Web Browser Is Not Showing Anything

Anyone can take a look at my code and let me know what I am missing? MainActivity.java: public class MainActivity extends AppCompatActivity { private WebView mWebView; pr

Solution 1:

Replace

mWebView.setWebViewClient(newWebViewClient() {
        @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            mWebView.loadUrl("https://google.com");
            returntrue;
        }
    });

With

mWebView.setWebViewClient(newWebViewClient() {
        @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, WebResourceRequest request) {

            returnfalse;
        }
    });

Give the host application a chance to take control when a URL is about to be loaded in the current WebView. If a WebViewClient is not provided, by default WebView will ask Activity Manager to choose the proper handler for the URL. If a WebViewClient is provided, returning true causes the current WebView to abort loading the URL, while returning false causes the WebView to continue loading the URL as usual.

Solution 2:

So far from what I can tell you are supposed to extend the WebViewClient class with a separate class:

privateclassMyBrowserextendsWebViewClient {
      @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, String url) {
         view.loadUrl(url);
         returntrue;
      }
   }

and then set it to the WebViewClient:

mWebView.setWebViewClient(newMyBrowser());

Also try adding settings for loading images automatically, enabling javascript and setting scrollbar:

@OverridepublicbooleanonNavigationItemSelected(@NonNull MenuItem item) {
    switch (item.getItemId()) {
    mWebView.getSettings().setLoadsImagesAutomatically(true);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        case R.id.navigation_home:
            mWebView.loadUrl("https://yahoo.com");
            returntrue;
        case R.id.navigation_dashboard:
            mWebView.loadUrl("https://google.com");
            returntrue;
        case R.id.navigation_notifications:
            mWebView.loadUrl("https://apple.com");
            returntrue;
    }
    returnfalse;
}

Solution 3:

if you are using android 8+ then you must have to do 2 things.

1. Add this android:usesCleartextTraffic="true" attribute in manifest application tag. AndroidManifest.xml

2. you should override this method.

       mWebView.setWebViewClient(newWebViewClient() {
       @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
   
          view.load(request.getUrl().toString()) 
   
           returntrue;
       }
   });
   

Solution 4:

mWebView.setWebViewClient(newWebViewClient() {
        @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            mWebView.loadUrl("https://facebook.com");
            returntrue;
        }
    });
