Trying to load the page using Webview. I create html code:

<html> <head> <title>Моя карта</title> <script type="text/javascript" src="http://maps.api.2gis.ru/1.0"></script> <script type="text/javascript"> // Создаем обработчик загрузки страницы: DG.autoload(function () { // Создаем объект карты, связанный с контейнером: var myMap = new DG.Map('myMapId'); // Устанавливаем центр карты, и коэффициент масштабирования: myMap.setCenter(new DG.GeoPoint(82.927810142519, 55.028936234826), 15); // Добавляем элемент управления коэффициентом масштабирования: myMap.controls.add(new DG.Controls.Zoom()); }); </script> </head> <body> <div id="myMapId" style="width:500px; height:400px"></div> </body> </html>

On versions 2.1-2.3.3 of Android, it works perfectly, but on version 4.0.3, it is not possible to load the page. Remains empty webview. How can this be fixed?

  • Strange problem. On the latest version, it should be even cooler than the rest. I advise you to check the installation of libraries and settings. - Anton Mukhin
  • Tried to add to the manifest permishchen access to the network? - Barmaley
  • In the manifesto everything is spelled out. I run the same project on devices with versions 2.1 and 2.3.3 and it works. The same project does not work on 4.0.3 - Maria_1
  • @ Maria_1, To format the code, select it with the mouse and click on the button 101010 of the editor. - Nicolas Chabanovsky ♦
  • Checked in emulator 4.0.3. Through the browser the page is loaded, the map is displayed. Via phonegap I load loadurl, everything is fine too. on a real tablet, too, everything works (in both versions). the error is somewhere near, but not here. - Yura Ivanov

In general, this is not a bug, but a feature, or rather a fixed bug. DoubleGis uses cookies that are not set for about: blank, for it is not security.

In short, you need to replace in your example

 WebView1_H.loadDataWithBaseURL(null, html, mime, encoding, null); //Здесь первый параметр null эквивалентен базовому url about:blank

on something like (literally):

 WebView1_H.loadDataWithBaseURL("http://www.example.com", html, mime, encoding, null);

Tested in the emulator and on a real device.

  • The same goes for localStorage. See StackOverflow: Android 4.0.1 breaks WebView HTML 5 local storage? and android: Issue 16175 . By the way, why do you load html through a string and not from assets? it's easier and easier to debug ... - Yura Ivanov
  • I just started to deal with all this and so far I tried to do everything in a simple way, so I did not go into asset's. Thank you so much for the answer) I suffered a lot with this) - Maria_1

If everything is as you described it, then it draws you to a minor bug report. You can set a bug here . It seems that ICS does not want for some reason to load the script from an external source http://maps.api.2gis.ru/1.0 (although it seems to be available). If the bug is confirmed, then very soon you will receive a response from the Android developers.

PS It is necessary to double-check all the same on other devices. It would be nice if people got rid of the full source code.

  • I checked on the emulator and on the phone with android 4.0.3. Nothing happened. Just a beige screen. Here are the sources of depositfiles.com/files/frc4s53kw - Maria_1
  • @ Maria_1 in the evening, if I don’t forget, I’ll look at both the emulator and ICS device - Barmaley
  • I will wait :) - Maria_1
