How do I run the GPS function on the Android emulator?

You can use Telnet to connect to the emulator. The emulator console then provides access to coordinate information, network, and other data.

Instructions for using the console are detailed in here. To connect the console, type in the command line as follows.

telnet localhost 5554

You can then use the geo command to set the hardness and latitude. If necessary, up to the instrument's altitude (which is passed to all programs using the gps location provider). Please refer to the link above if you are curious about the details.

Enter the command below to run on the console.

geo fix <longitude value> <latitude value>

If you need data from multiple coordinate systems, you can use the kml file. https://developer.android.com/studio/profile/ddms.html#ops-locationSee this article. I think it's the most explained data so far.
