White Screen when visiting a certain website on android webview

Question

I'm creating an app that needs to be able to go onto certain websites in order to inject javascript onto those websites. However, the website that I need to access does not load when I try to. This is my activity's code

import android.content.SharedPreferences;
import android.media.audiofx.BassBoost;
import android.preference.PreferenceManager;
import android.support.v4.content.SharedPreferencesCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class ConvergintActivity extends AppCompatActivity {

    WebView webView;

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

        webView = (WebView) findViewById(R.id.convergintWebView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.clearSslPreferences();
        webView.loadUrl("https://infoshare.convergint.com/login.php");
        webView.setWebViewClient(new WebViewClient() {

            public void onPageFinished(WebView view, String url) {
                // do your stuff here
                SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
                String username = sharedPrefs.getString("convergintUsername", "");
                Log.e("Debug!", "Username = "+ username);
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url)        
            {
                view.loadUrl(url);
                return true;
             }
        });
    }
}

The webpage I'm trying to load is https://infoshare.convergint.com/login.php. Why will www.google.com load but infoshare.convergint.com/login.php won't? How can I fix this problem?

Answer 1

Are you trying to load the page in your webview? You should set shouldOverrideUrlLoading() to return false.

However,you could add this settings and,

webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

To check error response in Webview, add this in your WebViewClient method

@Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error){
                        //do something here
}
