B4A Library WebkitLibrariesSet (successor to UltimateWebView)

Ivica Golubovic · Nov 24, 2022

IMPORTANT!!!
Library deprecated. Use UltimateWebView2 instead.

UltimateWebView2

A new old acquaintance (UltimateWebView) returns on the first day of 2024. This library is my New Year's greeting to all the members of this really special forum, a forum that doesn't let the good old BASIC programming language go into oblivion. The new library is called UltimateWebView2 and is...

WebkitLibrariesSet is an advanced successor to the UltimateWebView library. Instead of a single library that made up UltimateWebView, the new concept contains a collection of a large number of libraries that belong to the android.webkit class set. Each library that is an integral part of the WebkitLibrariesSet contains from one to at most several smaller classes.

The advantages of this approach are multiple, and I will mention only a part of them:

Each library in the set is independent from the others, but can be used in synergy with each of the libraries in the set.
For your project, you will use only those libraries from the kit that are needed for your project. With this approach, you can reduce the size of your final application compared to the size of the application using a single UltimateWebView library.
In addition to the fact that each library in the kit is independent, each of them can be used with the native B4A WebView. This means that if you do not need to use WebkitWebView (successor of UltimateWebView) with all its options, in that case you can use native WebView in synergy with other libraries in this set.
To use WebkitWebView Custom View (the successor of UltimateWebView), you don't have to use all the libraries from set, but only those that are necessary for your project (while using UltimateWebView all classes from the set of libraries were necessary).

Over time, this set of libraries will be upgraded with new libraries that will contain classes from the android.webkit class set. Also, these new libraries will be independent to use from other libraries in the kit and all will be able to be used with native B4A WebView.

I am aware of the problem you mentioned. The problem is that this library requires the getWebViewClient and getWebChroneClient methods in order to work with the native B4A WebView. The process of reworking the library is in progress, i.e. creating a clone of this library in Eclipse. After that, it will be possible to overcome the above mentioned problems. I hope it will be ready in a few weeks. For now it is possible to use the library for Api 26 and above.

Ok, thank you very much.

I am trying to use the WebkitLibrariesSet library to create a multi-window browser. The problem I encountered is that after the WebkitWebView click hyper link with target="_blank", WebkitWebView successfully creates a new ChildWindow, but the ChildWindow does not load any URLs and is blank. How to get the URL of the ChildWindow or how to let the ChildWindow load the URL? Can anyone help me? Thank u!
