Android Tutorial GPS / GNSS tutorial

The GNSS library replaces the old GPS library. The GNSS library is available here: https://www.b4x.com/android/forum/threads/gnss-library-an-updated-gps-library.109110/#content

Using it is quite simple:
1. Checking whether location services are available. If not take the user to the settings.
2. Request permission.

If the purpose is to get the user location then the FusedLocationProvider might be a better option: https://www.b4x.com/android/forum/threads/fusedlocationprovider-resolution-dialog.111652/#content

All GPS programs use the same API to access the GPS. These programs probably use other methods to find the location when the GPS is not available. See ABWifi library: Libraries - Basic4android Wiki

I just cannot download the code. Do I need to pay to get the permission of downloading the code?

 

[Erel]

The trial version doesn't support libraries. This attachment is only available to users who bought Basic4android.

Help for to get GPS coordinates

Hi Erel,

I tried the code you attached.

When I run the program in my Emulator,

I get a message that "GPS device enabled=true".

But i did't get GPS cordinates as out put.

I see we have two more events

Sub GPS_UserEnabled (Enabled As Boolean)
//statements
End Sub 
And 

Sub GPS_LocationChanged (Location1 As Location)
//statements
End Sub

But I understand there is no event executed for GPS_UserEnabled and GPS_LocationChanged.
I printed a message box alert inside there. But I didn't get any alert message from that section.

My GPS Lib version is 1.00 and Core Version is 1.91

Can you help me ; I want to get GPS Latitude and Longitude of current location.

Regards,

Does your GPS find any satellite?

Does your GPS find any satellite?

Yes, I can see my location on google maps.

[Erel]

It doesn't mean that your GPS find any satellite. The location can be based on other sources (not related to the GPS).

How I can get timestamp from gps?

 

[Erel]

You can get the fix time by calling Location.Time. This should be done in the LocationChanged event.

I received 13 digits timestamp from gps. How I can convert this to datetime?

 

[klaus]

The time you get from the GPS library are TICKS and you need to convert it to your needs with the DateTime object.

Best regards.
