deleteInstanceId() is a blocking call. It cannot be called on the main thread. If you only need to call it for development and testing, you can use a simple Thread:

            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        FirebaseInstanceId.getInstance().deleteInstanceId();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }).start();
