Description

Hi,

I'm trying to get UnifiedNlp to work on my phone running Android 4.2.2. With wifi, everything is working fine with either this backend or the AppleWifi backend. However, it seems that using wifi networks for location positionning under Android 4.2.2 requires having the wifi always on, so I'm looking for a way to rely on cell network.

Using cell network in this backend, I don't get any position. After investigating it a bit in adb logcat, this line always log "Cells: 0" which seems to mean it is not fetching the nearby cells. Not sure why :/

Thanks

Research direction

Start with src/main/java/org/microg/nlp/backend/ichnaea/BackendService.java around line 126 and reproduce the problem on Android 4.2.2 while collecting adb logcat output. Trace why the log reports "Cells: 0" and verify that a cell-only request obtains a position without Wi-Fi.
