Android Code Snippet Memory Usage

Of my 235+ users I have one (using a Samsung S6) that is generating out of memory very often.

This code hasn't helped - I never seem to use more than what is shown yet their device seems to get the out of memory

Maybe this will help someone else



So saw this article: https://stackoverflow.com/questions/3571203/what-are-runtime-getruntime-totalmemory-and-freememory

Bottom of article

512 MB What device is it?

 

[Robert Valentino]

My Samsung S5, S6 or 10" Tab A all report the 512mb

I believe 512 MB is what you get when you use LargeHeap

SetApplicationAttribute(android:largeHeap,"true")
