By means of this extension we can check if the internet data comes to us through WiFi or through the data network (Mobile data. Cellular). We can also get if "Mobile data" is enabled.
It works with API >= 21
Tested on Android 9.

On this website in Spanish you can find more information and updates:
- Code.
This extension uses:https://developer.android.com/reference/android/net/NetworkCapabilities API >= 21
https://developer.android.com/reference/android/net/LinkProperties API >= 21
The extension code is based on this guide:
This document explains how Android applications can monitor and respond to dynamic changes in network connectivity using `ConnectivityManager` and `NetworkCallback` to get real-time updates on network status, capabilities, and properties.
I have use the nomenclature "Transport" and "Cellular" because it is the one that uses this class (TRANSPORT_CELLULAR).
There are other similar extensions but they don't work with API 29 as they seem to use https://developer.android.com/reference/android/net/NetworkInfo it was deprecated in API level 29.
- Suggestion.
Could someone try this extension on Android 10, Android 11, ...

With companion on Android 11.
I am confused by the result I am seeing from the TransportNet Extension (TransportNet. Check if the data transport comes via WiFi or Cellular ). I suspect this is due to my lack of understanding or expectation rather than a bug
The test app (attached below) checks each of the states:
The check and post procedure:
The clock timer event:
With WiFi off and Cellular data on, I get the following. First, with the app screen active, the alert makes sense: the transport is Cellular and not WiFi and Cellular is enabled:
However on other screens, such as the following browser, the Cellular Transport indicates False:
So far I have only tested this on Android 8 (moto e5 play). Later today I can check on Android 13 (galaxy A14).
Thankful for any help or comments,

WiFiTransport return true.
Clarify, the "get transport" got
WiFi, -56,< unknown ssid>

There isn't a "get transport" block...
The extension is unlikely to return an ssid now due to changes in Android security.

See the documentation for getting the ssid:
Might also be the case if you compile to use TransportNet ?

It seems ok using Taifun. I use the build-in blocks to enable ACCESS_FINE_LOCATION like How do I force a permission to be granted?
Then I tried TransportNet it also work.
Thank you very much!
