Show data from GnssCapabilities.getGnssSignalTypes()

[rapperskull]

I'm developing a method to add L5 functionalities to my device (it is sold in different markets with different capabilities), and I would like to have a way to easily test what is available on my device. I can check if I get L5 reception, but I can't test for NavIC for example, since I'm in Europe.

I saw that there's a getGnssSignalTypes() method in GnssCapabilities, but I didn't understand what's about. If it describes what constellations and bands the device supports, it would be nice to have that information available in GPSTest.

@rapperskull Agreed! This new API is available on Android U and up, and I plan to add support for it to power the Dashboard view of supported signals (see work-in-progress at PR #570). I'm going to close this issue as a duplicate of #313.

Also, please keep me posted on your method to add L5 to your device!

Didn't notice the "Added in Android UpsideDownCake".
By the way, this is my method to add L5 support to the Realme GT 2 Pro:
