I install react-native on windows 10 from this official site(official doc)

And if I put command react-native run-android

I got error like this below

:app:compileDebugJavaWithJavac

:app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.). :app:compileDebugJavaWithJavac FAILED

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

    Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_101 contains a valid JDK installation.

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

I found answer - need indJAVA_HOME variable, as this image - a busy cat
(source: joxi.ru)

This version java must be valid and must contain tools.jar file. In my computer i have 2 versions, default version haven't tools.jar file.
