Android logs 'GC_EXTERNAL_ALLOC' 'GC_FOR_MALLOC'

Question

While running my apps, I have got this kind of logs:

GC_EXTERNAL_ALLOC freed 2K, 38% free 8772K/14087K, external 17480K/17998K, paused 87ms
GC_

Answer 1

I was also looking for this information.

GC stands for garbage-collector, which collects unused objects during runtime of your app.

1. • GC_EXTERNAL_ALLOC: Means that the VM is trying to reduce the amount of memory used collectable objects, to make room for non-collectable objects.
   • GC_FOR_MALLOC: Means that the GC was triggered because there wasn't enough memory left on the heap to perform an allocation. Might be triggered when new objects are being created.
   • GC_CONCURRENT: Triggered when the heap has reached a certain amount of objects to collect.
2. I am guessing that the 38% free means that 38% of the heap is unused. 8772K would be the size of the used memory on the heap and 14087K would be the size of the heap.
3. I don´t know, sorry.

Please note that all of this information is based on a post from Robert on a similiar question posted here on stackoverflow. All credit (as long as this is correct) goes to Robert.
