如何完成应用程序并返回上一屏幕

Question

I'm launching my app via implicit intent from other application, and after I do some work I want to exit the app and go back to where I was.

My code:

  if (intent.type == MY_INTENT_TYPE) {
            CoroutineScope(Dispatchers.IO).launch {
                delay(5000)
                progressBar.visibility = View.GONE
                withContext(Dispatchers.Main) {
                    finish()
                }
            }
        }

The problem I that I'm getting those errors when I call finish()

How can I exit from the app and get back to the previous screen without errors?

Well..my mistake.

The code is totally fine, I just forgot to move

  progressBar.visibility = View.GONE

To the main thread
