startActivityForResult + ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS

Issue

Firstly: I was looking for an answer but didn't found it here neither in Google.

When I run this code (in kotlin and on Android 10):

startActivityForResult(Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS),Uri.parse("package:" + packageName)), 55)

It ends with exception:

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS dat=package:dantem.im }

But this code works without any problems:

startActivityForResult(Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + packageName)), 200)

This code works too, but it show list of all packages which I don't want:

startActivity(Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS))

Where is problem?

Solution

The documentation for ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS says that it takes no input. That is why you will find that many, if not all, Android devices give you the ActivityNotFoundException — your Uri on the Intent causes that Intent to not match any <intent-filter>.
