Enabling Developer Options on Android
To allow for development on the Android device, the Developer Options have to be enabled. To do so, navigate to the Build number. On the Samsung Galaxy s7, the build number is found in Settings > Software info > Build number . Now tap on this number seven times to unlock the developer options. A toast notification should pop-up that looks like Figure 4.
We can now navigate towards Settings > Developer options and enable USB debugging. Connecting the device to a PC will now show a pop-up asking us to allow USB debugging, it is a good idea to always allow this from the development PC as shown in Figure 5.
