First thing I would do, is reading the tutorials.  
[https://android.processing.org/tutorials/sensors/index.html](https://android.processing.org/tutorials/sensors/index.html)  
Then I would google a bit.  
[https://forum.processing.org/one/topic/android-processing-and-serial.html](https://forum.processing.org/one/topic/android-processing-and-serial.html)  
Then writing/adapting my own code…

I have used the Ketai library successfully to communicate using serial over Bluetooth:
