Tip of the Day: largeHeap=”true”

If your app is done in API 11 or higher, in the < application /> in the Android Manifest.xml, you can use largeHeap=”true” which will allow the application to use more heap if it is available.

Bigger heap though isn’t necessary good because now your app will spend more time during garbage collection. Users will complain that their other apps are being kicked out of memory.

Heap Size limits
– G1: 16MB
– Droid: 24MB
– Nexus One: 32MB
– Xoom: 48MB
