Android Question [SOLVED] GpsStatus APIs not supported, please use GnssStatus APIs instead

[yfleury]

On my tablet, my app run well. I install it from usb (B4A)

I run my app for 2-3 month now and google map run well.
last night I submit my app on google play for my tester team.
On my phone, I install a newer version from my web site via an autoUpdate in app.
and today, I have this error

starter_startgps (java line: 213)
java.lang.UnsupportedOperationException: GpsStatus APIs not supported, please use GnssStatus APIs instead
    at android.location.LocationManager.addGpsStatusListener(LocationManager.java:1998)
    at anywheresoftware.b4a.gps.GPS.Start(GPS.java:103)
....
....

When installing, a warning from installer, from google protect.

I uninstall it and connect my phone to usb and install it with B4A in release mode.
All installation was in release mode.

Why this change from gps to gnss?
It working well before this error

You must have set your target SDK to 31. GpsStatus class was deprecated in API level 24 and I think they must now be enforcing the deprecation.

You can use the GNSS libary above but make sure that you do not have a GpsStatus event Sub in your code as its presence will cause this error. Test this with the demo in the GNSS library archive by removing Sub GNSS_GpsStatus near the bottom of Starter.

Ok I find what going wrong.
Before I have this error, my app have targetSdkVersion="30"
I change it to targetSdkVersion="31" then the error on post 1 appear
So, I set targetSdkVersion="30" and my app run well.
Then I set again to targetSdkVersion="31" and comment this sub

'Sub GPS_GpsStatus (Satellites As List)
''    CallSub2(Tous_Les_Plans, "GpsStatus", Satellites)
'End Sub

I don't use this sub before anyway. And my app run well now.

In futur, I know I will need to use GNSS library

Thanks guy, you make my day.
