According to the forum tutorial, I set up a panel, put a webview and a button (btClose) in the middle, when I ran it, I didn't know how to set the refresh of the webview, I only had to clear the cache of the app, I didn't know if the webview had a refresh function
B4X:
Sub Globals
Private pnlWeb As B4XView
Private WebView1 As WebView
End Sub
Private Sub adButton_Click
pnlWeb.LoadLayout("web")
If pnlWeb.Visible Then pnlWeb.Visible=False Else pnlWeb.Visible=True
WebView1.Invalidate
WebView1.LoadUrl("https://www.b4x.com/teach.html")
End Sub
Private Sub btClose_Click
pnlWeb.Visible=False
WebView1.RemoveView
End Sub
