Scanning for BLE devices on Android 8+ in the background

问题

I'm using the following method from BLE scanner API on Android 8+ to scan for BLE Beacons

startScan(List<ScanFilter> filters, ScanSettings settings, 
PendingIntent callbackIntent)

The problem is that after sometimes I can see Scan Logs but nothing is delivered by the callbackIntent any idea why is this happening?

This is the expected behavior on Android 8+. if you need to scan continuously a periodic mechanism is needed in this case. For more information about scanning on different Android versions and different ways. Have a look here
