Building a module for Android is trivial (if you've done it before for Linux).
>From the directory from which your module source is: # CROSS_COMPILE=arm-eabi- ARCH=arm make -C /android/kernel/directory M= $PWD modules Note that the CROSS_COMPILE will only work as above if your Android toolchain is in your system path. As for interfacing at the application level as a sensor, well, I have not done that yet, but it seems like a cool idea. Like yenchengwang mentioned, I would take a look at sensor_qemu.c to get an idea of how it was done. I would imagine that some knowledge in JNI will be required, though. Let me know how it goes!
