It would be possible to create a directory in the directory Files to order more files, and then call via code these files?
For example, if I create the directory /Files/MyDirectory/, I would use the following code to load files ... LoadBitmap(File.DirAssets & "/MyDirecotory/", "icon.png").
To get the list of files in Dir.Assets you do this:
B4X:
Dim MyFile() As String
Dim Lista As List
Lista.Initialize
Lista=File.ListFiles(File.DirAssets)
'Lista=File.ListFiles(File.DirAssets & "/mydirectory")
For i=0 To Lista.Size-1
MyFile(i)=Lista.Get
Log(Lista(i))
Msgbox(Lista(i),"")
Next
For a subdirectory in DirAssets try to use this line below. I never created a subdirectory in assets, so try it.
