If you've been getting the following error message: Could not read path 'C:...\justice_hub\android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-af'.
Then the error can be fixed with a couple lines in the terminal. Github issue report found here.
Execute the following commands Make sure that you're in the justice_hub root directory
cd android && gradlew cl
If this doesn't work look into adding gradlew to your path so that it works in the command line This will clean the gradle build of your android app, and will fix the missing file error message
cd .. && react-native run-android
All this does is navigate back to the root directory and then run your app.
This is all that it took for me to be able to successfully build the app after running into that error.
