Step 1 :
Don't use react-native run-android.
Step 2 :
If you are using Windows and you don't have the file gradlew.bat (but only gradlew), download it from here or copy it from an another react-native project.
Step 3 :
In directory /android execute the command gradlew tasks or gradlew.bat tasks if you are on Windows.
Check the commands that can be used in Install tasks
Install tasks
-------------
installDevKernelDebug - Installs the DebugDevKernel build.
installDevKernelDebugAndroidTest - Installs the android (on device) tests for the DevKernelDebug build.
installProdKernelDebug - Installs the DebugProdKernel build.
installProdKernelDebugAndroidTest - Installs the android (on device) tests for the ProdKernelDebug build.
uninstallAll - Uninstall all applications.
uninstallDevKernelDebug - Uninstalls the DebugDevKernel build.
uninstallDevKernelDebugAndroidTest - Uninstalls the android (on device) tests for the DevKernelDebug build.
uninstallDevKernelRelease - Uninstalls the ReleaseDevKernel build.
uninstallProdKernelDebug - Uninstalls the DebugProdKernel build.
uninstallProdKernelDebugAndroidTest - Uninstalls the android (on device) tests for the ProdKernelDebug build.
uninstallProdKernelRelease - Uninstalls the ReleaseProdKernel build.
Use the command gradlew installDevKernelDebug.
Step 4 :
If you are using react-native, go in the root directory and run npm start or expo start if you are using expo.
In the browser go to http://localhost:19002 (or the port it says on your console).
Select the local connection and recover the value like
expXXXXXXXXXXXXXXXXXXX://127.0.0.1:19000.
Check the file on .\android\app\src\main\java\host\exp\exponent\generated\DetachBuildConstants.java and copy the value in DEVELOPMENT_URL variable.
Step 5 :
Exit Metro Bundler with CTRL+C on the console.
Step 6 :
Run cd android to enter ./android/ directory
Step 7 :
Run gradlew installDevKernelDebug or other task you listed on Step 3.

Answer 2

You might be missing the Android NDK, can try to install it using the SDK Manager of Android-Studio.
