I recently installed React Native on my Windows PC and I created a project but when i try with react-native run-android for android emulator it shows me:

C:\ReactNative\testproj>react-native run-android
info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag.
Jetifier found 855 file(s) to forward-jetify. Using 4 workers...
info JS server already running.
info Installing the app...

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

error Failed to install the app. Make sure you have the Android development environment set up: https://facebook.github.io/react-native/docs/getting-started.html#android-development-environment. Run CLI with --verbose flag for more details.

Your JAVA_HOME is set incorrectly, go through the setup again, everything should works... — Wilson Sim

Sir how do you mean "go through the setup again"? I browse my JAVA_HOME path in env like this C:\Program Files (x86)\Java\jre1.8.0_221, is it correct? — Milos
