[android-developers] Re: Broadcast receiver in foreground activity - not reliable?

Not sure what's going on then... i suggest you add some logging to your activity and receiver and try to see what goes wrong... i'm guessing that when the app is in the foreground a different intent is being sent (maybe because they exit the car mode differently). Not familiar with these situations,.sorry :)

It is registered in onCreate and unregistered in onDestroy of that activity.

in what lifecycle events do you register/unregister this receiver?

I got a user reporting that our app does correctly terminate when the user's device exits car mode, but only when the activity that contains the receiver is not active. If the activity is in the foreground then more often than not our app does not terminate.

The activity is defined as

       <activity

            android:name=".MainScreen"

            android:alwaysRetainTaskState="true"

            android:configChanges="orientation"

            android:label="@string/app_name"

            android:launchMode="singleTask" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

                <category android:name="android.intent.category.CAR_DOCK" />

                <category android:name="android.intent.category.CAR_MODE" />

            </intent-filter>

        </activity>

The receiver is very simple

private BroadcastReceiver undockReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

    if (intent.getAction().equals("android.app.action.EXIT_CAR_MODE")) {

    finish();

    }

}

    };

Is there a reason that the receiver does not work reliably?  Is it bad practice to put a receiver inside the main activity? or does it have to do with the activity flags?
