We had a library project that we shared between the tablet and the phone app. The only problem we faced was that eclipse didn't always update the lib correctly and we had to clean the projects every time we added a new public function/class to the library.

Apart from that it worked out great. Writing a simple Activity for the phone took less than 5 minutes and we could work on the OpenGl part without the tablet. But it all depends on the application that you are trying to build.

Also I hear you can run a x86 version of android inside virtual box, which is way faster than the emulator, check it out.

They even failed to mention this little bit of information before we started working.

You will see the app once we get the tablets :)

We used two kinds of filters for the sensor data - a simple alpha filter and rolling averages. Both of them can be adjusted by the slider on the left.
