将数据从应用程序传递到控制扩展（smartwatch）

Question

I would like to send some data (string) from Android application to my Smartwatch extension.

I create an Intent in my Main Activity and send it using startService().

From that I understand, I have to override onStartCommand() in a class that extends ExtensionService.

My question is how my class that extends ControlExtension will be notify of this Intent ?

Thanks in advance

Your best option is to use a broadcast receiver. Register a receiver in your control and filter for the intent you send. (Instead of calling startService you should send your intent as a broadcast).

You can create and broadcast your intent with

Intent intent = new Intent("my.super.cool.intent.name");
sendBroadcast(intent)

and then filter with:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("my.super.cool.intent.name");
