Which way should I use to get images from gallery? I want the default gallery application to open when I click a button and I can select one or more photos and add them to the CustomListView. Is such a B4X code possible? To make it cross-platform.
On iOS there is an iMedia library that will call...
Dim MB As MediaBrowser
Dim tmp_m As Map = MB.GetMediaImageList(True, "datetaken DESC")
xiv.SetBitmap(LoadBitmapResize(tmp_m.Get("Location" & Rnd(0,tmp_m.Size/7)),"",xiv.Width,xiv.Height,True))
I want to share my class to create a image preview list like in the gallery app.
This class is based on xCustomListView and PreoptimizedCLV.

The cache folder is created here...

Dim Out As OutputStream
Dim r As RuntimePermissions
Out = File.OpenOutput(r.GetSafeDirDefaultExternal("pruebas"), "prueba.jpg"...
