[AC Question]

I build an android app using Android Studio for my website. I build an Webview and i have 1 little problem. When i press share button from website like Facebook Share login work ok, i press share button but after share is complete i see just a white page.

Here is my main.java

package totalonlinesrl.noiinbucatarie;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.URLUtil;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

private WebView webView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

setContentView(R.layout.activity_main);

webView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
webView.loadUrl("websiteurl");
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if( URLUtil.isNetworkUrl(url) ) {
return false;
}

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity( intent );
return true;
}

});
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack()) {
webView.goBack();
} else {
finish();
}
case KeyEvent.KEYCODE_MENU:
webView.loadUrl("javascriptpen_menu()");
return true;
}

}
return super.onKeyDown(keyCode, event);
}

}
