intent-filter in the manifest does not launch my activity

I'm doing a "new app" within the Set开发者_如何学Ctings app that manages Bluetooth. I have the next problem: I want my activity to be launched when the next android intent is sent by the framework: android.bluetooth.device.action.PAIRING_REQUEST

Due to this, I added this to the AndroidManifest.xml in the Settings app:

<activity android:name=".mybt.MyBluetoohSettings">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
    <intent-filter>
        <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

The problems is that, once that intent is sent by the framework.... my app is not launched!

I've also tried it using just a single intent-filter (with MAIN & PAIRING_REQUEST intents)

In theory this should work, right? What am I doing wrong? Suggestions?

Thanks in advanced!

The Bluetooth pairing request needs to be handled by a Receiver (extended from BroadcastReceiver) rather than an Activity. Your manifest should therefore contain an element, inside <application>, that looks something like this :

    <receiver android:name=".MyReceiver">
        <intent-filter>
            <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
        </intent-filter>
    </receiver>

And somewhere in your application, you'll have a class called MyReceiver :

public class MyReceiver extends BroadcastReceiver {

   public void onReceive(Context context, Intent intent) {

      //
      // Handle the pairing request
      //
   }
}
