Get request headers at webview

Question

I login by webview and I need to get headers after logging in. I found, that i can get it by using a method "WebResourceRequest.requestHeaders":

 override fun shouldInterceptRequest(
                view: WebView?,
                request: WebResourceRequest?
            ): WebResourceResponse? {
                request.requestHeaders // this method
                return super.shouldInterceptRequest(view, request)
            }

but it allows only for >=21 api version. My application has 16 minversion, are there any other ways to get headers from webview request?

You haven't clearly described your problem. I assume you want to change minimum api of your application in order to use method "WebResourceRequest.requestHeaders". For this you can do this:

Right click on your project file
Select "Open Module Settings"
Go to the "Flavors" tab.

Select the "Min Sdk Version" from the drop down list
