Android Question MySocket.Connect Crash

You need to check the logs (requires USB debug mode as it is in release mode) and post the error message.

There in lies the problem. I am using the USB port of the phone to attach to a serial device. So USB debug isn't possible. I'll see if I can do this through Bluetooth, thus freeing up the port.

You could try catching the exception in the Starter Service and writing the exception to a text file on the device.

You should use AsyncStreams to read from the stream or: https://www.b4x.com/android/forum/threads/44760/#content
