OutOfMemoryError when compiling my android app with gradle

Question

I'm trying to build my app via gradle and I'm currently having this issue after running a ./gradlew build:

:myApp:compileDebug


The system is out of resources.

Any idea?

Answer 1

I think I fixed it. I got the solution from this post. i.e:

replacing in gradlew:

GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\""

by

GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\" \"-Xmx1024m\" \"-Xms256m\" \"-XX:MaxPermSize=1024m\""
