Android: Add function to check permissions at run-time.

Browse Source 
This is convenient when we you want to check which permissions the
application has been granted at run-time. On Android device running
Android 6.0 or newer the permissions might be changed by the user,
so there are cases where this will be needed to determine what
APIs are available. On older devices or if the application is built
for an older SDK version, the old behavior is used, that is, the
permissions from the manifest is the permissions the application has.
