Create a new project in Android Studio, entering PermissionDemo into the Application name field and com.ebookfrenzy as the Company Domain setting before clicking on the Next button.

On the form factors screen, enable the Phone and Tablet option and set the minimum SDK setting to API 19: Android 4.4 (KitKat). Continue to proceed through the screens, requesting the creation of an empty activity named PermissionDemoActivity with a corresponding layout named activity_permission_demo.

Run the app on a device or emulator running a version of Android that predates Android 6.0 and check the log cat output within Android Studio. After the app has launched, the output should include the “Permission to record denied” message.

Next, implement the onRequestPermissionsResult() method so that it reads as follows:

}

</pre>

The method still checks whether or not the permission has been granted, but now also identifies whether a rationale needs to be displayed. If the user has previously denied the request, a dialog is displayed containing an explanation and an OK button on which a listener is configured to call the makeRequest() method when the button is tapped. In the event that the permission request has not previously been made, the code moves directly to seeking permission.
