Answer 1

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.READ_CONTACTS)
    != PackageManager.PERMISSION_GRANTED) {    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CONTACTS)) {        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.    } else {        // No explanation needed, we can request the permission.        ActivityCompat.requestPermissions(thisActivity,
                arrayOf(Manifest.permission.READ_CONTACTS),
                MY_PERMISSIONS_REQUEST_READ_CONTACTS)        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}
