React-native problem - Execution failed for task ':app:compileDebugJavaWithJavac'

Question

So I'm working with my team on project. At first I had 2 problems which you can find on this page:

React-native problem with launching the app

I don't know if those 2 problems are gone or I just put another one on top of them but here it is. If you have any clue please write me, I'm trying to fix this problem for so long. At first when I merged my branches with other teammates everything was fine, but then this occure after second merge:

Answer 1

Have you install android-platform-tools?

If it's already, check if your device is connected with run this:

$ adb devices

It will show your Device ID

If your device connected, but the error still appear, try this:

$ adb -s reverse tcp:8081 tcp:8081

Then run again. If still error, try this:

$ npx react-native run-android --deviceId

Answer 2

I think you made some mistakes while upgrading version or installing new package.

Please check this.
