Hi,
I don't know if is a problem, but when I run on device the B4A bridge and, after I have connected from IDE , I compile & run my application, it seems not connected, infact I have the following message: No device found. Please start an emulator by choosing ... etc. etc.
Apologies if this is obvious but when you run the bridge app on your Android device have you pressed the bridge apps start button and checked your device and the computer are both connected to the same wi fi network?
Once you have done those things and connect to bridge in the B4A ide all you should need to do is type in the ip address that B4A gave you.
