bluetooth in libgdx project on Android

Can anyone give me a piece of advice about using bluetooth in libgdx games on Android? My problem is that the whole code is in MyGame project and in MyGame-Android there is only MainActivity class that starts the game on Android.

I can get bluetooth to work in normal Android application but MyGame libgdx project can't see classes that are in MyGame-Android project.

Very old question, but I needed kind of the same, so I'm sharing.

I create and app on libgdx and add an implementation to manage bluetooth low energy connections in android and ios. (both are working with a cadence sensor)

All the code is on github if you want

https://github.com/carlgira/ble-cadence-app

I was not sure how the IOS part would work, but basically I translated a Swift bluetooth APP to the robovm java api. There are some differences in names and stuff, but is was almost the same.

In case anyone else finds there way here on their journey to create Bluetooth-able apps. I think the best starting place is the Android Developer guide to get a firm grasp and understanding of Bluetooth on its own - Create a working application with what they have there http://developer.android.com/guide/topics/connectivity/bluetooth.html

After that, using the method above, you can implement the code. A working example is http://algorhymes.wordpress.com/2013/02/07/java-bluetooth-on-android-with-and-wo-libgdx/ but I recommend understanding the Bluetooth first, it makes debugging much much easier.

If you want to use non-multiplatform code in libgdx, you should create an interface on the agnostic project (MyGame), and implement it on the native project (MyGame-Android). Then, on the native project create the implementor object and pass it to the MyGame instance. The interface will hold all the methods that you said are not accessible (a tip: try to can encapsulate the most you can regarding the bluetooth management and expose only methods relevant to your game, so you don't have to create a huge interface).
