Thanks!

Thank you very much

Thank you very much!

Good job...

Thank you 👍

Hi @emil2k , Are there any APIs to check if the WiFi which is connected to, really serves internet or not? whenever the device is connected to WiFi, it considers it as online though the Wifi router does not serve internet or idle. How to check in such situations. I came across pinging some site to detect. But i want to know if there are any APIs which checks the situation.

Thank you so much for this :)

Many thanks man 💯

how to use it..inside MainActivity ? onCreate ? and example please.. many thanks.

How we can check network speed in case of wifi?

Thanks

Nice code, Thanks

Updated the same code with better readability.
