Run Android App in Background or Background Notification?

Is there any possible way to get a Fusion 2.5 Android app to run in the background, or, is there some workaround to be able to send a notification to an Android device so at least the user knows to open the app?

I have a little app that checks a mysql database every second to see if data has changed. Once it changes, it sends a notification. This works just fine, so long as the Android device is turned on and the app is running. But as soon as the screen turns off the app stops running and it stops checking the database.

If this is 100% impossible though Fusion 2.5, perhaps someone could suggest an alternate option for checking the mysql database every second for a field change?

Many smartphones kill the apps in the background to reduce ram and energy consumption. The solution for you is to have a backend that checks the db and then sends a push notification to the device. This can be done with the onesignal push extension.

Thanks so much for the reply! Are you talking about this extension: Please login to see this link.

Do you know if it comes with any documentation for setting up?

This one is not maintained and doesn't work any more. There is another onesignal extension that i have made for my own needs. Please login to see this link.

There is a small documentation delivered with it, it's very simple to use. The most difficult I think is the backend.

Thank you for the link. It's priced out of my budget for this non-commercial project, but perhaps if I have a client in the future who needs this feature I can justify the cost.
