Android webview launches browser when calling loadurl

Question

I created an Activity that has a title and a web view in a LinearLayout. In the onResume() method it calls webView.loadUrl(url). The problem is that the activity first shows the title with the rest of the screen blank, then the device browser is launched with the page for the URL. What I want to see is the page being shown in the WebView below the title. What could be the problem?

Edit: Ok, did some further search and found this one:

Clicking URLs opens default browser

It points to the WebView tutorial here.

Just implement the web client and set it.

@Ray, consider writing an answer to this question, if you has found a solution, and accept it. This will help other people with same problem. — HitOdessit, Oct 05 '12 at 09:01
I had an even nastier problem. It turns out, even a *redirect* will load with the browser if a custom WebViewClient is not used. — Jakob Weisblat, Jun 29 '13 at 18:47

Answering my question based on the suggestions from Maudicus and Hit.

Check the WebView tutorial here. Just implement the web client and set it before loadUrl. The simplest way is:

myWebView.setWebViewClient(new WebViewClient());

For more advanced processing for the web content, consider the ChromeClient.

Does this only work for the initial loading? What if you want to navigate the browser from within the app? – logicbloke Dec 22 '17 at 17:08

Oh, classic Googlers.

Make your Activity like this.

public class MainActivity extends Activity {
WebView browser;

@Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // find the WebView by name in the main.xml of step 2
    browser=(WebView)findViewById(R.id.wvwMain);

    // Enable javascript
    browser.getSettings().setJavaScriptEnabled(true);  

    // Set WebView client
    browser.setWebChromeClient(new WebChromeClient());

    browser.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
                }
        });
     // Load the webpage
    browser.loadUrl("http://google.com/");
   }
}

`setJavaScriptEnabled(true)` introduces XSS vulnerabilities into your app. Do not use it if you do not need JavaScript – apex39 Sep 25 '18 at 08:17
The line enabling JavaScript is super important otherwise you'll get `You need to enable JavaScript to run this app.` and googling it will only reveal people having issues with react native and you'll go crazy because JavaScript is already enabled in the browser settings. – Jordan H Mar 28 '19 at 21:43
Wini, you can do smth. like this `@ Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_DOWN) { switch (keyCode) { case KeyEvent.KEYCODE_BACK: if (mWebView.canGoBack()) { mWebView.goBack(); } else { finish(); } return true; } } return super.onKeyDown(keyCode, event); }` – Abduhafiz Nov 20 '20 at 12:37

I was facing the same problem and I found the solution Android's official Documentation about WebView

Here is my onCreateView() method and here i used two methods to open the urls

Method 1 is opening url in Browser and

Method 2 is opening url in your desired WebView.
And I am using Method 2 for my Application and this is my code:

public class MainActivity extends Activity {
   private WebView myWebView;

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

      View rootView = inflater.inflate(R.layout.fragment_webpage_detail, container, false);

      // Show the dummy content as text in a TextView.
      if (mItem != null) {

         /* Method : 1
          This following line is working fine BUT when we click the menu item then it opens the URL in BROWSER not in WebView */
         //((WebView)   rootView.findViewById(R.id.detail_area)).loadUrl(mItem.url);

        // Method : 2
        myWebView = (WebView) rootView.findViewById(R.id.detail_area); // get your WebView form your xml file
        myWebView.setWebViewClient(new WebViewClient()); // set the WebViewClient
        myWebView.loadUrl(mItem.url); // Load your desired url
    }

    return rootView;
}                                                                                               }

If you see an empty page, enable JavaScript.

webView.setWebViewClient(new WebViewClient());
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webView.loadUrl(url);

Try this code...

    //Create new webview Client to show progress dialog
    //When opening a url or click on link

    webView.setWebViewClient(new WebViewClient() {

        //If you will not use this method url links are opeen in new brower not in webview
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

                progressDialog = new ProgressDialog(view.getContext());

Simply Answer you can use like this

public class MainActivity extends AppCompatActivity {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         WebView webView = new WebView(this);
         setContentView(webView);
         webView.setWebViewClient(new WebViewClient());
         webView.loadUrl("http://www.google.com");
   }
}

If you're using webChromeClient I'll suggest you to use webChromeClient and webViewClient together. because webChromeClient does not provides shouldOverrideUrlLoading. It is okay to use both.

        webview.webViewClient = WebViewClient()
        webview.webChromeClient = Callback()

private inner class Callback : WebChromeClient() {
        override fun onProgressChanged(view: WebView?, newProgress: Int) {
            super.onProgressChanged(view, newProgress)
           
            if (newProgress == 0) {
                progressBar.visibility = View.VISIBLE
            } else if (newProgress == 100) {
                progressBar.visibility = View.GONE
            }
        }

    }

Damn, it didn't even occur to me to use both. I use `onPageFinished()` from `WebViewClient` and `onConsoleMessage()` from `WebChromeClient`. Thanks! — Sujit, Jun 06 '21 at 10:33

I just found out that it depends on the formatting of the URL:

https://example.com/example gets opened in the browser
https://example.com/example/ (with / at the end) gets opened in the webView

My code just uses

webview.loadUrl(url)

no need to set

webView.setWebViewClient(new WebViewClient())

at least in my case. Maybe that's useful for some of you.

My problem ended up being that I needed to do a clearHistory before I could switch between sites without opening an external browser.

    @Override
    public void onPageFinished(WebView view, String url) {

        webView_.clearHistory();

        super.onPageFinished(webView_, url);
    }
