Asking for permissions in a better way

[aaaaalbert]

SensibilityActivity currently tries to ask for all relevant permissions en bloc, but what happens on my Nexus 6 running Android 7.1.1 is that whenever the app gains focus, it asks for the next permission. Thus, to get everything agreed to, I have to change between apps about ten times.

However, maybe there isn't a better way to do this on Nougat. On previous Android versions, you could blanket-accept all of an app's permissions at install time...

ADB notes too that

Blanket-accept does not work anymore since Android 6.0. You now have to ask for permissions at runtime.
I can't reproduce this 7.1.1. behavior on 6.0, where above referenced function iterates over all the dialogs without requiring to switch between apps.

UPDATE:
I updated this comment because I missed some lines in the log. It makes more sense now.

I traced the permission check/request functions (using debug statements) and here is what happens:

D/SensibilityActivity: Entering onStart
D/SensibilityActivity: Calling checkRequestPermissions
D/SensibilityActivity: Entering checkRequestPermissions
# ... stripped permission check for permissions that have already been granted

D/SensibilityActivity: Checking permission android.permission.READ_PHONE_STATE
D/SensibilityActivity: Requesting permission android.permission.READ_PHONE_STATE
# .... stripped rest of permission requests that behave like  android.permission.READ_PHONE_STATE

# The activity lifecycle continues in `onStart` and then goes into `onResume` ...

# Then the Permission Request AlertDialog pops up on the UI and the log freezes
# I click YES, then the next Permission is requested, I click YES, then the next ... and so on

# Once I have clicked through all AlertDialogs, the log prints all
# debug statements from the `onRequestPermissionsResult` callback at once:

D/SensibilityActivity: Permission was requested by Sensibility
D/SensibilityActivity: Requested 1 permission(s)
D/SensibilityActivity: Received 1 permission request result(s)
D/SensibilityActivity: Permission granted by user
# ... stripped rest of permission request results

This log, SO and actually just the fact that requestPermissions has a callback function suggest that we are dealing with an asynchronous call. That alone is not necessarily a problem nor an answer to this issue.
Maybe the fact that the log only resumes after all AlertDialogs have been dismissed is an interesting insight? Maybe there is a race condition in the AlertDialog queue on 7.1.1?
