Lampe2
Project to control your raspberry-pi-zero-w unicornhathd lamp with your android phone. This is the Android part.
Current minSdkVersion 14, so it should work for Android 4.0 upwards, though I only tested it on Android 7.1
Project compiles with Android Studio 3.3.2. Might work with other versions too, but that is the one I used.
Installation
See this instructable for details.
Base
I used this tutorial for the bluetooth communication.
Note:
You should follow the instructions on the raspberry part first.
If you did, you are now paired with the raspberry.
Use Android studio to install the app and have fun :)
