BLUNO Problems

I got my BLUNO with the accessory shield (DFR0270) yesterday. And I have upgraded the firmware to version 1.6

But can't get any of the bluetooth features to work! :( :( :(

1) When ever I try to install the APK file - android reports that the file is corrupt.

2) When I scan for bluetooth devices, the BLUNO shows up as DFBLEduinoV1.0 - but do not have the PIN to connect to it :(

Am using Arduino IDE version 1.0.5
