Java cannot find '/platform-tools/adb' (Building app with react-native)

Question

I run npx react-native run-android and I get this

This seems to be the problem, It's looking for platform tools in ~/ and not in ~/Android/Sdk

java.io.IOException: Cannot run program "/home/u/platform-tools/adb": error=2, No such file or directory `

You can ignore this, stack won't let me post this if I don't add more text, but I think it's already a good explanation
