问题
I have a strange problem.
I implemented geofencing using Google Services. (Implementation below) On my devices (Samsung Galaxy S and Moto X) they work perfect. On some other devices (HTC Incredible S, Galaxy Note), I receive no transition intents. Never. With great, accurate GPS fix, standing in the middle of fence. Nothing. Nothing suspicious in logs. No errors, no warnings. No itents come, the service does not start.
Have anyone ever seen such a thing? (It is weird because I can't see any connection between devices which work and devices that does not. It's not manufacturer, it's not Android version, Play Services were up to date on all of them.)
Implementation:

}

public ShowNotificationService() {
super("ReceiveTransitionsIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
Log.d("NOTICE", "Android geofence notification!");

Log.e("ReceiveTransitionsIntentService", "Geofence transition error: " + Integer.toString(transitionType));
Crashlytics.logException(new RuntimeException("Invalid geofence transition"));
}
}
}
}
In UpdateGeofences I omitted methods required to connect to PlayServices, since they are basically copied from demo app and I am using them successfully in other places...
Main activity is irrelevant, it just sends broadcast to start UpdateGeofences every time it starts.
GeofenceProvider is also isn't a problem, I am using same code elsewhere with no problems.
回答1:
Eventualy, I managed to fix this by setting exported="true" in ShowNofiticationService.
Like this:
<service android:name="test.package.services.geofences.ShowNotificationService"
android:label="@string/app_name"
android:exported="true"/>
It seems the intents were fired by process with wrong id, and that coused security error. Not sure why would that happen, though...
