Listview Does Not Work On Fragment - Outofmemoryerror: Failed To Allocate

ListView does not work on fragments, I tried some codes on this, but again it continues to say - 'the app is stopped' My Main Activity public class OrtaMain extends Fragment {

Solution 1:

Here's what I recommend, it should help...

You can ignore the problem not recommended and increase the heapSize by adding this to your android manifest file:

<application android:largeHeap="true"

Also set Bitmap.Config type RGB_565 instead of ARGB_8888 to keep the bitmaps smaller.

But the best option here would be to take some time and profile your application with LeakCanary and take a look at this video to learn Memory Management for Android - Google I/O 2011: Memory management for Android Apps (Play from 4:12 to see why largeHeap=true is bad.) then at 8:31 they go into detail on understanding heap usage.

The large heap fix it's a temporary fix and shouldn't be considered final. I highly recommend profiling, Take a look at the Fragment life cycle the method that is called before the Fragment is completely done with is the onDetach() method, you may want to release all the resources here. The fact that a fragment itself is destroyed and gc'ed does not mean all resources you allocated were removed.
