Notes:
- ALL Content-Providers doe only READ as yet. For the Calendars-Povider i´ll make an update where you can Update Events and Calendars. It is not done as yet. All other Providers except Calendars does not have any update-methods. So you just can READ all the data

- ALL Providers will return a CURSOR to iterate through the results!

As Example i´ll post code to get all Contacts. ALL other Providers can be used similar.

B4X:
Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim contp As ContactsProvider
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("Layout1")
    contp.Initialize("")
    '
    Dim c As Cursor
    c = contp.Contacts
    If c.RowCount > 0 Then
        For i = 0 To c.RowCount-1
            c.Position = i
            LogColor("===========================", Colors.Green)
            Dim colcount As Int = c.ColumnCount
            Log("columns="&colcount)
            For o = 0 To colcount -1
                Log(c.GetColumnName(o)&"="&c.GetString(c.GetColumnName(o)))           
            Next           
        Next
    End If
    Log("Contacts = "&c.RowCount)

Hello!

How can I get the call logs? The class name is the same and when i use the CallsProvider I don't have .getcalls

I guess it must be different.
My guess was right. I used two time the same classname to wrap.

Library V1.1 updated in Post #1

Attached an Example to read the CallLog
