MapFragment Google Maps API v2 Memory Error / Memory Leak

Over the past few days I have read several similar publications, but none of them specifically answered this problem. I'm starting to get the OOM problem after ~ 2 minutes of aggressive panning of the map and zooming with the hybrid map. The application also seems to hold memory after a failure, because it takes less time to reach OOM after the first failure. I reduced the code only to Activity using MapFragment and still got the same OOM. I used DDMS and MAT to try to isolate the problem, besides adding android:largeHeap="true" , which only delays OOM. Reorienting the screen is not a problem because I set android:screenOrientation="portrait" in my manifest. Any help would be appreciated.

Update 2014-08-25: Is this supposed to be fixed back in May 2013?

Update 2014-09-06: Still not successful, the only good option is to use Normal instead of Hybrid . It seems that the GC may keep up with the images.

try calling the onPause, onResume, onLowMemory map in the corresponding fragment methods.

I ran into this problem while trying to run the application in demo mode for several hours at a time. No matter what I tried, after 30 minutes I will see this crash without a stack report.

I tried many different things, but that was the only thing that worked for me. This is not an error for a map error, but it does not allow my application to crash:

  <application ... android:largeHeap="true">
