Hi,

I enabled system:ping and took the phone with me the whole day. My surprise was that the app "crashed" somehow at some point, and it didn't sent pings anymore to my private server.

If I don't open the app manually again, it doesn't send any pings (battery optimization disabled for the app)

Maybe have some kind of auto-restarts in case the app crash at some point?

Hello!

Could you clarify if you saw a message saying "The app crashed," or if it silently stopped working? In the latter case, it is more likely that the system terminated the app - a situation the app cannot prevent.

Because the system:ping webhook performs periodic network requests, it consumes significant battery power. As a result, the system may kill the process after some time unless the device is charging or all battery optimizations are disabled in system settings. Please note that some manufacturers enforce stricter battery optimization rules than others.

The most reliable way to prevent the app from being killed is to keep the device plugged into a charger, leave the screen on with the app in the foreground, and disable any battery optimization features on your phone. Alternatively, you can rely solely on FCM (Firebase Cloud Messaging), as a push notification will start the app if it isn’t already running.
