As per posted in https://developer.android.com/training/app-indexing/deep-linking.html, we could start the deeplink App Launch using the below command
adb shell am start -W -a android.intent.action.VIEW -d "example://gizmos" com.example.android
But if I want to start debugging, I could add a
-D, as below
adb shell am start -W -a android.intent.action.VIEW -d "example://gizmos" com.example.android -D
My App got launched, but it is there stating
Waiting For Debugger
Application Android System (process system:ui) is waiting for the debugger to attach
From there, I check my Android Studio, it is not attached. Wonder how could I get it attached?
You'd either have to manually attach it after launching, or already have the app running and attached then launch your deeplink. There's no way for the phone to know it needs to attach to a debugger on a connected PC when it launches an app.
