Android will ignore permission request and will not show the request dialog if the user's action implies "don't ask again." This leaves the app in a crippled state and the user confused. Google says "don't try to convince the user", so it returns false for `shouldShowRequestPermissionRationale`. To help the user proceed, we show the `Request permission` button only if `shouldShowRequestPermissionRationale == true` because there's a good chance the premission request dialog will not be ignored. If `shouldShowRequestPermissionRationale == false` we instead show the "rationale" message and a button to open the app info dialog where the user can explicitly grand the permission.

Permission request
Since Android 6.0 (API level 23):
Android will ignore permission request and will not show the request dialog
if the user's action implies "don't ask again."
This leaves the app in a crippled state and the user confused.
Google says "don't try to convince the user", so it returns false for shouldShowRequestPermissionRationale
.
To help the user proceed, we show the Request permission
button only if shouldShowRequestPermissionRationale == true
because there's a good chance the permission request dialog will not be ignored.
If shouldShowRequestPermissionRationale == false
we instead show the "rationale" message and a button to open
the app info dialog where the user can explicitly grand the permission.
