      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_acilisbir);
  
      myBrowser = (WebView) findViewById(R.id.anasayfagetir);
      myBrowser.setWebViewClient(new MyBrowser());
      myBrowser.getSettings().setJavaScriptEnabled(true);
      myBrowser.loadUrl("file:///android_asset/anasayfa.html");
  }
  
   private class MyBrowser extends WebViewClient {
  
          @Override
          public boolean shouldOverrideUrlLoading(WebView view, String url) {
  //This link is work
  if (url.equalsIgnoreCase("Navigation://OpenNativeScreen")) {
                  startActivity(new Intent(acilisbir.this,AnaEkran.class));
                  finish();
                  return true;
               //But this is not
              }else if (url.equalsIgnoreCase("activity_buy://Buy")) {
                  startActivity(new Intent(acilisbir.this,Buy.class));
                  finish();
                  return true;
              }
              return false;
          }
      }
  
  }
  </code></pre>
  
  <p><strong>I'add to my</strong> <code>manifest</code></p>
  
  <pre><code>&lt;activity android:name="Buy" &gt;
              &lt;intent-filter&gt;
                  &lt;category android:name="android.intent.category.DEFAULT" /&gt;
                  &lt;action android:name="android.intent.action.VIEW" /&gt;
                  &lt;data android:scheme="activity_buy" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
  </code></pre>
  
  <p><strong>Html link code</strong></p>
  
  <pre><code>&lt;INPUT TYPE="test" value="Test" onClick="window.location='Navigation://OpenNativeScreen'"&gt;
  &lt;INPUT TYPE="buycr" value="Buycr" onClick="window.location='activity_buy://Buy'"&gt;
  </code></pre>
  
  <p>here the link <strong>targeting the Buy Activity</strong> is not working.I have no error in android studio.But its not starting the BuyActivity when the link is clicked.</p>
