I have a webview in android kotlin and i want to read this json defined in postMessage . what is best possible way for it?

[dawidhyzy]

google.com or stackoverflow.com

[Kashif]

i tried but not able to find much for postMessage()

[Kashif]

i mostly find answers for showHtml

[dawidhyzy]

This is wrong place to ask such question. It’s not Kotlin specific. Just check the channel topic…

[Kashif]

ok i guess #javascript will be good place to ask

I don’t think so. That channel seems to be aimed at kotlin/js code - which this is not. Though I haven’t used it myself, I recommend looking for an Android slack group like Android United. Best of luck!

look for "@JavascriptInterface" may be it will help

Also try android documentation. Developers.android.com

@JavascriptInterface

annotation and have a when for the method and then put in what you need to do with the json inside
