Robolectric java heap size error

Question

So I am running my tests using Robolectric 3.1.4. In another project I had no problems running all my test with robolectric, but right now I always get this error:

java.lang.OutOfMemoryError: Java heap space

When I remove some views of the activity, the problem stops...

Well, my question is: How can I increase the heap size in the project or how can I make robolectric consume less memory?

Any help is appreciated!

Answer 1

This kind of problem usually happens when you're displaying too many images on your activities. Probably using some ViewPager? If that's the case, you can read this , which explains how to use cache to store images and reduce memory consumption.

Another solution is increasing the heap size, by setting this on the AndroidManifest.xml: android:largeHeap=”true” .. But keep in mind that this is used mostly on apps that require a lot of memory like games, video processors, etc
