There aren't any to my knowledge. There are some videos floating around that demonstrate a PTAM implementation on Android phones from a korean university, but it hasn't been released yet.

As far as I know there is no framework for sensor based (using GPS, accelerometer, magnetometer) AR yet. The framework exist only support marker-based augmented reality.
But you can use Wikitude API or create it from scrath. There is an example of sensor based augmented reality here. You can try to learn from it and you can also download the code example.
