instant run java.lang.OutOfMemoryError: GC overhead limit exceeded

Question

I have upgraded to Android Studio 2.1 and I got this error while I am trying to build & run my corporate big project:

Execution failed for task \

Answer 1

Add this to your gradle.properties file.

# The Gradle daemon aims to improve the startup and execution time of Gradle.
# When set to true the Gradle daemon is to run the build.
org.gradle.daemon=true

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
org.gradle.parallel=true

# Enables new incubating mode that makes Gradle selective when configuring projects.
# Only relevant projects are configured which results in faster builds for large multi-projects.
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
org.gradle.configureondemand=true

And on my build.gradle :

....
     dexOptions
         {
               incremental false
               javaMaxHeapSize "2048M" 
               preDexLibraries = false
         }//end dexOptions

....

Answer 2

Another method to set the heap size for particular jobs is to use environment variables for each job. This ensures that the memory is available when the job that requires a higher memory is not in use.

GRADLE_OPTS="-Dorg.gradle.jvmargs=-Xms1024M -Xmx8192M -XX:PermSize=512M -XX:MaxPermSize=2048 -XX:+CMSClassUnloadingEnabled -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8"

JAVA_OPTS="-XX:MaxPermSize=2048M"

Step1: Change build.grade

defaultConfig {
        ...
        // Enabling multidex support.
        multiDexEnabled true
       }

dependencies {
        ...
        compile 'com.android.support:multidex:1.0.0'
    }

Step2: Setting on the Application class

public class MyApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();
    MultiDex.install(this);
}

}

Step3: Change grade.properties

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

It will work!. Thanks.

Answer 4

defaultConfig {
    multiDexEnabled =true
}

add this to your build.gradle file of the app
