This issue will occur on Android 6.0 Permission Error , So check for Requesting Permissions at Run Time https://developer.android.com/training/permissions/requesting.html — Android Surya, Jul 20 '16 at 10:30

This is because you have to ask permissions to user in android version 6.0 for android.permission.READ_PHONE_STATE

int permission = ContextCompat.checkSelfPermission(thisActivity,
    Manifest.permission.READ_PHONE_STATE);
if(permission != PackageManager.PERMISSION_GRANTED) {
    // ask permission here
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.READ_PHONE_STATE}, 101);
} else {
    // do your work here
}

the above code should be in onCreate method of activity.

and check if user has granted the permission in onRequestPermissionsResult method of activity

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    if (requestCode == 101) {
        if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            // permission was granted, yay! Do the
            // IMEI Getting task here

        } else {
             // permission denied,
             //  don't do the functionality that depends on this permission.
        }
    }
}

Hope this'll help.
