How do I use the intent action USER_PRESENT?

Question

I have a clock widget application, and I need to recognize when the phone has been unlocked or not, I believe I can use action USER_PRESENT for that, but I can't get it to launch in the BroadcastReceiver class, I set it in the manifest like this:

    <receiver
        android:name="com.myApp.myApp.MyWidgetIntentReceiver"
        android:exported="false"
        android:label="widgetBroadcastReceiver" >
        <intent-filter> 
            <action android:name="android.intent.action.USER_PRESENT" >
            </action>                               
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/demo_widget_provider" />
    </receiver>

And this is how I trying to get it in the BroadcastReceiver:

public class MyWidgetIntentReceiver extends BroadcastReceiver{

    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals(Intent.ACTION_USER_PRESENT){
            Log.i("TICK", intent.getAction());          
        }
    }

}

It's not firing after I unlock the phone, can you help me out or provide me a better way to check when the phone has been unlocked? thanks!

Answer 1

I got it to work by using registerReceiver in the onUpdate method of the AppWidgetProvider class and passing an instance of the BroadcastReceiver class to register the Intent.ACTION_USER_PRESENT, since adding it only in the Manifest was not doing anything. Thank you!
