This is just a very simple demo which implement this virtual joystick android Library.

Code

For those who don't want to browse the project or files, here it is...

Gradle file

Add library to dependencies.

dependencies {
    ...
    compile 'io.github.controlwear:virtualjoystick:1.3.0'
}

Manifest

Force activity to landscape.

<activity
    android:name=".MainActivity"
    android:screenOrientation="landscape">
    ...

Layout

Just a couple of TextView and JoystickView to activity_main.xml

                JoystickView joystickLeft = (JoystickView) findViewById(R.id.joystickView_left);
                JoystickView joystickRight = (JoystickView) findViewById(R.id.joystickView_right);
                joystickLeft.setOnMoveListener(new JoystickView.OnMoveListener() {
                    @Override

                            UdpClientThread.sendMessage("LA:" + String.format("%03d", angle) +
                                    " LS:" + String.format("%03d", strength) + " ;", IP[0]);

                        }
                    }

                joystickRight.setOnMoveListener(new JoystickView.OnMoveListener() {

                });
            }
        });
    }
}

And that's it.
