Android Tutorial [B4X] RandomUser API - SMM + lazy loading list + DDD

Cross platform example of showing a list of users, retrieved from https://randomuser.me/

The API returns a list with the data of 150 random users. The list is parsed and added to a lazy loaded CLV. The images are downloaded using SMM. Note the usage of the useful DDD (https://www.b4x.com/android/forum/threads/b4x-dse-designer-script-extensions.141312/#content) and the call to DDD.CollectViewsData in the UserCard designer script.

The list performs excellent in Release mode.

The code is short and simple where the most interesting part is:

Private Sub CustomListView1_VisibleRangeChanged (FirstIndex As Int, LastIndex As Int)
    For i = FirstIndex To LastIndex
        Dim pnl As B4XView = CustomListView1.GetPanel(i)
        If pnl.NumberOfViews > 0 Then Continue
        pnl.LoadLayout("UserCard")
        Dim user As UserData = CustomListView1.GetValue(i)
        dd.GetViewByName(pnl, "lblName").Text = user.Name
        dd.GetViewByName(pnl, "lblLocation").Text = user.Location
        dd.GetViewByName(pnl, "lblID").Text = user.Id
        dd.GetViewByName(pnl, "lblEmail").Text = user.Email
        dd.GetViewByName(pnl, "lblPhone").Text = user.Phone
        smm.SetMedia(dd.GetViewByName(pnl, "pnlImage"), user.PictureUrl)
    Next
End Sub

The layout is based on @yiankos1 code (https://www.b4x.com/android/forum/threads/smm-simplemediamanager-images-disappear.169036/)
