Android AltBeacon Library detecting Stoping on Background as Intent - Stack Overflow

I am using the reference app () without any modifications except for the following:

// beaconManager.setEnableScheduledScanJobs(false);
beaconManager.setBackgroundBetweenScanPeriod(0);
beaconManager.setBackgroundScanPeriod(1100);

// Ranging callbacks will drop out if no beacons are detected
// Monitoring callbacks will be delayed by up to 25 minutes on region exit 
beaconManager.setIntentScanningStrategyEnabled(true)

I am testing it with an iBeacon on a Redmi Note 8 Pro running Android 11.

If the reference app is open, it works fine. However, if it is moved to the background (without closing the app), the logcat simply stops printing any logs after about a minute.

As soon as I reopen the app, the log continues, and the iBeacon is detected again.

What could be happening?

I expect the scanning to continue when the app is in the background, but the app simply goes to sleep.

Xiaomi and Redmi branded phones are notorious for killing apps in th background whether they are doing Bluetooth beacon scanning or anything else.

While you are unlikely to get background beacon detection apps working well for general users with on these heavily non-standard Android phones, you maybe able to modify your phone's settings so you can use it for development.

Please try some of the configuration techniques here to see if any of them help. https://dontkillmyapp/xiaomi
