Here is my first step in the Android world...
The app sends yaw/pitch angles as UDP packets to a remote computer that controls two servos (via a Pololu Maestro module).
In fact the remote computer runs the exact same code I used for my Raspberry-Pi-WiFi-Quadcopter. Indeed, the packets I send also contain throttle, rudder, elevators and ailerons controls (all set to 0 here). So in theory, I could just add 4 sliders to the app and it could fly the quadcopter :) but that wouldn't be very practical or safe!. It'd be better to use virtual joysticks (touchscreen-based), or maybe sensors like the gyro.
There are still a few things I need to improve in the code (like a loop that sends the packets regularly instead of in response to UI events only), but this is already a good starting point...

GoPro Hero 3 Black Edition battery life
In this test, the GoPro is recording a video for as long as possible (the camera shuts itself down when there's no battery left). Here are the results:
A bit disappointing. You better have spare batteries!
Video settings | Wifi | Time |
---|---|---|
1920x1080 50fps | Off | 1h20 |
1920x1080 50fps | On | 55min |
1920x1080 24fps | Off | 1h38 |
1920x1080 50fps | On | 1h19 |
