Simulate Out of Memory in android

This is the case when I want to simulate an Out of memory crash in my application. I have a lot of crashes from Crashlytics which indicate that end users are running into OOM crashes and I have not been able to reproduce them with my device (Samsung S4). I just have crashes and no other traces from crashlytics.

I was wondering if someone has a way to reproduce them for their testing (without any code change preferred).

I saw this : Testing Android for Out of Memory scenarios , but haven't got a chance to run it yet.

Any help would be appreciated.

There are a variety of ways to cause OOM.

  1. Use a very large image (incidentally, this use-case is a source of many real OOM issues in apps). I replaced the image for 1 element in my Recycler, so when I scroll to it, it will load the large image (then I can drive the test that way).

  2. Create a loop, that allocates objects to memory. You can just "new" up a bunch of objects in a loop, and run it that way. If you allocate enough Strings, or int objects into a single array, this will run OOM eventually (this is also a good way to gradually build to an OOM condition). Strings will cause OOM faster then ints (but add enough objects to an array, and eventually it will become too large).

I was able to simulate the OOM error by replacing a list of images in the app very large images. 5mb instead of usual 250k. Wikimedia has lot large images you can use. https://commons.wikimedia.org/wiki/File:Snake_River_(5mb).jpg

I hope I'm understanding the question correctly: There's a very easy way if you don't want to change a lot of settings. Go into dev options and make it "no background processeses". Now you can exit out of the app, launch a new one and go back into your original and it'll be wiped out from out of memory
