Typically to know whether the device is moving or not, you could use the SensorEventListener and catch the onSensorChanged event and write a logic on the x,y and z values to see if the device is moving ( from the accelerometer ) , or you can use the LocationManager with the source as GPS and locationListener to catch the onLocationChanged event. In both the cases, you can then make use of JNI and implement your algo in C/C++ and interface it with your java code via JNI.
Depending on your needs, if you simply need to know if the device is in motion, i would suggest you use the accelerometer rather than GPS, as GPS would take time to get a fix and also wont work indoors.
