Hi Erel,

I tried to use the library you uploaded: https://www.b4x.com/android/forum/t...ad-write-access-to-the-stored-contacts.30824/

this is my code(activity_create):
B4X:
    If FirstTime Then
        Activity.LoadLayout("MAIN")
        cu.Initialize
    End If

    Dim FindCo As List
    FindCo.Initialize
    FindCo = cu.FindContactsByName("מקסים",False,False)
    For i = 0 To FindCo.Size - 1
        
        Label2.Text = Label2.Text & cu.GetNameFromId(FindCo.Get(i))
        Label2.Text = Label2.Text & CRLF
        
    Next
and when I runned the app on debug mode, the app crashed.

do you know what is the problem(I Checked line 114 and it was exact as in the project file you uploaded)?

Thanks in advance
