Dear Kurul,
in MOE 1.1.0 the heap size for the dx process is not large enough in some cases. You can make it larger by replacing the defaultMx value to e.g. -Xmx2048M in the ${user.home}/.moe/moe-sdk-1.1.0/tools/dx script.
Starting with MOE 1.2.0, we will make this configurable from build.gradle.
Best Regards,
Gergely
