GC overhead limit exceeded when enable R8 Shrinker in Android Studio

I'm using Android Studio 3.4 (Canary 9), when I build my app, it failed with the following error

Task :app:transformClassesAndResourcesWithR8ForDebug

R8 is an experimental feature. If you experience any issues, please file a bug at https://issuetracker.google.com, using 'Shrinker (R8)' as component name. You can disable R8 by updating gradle.properties with 'android.enableR8=false'.

AGPBI: {"kind":"warning","text":"Missing class: java.lang.instrument.ClassFileTransformer","sources":[{}],"tool":"D8"}

Task :app:transformClassesAndResourcesWithR8ForDebug FAILED

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ':app:transformClassesAndResourcesWithR8ForDebug'.

GC overhead limit exceeded

When I disable R8 by putting android.enableR8=false into gradle.properties. Everything is working fine.

So how can I fix this error without disable R8 Shrinker? Because I'm really want to test functionality of R8.

Sometimes adding JVM heap memory does not solve the problem especially on systems that have limited memory, it will cause other problems. my recommendation is to try replacing the Garbage Collector.

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+UseConcMarkSweepGC

GC overhead limit exceeded is an exception throw by default java 8 garbage collector (Parallel). In my case, it solved the problems.

As you said you are not using any custom JVM args, try it out.

In your gradle.properties file try several values for memory settings. For example try to set

org.gradle.jvmargs=-Xmx4096m

As suggested by the commented section:

Specifies the JVM arguments used for the daemon process.

The setting is particularly useful for tweaking memory settings.

org.gradle.jvmargs=-Xmx1536m

I've used R8 in my project and all worked fine.
