Android WebView App Crashing

Question

I recently make a WebView App for my website and i have a few versions of it but i like this the best. On the tutorial guy video, it all works 100% Great but on mine tho, theres tons and tons of errors that i had resoved. Now one left, the app crashes every single time i tried to start it. It will show for 2 seconds and then closed.

Here's the stack trace :

I think inside of super.onPageFinished view is not same of Webview view. See the following working code.I mean it should be mWebview.

mWebView.setWebViewClient(new WebViewClient() {
   @Override  
   public void onPageFinished(WebView view, String url) {
      super.onPageFinished(mWebView, url);

   }  

   @Override
   public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

   }
   });
   mWebView.loadUrl("your url");

After overwriting my exsisting code with yours, it gave me a lot of error. Can you gave me like the a clearer view? or did you have any exsisting WebView app that has fixed back button and link is opened on the same URL but external ones open on chrome? – PlanetCloud Aug 22 '17 at 09:06
What kind of error did you receive? Actually I dont understand what you want? Do you want back button and click it return previous page ? Or you have webview and it has a link than click this link open in webview if it is external than open it in chrome ? – slymnozdmrc Aug 22 '17 at 10:52
