WebView loadDataWithBaseURL

airblaster · Feb 19, 2013

Is there an equivalent to loadDataWithBaseURL for the WebView?
I'm loading data from an external URL that is not under my control (with permission of course). Without setting the BaseURL images etc are not displayed because relative URLs are used.

Figured it out myself.
In case anyone has the same problem, the idea is:

B4X:

r.Target = WebView1
r.RunMethod4("loadDataWithBaseURL", Array As Object ("http://www.google.de", html, Null, "UTF-8", Null), Array As String("java.lang.String", "java.lang.String", "java.lang.String", "java.lang.String", "java.lang.String"))

LoadUrl should handle relative links correctly.

Sorry, I forgot to mention an important detail:
The html data itself is loaded by a Third Party Android library, so I can't use LoadURL.

Thanks for posting this solution, this was required when we needed to loadHTML from a database that was from a live web site with relative image links. Worked perfectly!

Erel
can the WebView include the above solution within the view to handle baseurl?

Perhaps as a parameter of loadHTML?

Maybe in the future.

For now you can call it with this simple sub:

B4X:

Sub LoadDataWithBaseUrl(wv As WebView, BaseUrl As String, Html As String)
 Dim jo As JavaObject = wv
 jo.RunMethod("loadDataWithBaseURL", Array As Object(BaseUrl, Html, "text/html", "UTF8", null)
End Sub

Thanks

I used the following to solve my issue, is there any advantages or disadvantages between these two techniques?

B4X:

Dim r As Reflector
r.Target = wv1
r.RunMethod4("loadDataWithBaseURL", Array As Object ("http://THEDOMAIN", myHTML, Null, "UTF-8", Null), Array As String("java.lang.String", "java.lang.String", "java.lang.String", "java.lang.String", "java.lang.String"))

No. Both are good.
