Out of memory error: Java heap memory on Android Studio

Question

How do I fix java.lang.OutOfMemoryError: Java heap space when compiling my Android project?

I get this after I upgraded to version 1 of Android Studio.

Answer 1

Just add this to the gradle file:

android{
testOptions {
        ....
        unitTests.all {
            jvmArgs "-Xmx2g" // to avoid outOfMemory exception
        }
        ....
    }
}
