Android app: Sending connection status to Activity

[Hephaestus]

We have successfully implemented the Template app on Android. However, the architecture of the multiple services and layers is somewhat opaque. Three questions:

1. How does one send the Battery level to the MainActivity.java?
2. How does one send the Connection Status to the MainActivity.java?
3. Is there a tutorial describing the Android app services architecture? I see them for iOS but not for Android.

Thanks.

To send an event to other activities, you should use the sendBroadcast(..) method. To receive an event, you should use an instance of BroadcastReceiver.

To get an overview of how BLE and works in android, I would recommend you to read the Android "Bluetooth Low Energy" section.
