It's many years since, when beta testing B4A with Erel, that I have had to use adb. Ever since B4A-Bridge came available I have used that as I am still mentally scarred from the early days of USB drivers for Android devices.
Now I am playing with a Wear OS watch and was pleasantly surprised when, against my expectation, after compiling a test app B4A magically installed it to the watch! I had expected to need to do a manual adb install. However on another occasion it didn't work so having seen that happen I am puzzled as to the requirements to make it work every time. Enlightenment is requested.
The setup is that my watch is connected to WiFi and I can connect it to adb with a command prompt and do manual installs. There is no indication in B4A that adb is available or that a device is available. What do I need to to ensure that B4A can install to the device any time I want?
