Android: (Memory Management) How to interpret D/dalvikvm log

D/dalvikvm log is shown in the Log whenever GC happens.

Reason for GC
D/dalvikvm( 9050): GC_CONCURRENT freed 2049k, 65% free 3571K/ 9991K, external 4703K/5261K, paused 2ms+2ms

Reason for GC:
- GC_CONCURRENT : heap has been mostly filled up, so GC runs before heap is full.
- GC_FOR_MALLOC : heap is entirely filled up, we had to STOP and GC.
- GC_EXTERNAL_ALLOC : (Won't see this in Honeycomb+) Bitmap are externally allocated momory.
- GC_HPROF_DUMP_HEAP
- GC_EXPLICIT : called when you call 'System.gc()';
