React-native 0.60 - Android build release failed - OutOfMemory

Question

After upgrading to RN 0.60 - try to run the command:

react-native run-android --variant=release 

Failed with error:

Execution failed for task ':app:packageRelease'. 2 exceptions were raised by workers: java.io.UncheckedIOException: java.io.IOException: Execution of compression failed. java.lang.OutOfMemoryError

The solution for me was:

1. Adding dexoptions in app build.gradle

android {     dexOptions {         javaMaxHeapSize "4g"     }  } 

2. Increasing JVM heap size in gradle.properties

org.gradle.jvmargs=-Xmx4608M 

Answer 1

This solution worked for me.

1. Adding following in android/app/build.gradle:

android {     ...     dexOptions { javaMaxHeapSize "2g" }     ...     } 

2. Adding following in android/gradle.properties:

org.gradle.jvmargs=-Xmx4608M

Answer 2

The way I solved this issue was

1. In your ~android/app/build.gradle file add the following line

 android {      ...      dexOptions {         javaMaxHeapSize "4g"      }      ...      } 

2. In your ~android/gradle.properties add the following line

org.gradle.jvmargs=-Xmx4608m
