Create Scheduled code every 3 seconds

Question

Hi,

I have the following in my MainPage:

    timer.Interval = TimeSpan.FromSeconds(Preferences.Get("EyeTiming", 3));
    timer.Tick += (s, e) => CheckConnection();
    timer.Start();

and the CheckConnection() is a class in MainPage that checks the Connectivity and saves it inside Sqlite.

How can I move that for iOS and Android to a background process that runs every 3 seconds even when the app is on the background or sleeping?

THanks,

Jassim

Hello,

If you want to execute task in the background service continually. You need to configure each specific platform.

For Android Please check Background Execution Limits in Android 8.0, you cannot run a background service in the background continually. If you can do it by creating a foreground service in MAUI. Then you can add scheduled code in the OnStartCommand method.

For iOS Background tasks are under a strict time limit, and typically get about 600 seconds (10 minutes) of processing time after an application has moved to the background on iOS 6, and less than 10 minutes on iOS 7+, please refer to this document:iOS Backgrounding with Tasks

If your application could be registered following apps.

• Audio
• VoIP
• External Accessories and Bluetooth
• Newsstand
• Location
• Fetch (iOS 7+)
• Remote Notifications (iOS 7+)

Then you can creating Background-Safe Tasks and put your scheduled code in the UIApplication.SharedApplication.BeginBackgroundTask( () => {});
