Memory issue when run Android integration test

I met memory problem when running android ui test on circleCI. It is fine if just running unit test, but failed if runnning instrumentation test. I think the reason is my project using multi dex, but I have no way to limit the memory of executing test. Could someone help me solve the problem?

Here is part of memory-usage.txt:
