PermissionsAndroid
PermissionsAndroid provides access to Android M's new permissions model. The so-called "normal" permissions are granted by default when the application is installed as long as they appear in AndroidManifest.xml. However, "dangerous" permissions require a dialog prompt. You should use this module for those permissions.
On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest, so check should always result to true and request should always resolve to PermissionsAndroid.RESULTS.GRANTED.
If a user has previously turned off a permission that you prompt for, the OS will advise your app to show a rationale for needing the permission. The optional rationale argument will show a dialog prompt only if necessary - otherwise the normal permission prompt will appear.
