This plugin sets the maximum memory usage for Gradle when building Android apps.
From Monaca Cloud IDE menu, go to Configure → Cordova Plugin Settings .
Under Available Plugins section, hover over the the
MaxMemForAndroidBuild plugin and click Enable button.
If you want to set the memory size used in the Android build process to 4096Mb, you can do so as follows
<preference name="monaca:jvmargs" value="-Xmx4096m"/>
Then you also need to change the maximum memory size used by Gradle Daemon, for example, if you want to set it to 4G, set it as follows
<preference name="monaca:env:GRADLE_OPTS" value="-Dorg.gradle.jvmargs='-Xmx4G'"/>
