Question

How can we get info from a webpage(link on it that downloads an excel file when you click on it)? What subjects should be searched in order to do that on Android? Thanks.

Answer 1

AFAIK, you will not able to know what are the link is for. There is a way to know about the link of the webview on which user clicks and it is WebViewClient.

Here is a code using which you can know that the clicked link has XLS file or pdf file or others. You can also block the link using that code

public class TestingActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

      WebView view = new WebView(getApplicationContext());
      view.setWebViewClient(new MwebViewClient());
    }

  class  MwebViewClient extends WebViewClient {
    @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if(url.contains(".xls")) {
            Log.d("Blah", "This link contains XLS file");
        }
        return super.shouldOverrideUrlLoading(view, url);
        }   
    }
}
