I checked your XAML, it works fine – e.g. both labels have a gray foreground. My guess is that you have some style which is affecting the way it looks… Try moving your XAML to a brand-new window and see for yourself… Then, check if you have any themes or styles (in the Window.Resources for … Read more
Basically, there is no such thing as a service type app or functionality in iOS. Even the “background” apps (UIBackgroundMode) cannot run entirely free and without restrictions like a service or daemon etc. on other OSs can. Here’s the situation regarding background execution and notifications and timers etc. 1) An app cannot execute in the … Read more
Have you tried UIApplicationWillEnterForegroundNotification? The app also posts a UIApplicationWillEnterForegroundNotification notification shortly before calling applicationWillEnterForeground: to give interested objects a chance to respond to the transition.

The active window (the result of GetActiveWindow()) is the window attached to the calling thread that gets input. The foreground window (the result of of GetForegroundWindow()) is the window that’s currently getting input regardless of its relationship to the calling thread. The active window is essentially localized to your application; the foreground window is global … Read more
I just noticed that startForeground() doesn’t show the notification icon if the id parameter is set to 0… startForeground(0, notification); // Doesn’t work… startForeground(1, notification); // Works!!! I hope that it could help someone stuck on this.
To achieve a “foreground image” (without extra HTML code), you can use a pseudo-element (::before / :before) plus the CSS pointer-events. The last property is needed so that the user can actually click through the layer “as if it did not exist”. Here’s an example (using a colour whose alpha channel is 50% so that … Read more
