Android BLE scan in background mode of app, Advertisement packets are not detecting beacons are detecting












1














Is anyone have an idea how to solve this problem?
For the long run of BLE scanning. Once the app goes into background mode then app stops detecting advertisement packets.




  • I am using default BLE scan process. with scan filter as BLE device's
    address and beacon manufacturer data.

  • In scan settings, I am using .setScanMode(SCAN_MODE_LOW_LATENCY).

  • I am using android 8 and Android 9 devices.


Thanks

          Oreo has background execution limits.





          • Apps that are running in the background now have limits on how freely
            they can access background services.


          • Apps cannot use their manifests
            to register for most implicit broadcasts (that is, broadcasts that are
            not targeted specifically at the app).





          One way to solve this problem would be to use foreground service, so android system won't kill it.
