Runtime Permission in Pre-Marshmallow

As we have already discussed about Requesting Runtime Permission in Marshmallow, now what if we want to give suuport for Runtime Permission in Pre-Marshmallow devices.

And the solution is : Support Library

If we want to use checkSelfPermission() we need to use minSdkVersion 23 but what if we want to give support in both Marshmallow and pre-marshmallow devices. There are small changes we need to do with those methods we are using for Marshmallow.

– ContextCompat.checkSelfPermission()

No matter application is run on Marshmallow or not. This function will correctly return PERMISSION_GRANTED if the permission is granted. Otherwise PERMISSION_DENIED will be returned.

– ActivityCompat.requestPermissions()

If this function is called on pre-Marshmallow, OnRequestPermissionsResultCallback will be suddenly called with correct PERMISSION_GRANTED or PERMISSION_DENIED result.

-ActivityCompat.shouldShowRequestPermissionRationale() 

it will always return false, if called on pre-marshmallow.

Here i am sharing demo code, please take a look at that.
