Can't receive data

[ianchung]

Hi there,
I used Android-USB-Serial-Monitor-Lite.apk to connect with arduino UNO and succeed to send and receive data from UNO. When I import Android-USB-Serial-Monitor-Lite and PhysicaloidLibrary source code to create a new apk, then only succeed to send data, but receive nothing(the UNO upload code is when UNO receive "d", the 13 pin LED will light and return "hello".).

Is there any possible problem? In eclipse only show 8 warning (dead code), but it still can build an apk file.
