Android Question Local web page not showing <img>

anOparator · Dec 16, 2014

Am having major problem loading a local web page, IMG not showing:
1. I can load background images onto Webview:

B4X:

  WebV.LoadHtml("<html><body background='file:///android_asset/image.jpg'></body></html>")

2. I can load webpage onto Webview but the pictures don't show:

B4X:

Sub Process_Globals
  Dim wbpage As String
End Sub

Sub Globals   
  Private wv1 As WebView
  Private Button1 As Button
End Sub

Sub Button1_Click
  wbpage = File.ReadString(File.DirAssets, "mywebpage.htm")
  wv1.LoadHTML(wbpage)
End Sub

I have read:

https://www.b4x.com/android/forum/threads/webview-tutorial.24343/page-2

How to modify the HTML and point to the image in the assets directory?

it works, I tried it 2 years ago but I don't recall how it was exactly.

try to use ./ ../ or something like it to get to the right path. (it won't recognize file:///)

Oops, so much for speed reading, the answer was in:
https://www.b4x.com/android/forum/threads/adding-an-animated-gif-to-your-app.29872/

B4X:

Sub Globals
    Private wv1 As WebView
    Private Button1 As Button
End Sub
Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("imgyes")
End Sub
Sub Button1_Click
wv1.LoadURL("file:///android_asset/awebpage.htm")   ' THIS path works on my Samsung , loads web page w/imgage
End Sub

' File not used (warning #15) if .html and .jpg not added to projects File tab. Can warning be avoided?

Three cheers for B4A

You can add #IgnoreWarnings: 15 to the top of the main module.
