If you want to upload your precompiled Arduino sketches to your boards via Bluetooth from your Android device then this is what you are looking for. This is the test version, the full version is available here: https://play.google.com/store/apps/details?id=com.infomultiverse.avrflasher

Quickstart guide is found here: http://avrf.infomultiverse.com .

It works with almost any Bluetooth module. Included is a serial terminal monitor which works via bluetooth to see program output as printed with Serial.print() etc.
This app does not compile your scetches to hex files for flashing. You can use ArduinoDroid to compile your sketches.
