问题 I have 2 Activities, each in seperate applications. Activity1 has a button the user can click and it calls the second activity using an intent in its onClick() method: Intent myIntent = getPackageManager().getLaunchIntentForPackage(com.myProject.Activity2); startActivityForResult(myIntent, 600); This correctly launches Activity2 from Activity1, but onActivityResult gets called in Activity1 before onCreate gets called in Activity2, instead of in onBackPressed() where I set up the return intent
