Unity Remote
Unity Remote is a great application created by the Unity team. It allows developers to connect their Android powered devices to the Unity Editor and provide mobile inputs for testing. This is a definite must for any aspiring Unity and Android developer. If you are using a non-Amazon device, acquiring Unity Remote is quite easy. At the time of writing this book, it could be found on Google Play at https://play.google.com/store/apps/details?id=com.unity3d.androidremote. It is free and does nothing but connect to the Unity Editor, so the permissions are negligible.
If, however, you are like the ever-growing Amazon market or seek to target Amazon's line of Android devices, adding Unity Remote becomes a little trickier. First, you need to download the APK. It can be found at: http://files.unity3d.com/ricardo/AndroidRemote.apk. Be sure to download the file to a location that you can easily get the whole file path for. In the next section, we build a simple application and put it on our device. Follow along from the Start Console step, replacing the simple application with the downloaded APK.
