So I have been having some problems with launching the initial react-native template project on android. And after consulting someone I was told that jdk 17 is not supported. But I really don't want to downgrade as this could break other things that I already have and work with. To be specific this is the error I get:

> Task :app:processDebugMainManifest FAILED 11 actionable tasks: 2 executed, 9 up-to-date FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:processDebugMainManifest'. > Unable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed module @7ec6bc9b * Try: Run with --stacktrace option to get the stack trace.

I have looked at this already and nothing worked. Gradle: Execution failed for task ':processDebugManifest'

So I solved this issue by installing JDK 16 on my system and everything is solved and running fine. I don't know if the problem was with Gradle or JDK or react-native but hope that in the future jdk 17 is supported.

If you have the same issue then you can go to: jdk 16

1)Download and Install the JDK 16.

2)Add the path to your jdk in the PATH in your system environment variable.

3)Open cmd and do java -version you should see something like

java version "16.0.2" 2021-07-20 Java(TM) SE Runtime Environment (build 16.0.2+7-67) Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing)

To know if this is a java version-related issue, You need to check your Gradle version.

currently only Gradle version 7.3 support java 17.

You can check gradle compatibility matrix to check.

you can check your version with the command line by typing gradlew.bat -version

If your Gradle is version 7.3 then it has nothing to do with the JDK version.

I do have Gradle version 7.3.3 installed and working correctly.
It seems that Gradle is throwing this error bcz I can't build my project.

For me react native didnt work successfully with OpenJdk 17. Was getting error building apk

For me the problem got fixed with installing OpenJdk 11.
