Solution: Create Contact

    the b4a phone library contains read only access to the contacts.
    but how about writable access? people often asked, but statement here was that it is not possible.

    But after a little bit research in this forum i mentioned that b4a has a very good support for external libraries. It seems, that almost all lower functions are loaded from an external library.

    So i wrote an library (the first in my live ;) ). Using it is is really easy:

    Sub Button1_Click

    'Add libs phone and my miscUtil
      Dim mu As miscUtil, c As Contact
    Dim name As String, phoneNr As String, phoneType As Int, mail As String, mailType As Int
    'define contact data
      name = "Mike Tester"
      phoneNr = 
      phoneType = c.PHONE_HOME
      mail = 
      mailType = c.EMAIL_HOME
    'create contact
      mu.createContactEntry(name, phoneNr, phoneType, mail, mailType) 
    'thats all folks :-) 
    'check success, new contact should be the last entry in the list l
      Dim cs As Contacts
    Dim l As List
      l = cs.GetAll
    For i = 0 To l.Size - 1
       c = l.Get(i)

    End Sub
    Sourcecode and binary of the lib are attached in
    Copy miscUtil.jar and miscUtil.jar to your libraries folder.

    b4a testproject is attached in

    Version 1.01 of the lib is available.
    Add Contacts with multiple email-adresse and/or multiple phone-numbers

    'Add libs phone and my miscUtil
      Dim mu As miscUtil, c As Contact
    Dim name As String
    'define contact data
      name = "Kuno Maier"
    Dim phones As Map, mails As Map

    'create contact
      mu.createContactEntry2(name, phones, mails)
    Suggestions welcome.

    Thanks this is exactly what I need.

    One suggestion the name of the library implies that it does many different functions, maybe call it something more descriptive.

    cheers Waz

    The zip file doesn't seem to contain a new version of the library only 1.0 , so your new example does not work :(

    Oh sorry for that, v1.04 is attached now.

    But it has even improved. You can read and write the photo of the Contact.

    This is exactly what it does for me. It provides all needed different functions for my app, not available directly in b4a. But only contact-management is interesting for common.

    Brilliant, will be trying this later. Very much appreciated, am trying to use this as part of a contact widget so will be great having the new abilities. Thanks :)

    Quick question as a bit curious.

    I use this code:

      phones.Put(c.PHONE_HOME, number_entry_home.Text)
      phones.Put(c.PHONE_WORK, number_entry_work.Text)
      mails.Put(c.EMAIL_HOME, email_entry.Text)
      mails.Put(c.EMAIL_WORK, email_entry.Text) 
    ' save same email for both entries
      ' create the new contact
      name = name_entry.Text

    Null, phones, mails, """"""NullNull)
    where I pass Null for the values of the photo, and the home and work addresses , but when the compiled app runs I am told that the map must first be initialised.

    As the only maps used are initialised in the above code does this mean instead of passing Null as a value is not allowed.

    I tried creating maps but still had Null for the picture value and instead then get error about "no such element". Is there a way to pass Null for the aspects of the contact we do not have such as the photo or home address as it looks like if not all details are filled in the contact can't be saved?

    Thank you for the hint, i will permit Null instead Maps in the next version.

    For now please use initialized Maps (they accept empty strings if you dont know adresses)
    Your Code could be like:

    Dim adressehome As  Map
    0"")  'town
    adressehome.Put(1"")  'zip
    adressehome.Put(2"")  'street
    adressehome.Put(3"")  'country
    Dim adressework As  Map
    0"")  'town
    adressework.Put(1"")  'zip
    adressework.Put(2"")  'street
    adressework.Put(3"")  'country

    Null, phones, mails, """""", adressehome, adressework)

    Thank you for that, I have amended the code accordingly and it works great :)

    Hi optimist,

    Here is something for your lib.
    Delete all contacts.

    public Boolean DeleteAllConcacts(){
    ContentResolver cr = this.m_ba.context.getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
    while (cur.moveToNext()) {
    String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
    Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
                catch(Exception e)
                   return false;

          return true;

    I wonder if there is going to be an option to create a GROUP in contacts.

    Looking good so far.

    Get the Version 1.06 or higher and use createGroupEntry("MyNewGroup")

    Sub CreateGropTest

    Dim MyGroups As Map

    Dim j As Int
    Dim mu As miscUtil

    'lets explore the current available groups
      MyGroups = mu.GetGroupMap
    For j=0 To MyGroups.Size - 1
    Log("Group " & MyGroups.GetKeyAt(j) & " - " & MyGroups.GetValueAt(j) )

    'create the new group
    'lets explore the current available groups again
      'map shold contain the new group now
      MyGroups = mu.GetGroupMap
    For j=0 To MyGroups.Size - 1
    Log("Group " & MyGroups.GetKeyAt(j) & " - " & MyGroups.GetValueAt(j) )

    End Sub

    I would never, never call this function in real live, because i collected my contacts over a log time. :)

    Attached new version v1.06 contains your contribution. Thank you.

    FANTASTIC!!!, simple yet useful, thanks, so far is working fine.

    Question, this lib is for the address book only right?, you cannot add entries to the calendar correct?

    In the future, will this allow to delete a single or selected entries?, deleting the whole contacts list will be rare, but single entries might become useful.

    Yeah, i know. But i needed it for one of my backup apps. Its working cool!
    Its more strange when you do a backup and restore it over the others, that way you get double entries. :sign0142:

    I need to add several (hundred) numbers to one contact. Is that possible with miscUtil?

    No, and currently not planned in the free lib. But i am ready to prioritize special features for sponsors.
