Hello everyone and thank you very much for your time. Before writing my question I came up with possible solutions, I researched and could not find a solution.
I have a WebView in Android Studio in which I wish through the WhatsApp api ( link .) open, worth the redundancy, WhatsApp ... but I can not, I do not achieve any successful result.
It should be noted that for example it does work for me to use the aforementioned api in a common browser such as Chrome. The question / s is / are: do I have to make modifications to the WebView code? Do I need special permits? What is escaping me?
Please, if someone can help me, I would be very grateful. Again, thank you for your time in reading my problem.
