Android Permission Result wrong value

In Qt ( http://doc.qt.io/qt-5/qtandroid.html#PermissionResult-enum ):

enum QtAndroid::PermissionResult {
Granted = 0,
Denied =  1
}

Meanwhile:
https://developer.android.com/reference/android/content/pm/PackageManager#PERMISSION_DENIED

public static final int PERMISSION_DENIED = -1;

While it's best practice to use enums, using the platform value is also best practice.
In this way, the only portable code can only ever == Granted or != Granted, and checking for equivalency of Denied is not the same thing as checking for Permission.PERMISSION_DENIED - it is now a thing that will never work.

You can use

enum QtAndroid::PermissionResult {
  Denied =  -1,
  Granted = 0
}

Now there is code that translates 1>1 and any apps that are sharing these results between Qt and Android SDK have to implement that too.
