Trying to use felUsbSerial library for FTDI USB to serial device to connect to my Android phone, I tried to use the code snip for the project. But I got "unknown type: UsbManager" error. Could anyone show me an example of a working project with right manifest file. Many thanks.
A little update: I added USB library to the project. The "unknown type: UsbManager" error goes away. The project running shows a "Connect" button. Logs says "No connected USB devices". But I connect a FT232RL adapter to the phone USB port. Any suggestion?
