaled down the code to just an Activity with a MapFragment and still get the same OOM. I've used DDMS and MAT to try and isolate the problem, in addition to adding android:largeHeap="true" which only delays the OOM. Screen re-orientation is not an issue because I'm setting android:screenOrientation="portrait" in my Manifest. Any help would be appreciated.
Update 2014-08-25: This is supposed to be fixed back in May 2013?
Update 2014-09-06: Still no success, the only good option is to use Normal instead of Hybrid. GC seems to be able to keep up without the imagery.

try call map onPause, onResume, onLowMemory in corresponding Fragment methods.
I ran into this problem trying to run an app on demo mode for a few hours at a time. No matter what I tried, after 30 minutes, I would see this crash without a readable stack report.
I tried many different things but this was the only thing that worked for me. It's not a fix for the map bug, but it kept my app from crashing:
<application
...
android:largeHeap="true">
