Android Question Webviev and white page

[coslad]

Hi

i tried this symple code but Always i get a White page :

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
Dim wv As WebView
End Sub
 
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
Activity.LoadLayout("main")
wv.Height=Activity.Height
wv.Width=Activity.Width
wv.LoadURL("www.google.it")
End Sub

Manifest :

AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="26"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
    AddPermission(android.permission.INTERNET)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.

Tested on Android 8 and Android 7 devices , where i wrong ?

maybe u need this runtime permissions at sdk 26?

do you see something in "Check the unfiltered logs:" ?
there is a checkbox beside logs in ide.

No permission is required. Please upload the project.

In attach the project and apk file compiled with B4A 8.3 beta 1, on my Mate 10 pro with android 8 i see only White screen

Works fine once I added http://

Sub Globals
   Dim wv As WebView
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("main")

   wv.LoadURL("http://www.google.it")
End Sub

Sub wv_PageFinished (Url As String)
   Log(Url)
End Sub

BTW, you should use anchors.

Thanks you are right !

but the real problem in the main project was this code :

wv.initialize("wv")
