closing webview in android

Question

I am using Twitter4j but I need to authenticate a user with oAuth. The user needs to get a pin and input it into the app. When I load a webview with the url and the user accept's to give the app privileges, they receive a pin. How would they close the webview in order to input the pin. I cant close the webview in the emulator. Below is the method in the Async class where the webview is shown after the url is retrieved.

 protected void onPostExecute(String url) {

        WebView webview = new WebView(MainActivity.this);
        setContentView(webview);
        webview.loadUrl(url);


    }

Answer 1

You can't "close" a WebView. What you could do is hide it. Maybe this solution will shed some light - Hide WebView until JavaScript is done

Answer 2

Well, you could

• instead use another dedicated activity with mainly a webview [potentially also with 'done' button]. You could start that activity from your onPostExecute with intent, and then you will go back when user is done with it, or you could start that webview activity for result

• Another option is to replace your webview when you are done with another view, for example by calling setContentView with another layout. I never did this myself, and not sure it will work easily, but I found that some people recommend using ViewFlipper for similar effect.

Hope that helps.
