WifiRttLocator and WifiNanScan example apps

[plottsjp]

Google has published the WifiRttLocator, WifiNanScan and WifiRttScan example apps on the google play store, but this repository only has source code for the WifiRttScan app - can you add the other example apps to this repository.

WifiRttLocator: https://play.google.com/store/apps/details?id=com.google.android.apps.location.rtt.wifirttlocator WifiNanScan: https://play.google.com/store/apps/details?id=com.google.android.apps.location.rtt.wifinanscan

Thank you!
