Answer 1

Your SDK path is not correct you need to add a correct path in the below file: sa project > android > local.properties

Add the path like below example:

sdk.dir = /Users/admin/Library/Android/sdk

After added use the following commands:

1. cd android/
2. ./gradlew clean
3. cd ..
4. Command: react-native bundle --platform android --dev false --entry-file indexcsasa.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
csacs
5. react-native run-android

Answer 2

Sometimes the build fails, but it still runs .Have you tried connecting your app via the WIFI to the remote server? Check the connect via wifi method React connect via Wifi

I guess that will work
