I've been trying to use this bluetooth library to make connection to a little bluetooth module easier. Problem is, when I change my MainActivity from extends AppCompatActivity to extends BluetoothActivity as shown in the example, my app consistently crashes. I've narrowed it down to only this - I can leave all of the abstract functions blank or in their original forms, and it still crashes. Not really sure what to do here.
Could it have to do with versions? It seems to be a memory error, but the abstract methods don't interfere with any of the other objects in the activity.
Edit: Additionally, I do have
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
in my AndroidManifest.xml
