It could be a lot of reasaons, I fixed it by:

step 1. go to ur_project/android/gradle.properties add the line

org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

step 2. go to ur_project/android/app/build.gradle, inside android{ .... } add

dexOptions {
   incremental true
   javaMaxHeapSize "4g"
}

Sometimes just delete Build folders and retry. In my case, this problem happen after upgrade the RN version, so cleaning the builds folders, has solved.

npx react-native start &

npx if you have the package not installed yet.
