I am using this library:

http://grepcode.com/snapshot/repository.grepcode.com/java/ext/com.google.android/android/4.3_r2.1/

I pulled the jar and added it to my project - the project I am trying to build is:

https://github.com/domi007/silentSMS/

I understand it is because my xms and xmx values are too low. I increased them in:

/Applications/Android Studio.app/bin/idea.vmoptions so that it now says:

-Xms256m
-Xmx1024m

however i still get the error. Any idea why this would be caused. Apart from the silentSMS app being an Eclipse project and me porting the code over to Android Studio I have changed nothing. In terms of Android Studio spotting errors - it doesnt, everything else looks fine. Help would be greatly appreciated.
Thanks

Answer

I think there's a separate way to raise the heap limit of the dexing operation. Add this to your android closure in your build.gradle file:

dexOptions {
    javaMaxHeapSize "4g"
}

and see if that helps.
