Out of memory error while running gradlew assembleRelease - react-native

Question

I am getting this error while making a release build for my react native project:

Expiring Daemon because JVM heap space is exhausted      > Task :app:transformDexArchiveWithDexMergerForRelease FAILED  FAILURE: Build failed with an exception.  * What went wrong: Execution failed for task ':app:transformDexArchiveWithDexMergerForRelease'. > java.lang.OutOfMemoryError (no error message) 

Done some research and made some changes, which are below:

1. Added android:largeHeap="true" to the application tag in the AndroidManifest.xml

2. Added

   dexOptions {     javaMaxHeapSize "4g"  } 

   in the android/app/build.gradle file.

3. Added the below code to gradle.properties

   org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=4096m -XX:+HeapDumpOnOutOfMemoryError org.gradle.daemon=true org.gradle.parallel=true org.gradle.configureondemand=true 

Still I am not able to get rid of this error. Any permanent way to get rid of this error and how is it caused??

Answer 1

configuring gradle.properties:

org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=4096m -XX:+HeapDumpOnOutOfMemoryError org.gradle.daemon=true org.gradle.parallel=true org.gradle.configureondemand=true
