# Class ContactsManager

java.lang.Object
com.codename1.contacts.ContactsManager

public class ContactsManager extends Object

`ContactsManager` provides access to the contacts on the device for listing, adding and deleting contacts.

The sample below demonstrates listing all the contacts within the device with their photos

    Form hi = new Form("Contacts", new BoxLayout(BoxLayout.Y_AXIS));
    hi.add(new InfiniteProgress());
    int size = Display.getInstance().convertToPixels(5, true);
    FontImage fi = FontImage.createFixed("" + FontImage.MATERIAL_PERSON, FontImage.getMaterialDesignFont(), 0xff, size, size);

    Display.getInstance().scheduleBackgroundTask(() -> {
        Contact[] contacts = Display.getInstance().getAllContacts(true, true, false, true, false, false);
        Display.getInstance().callSerially(() -> {
            hi.removeAll();
            for(Contact c : contacts) {
                MultiButton mb = new MultiButton(c.getDisplayName());
                mb.setIcon(fi);
                mb.setTextLine2(c.getPrimaryPhoneNumber());
                hi.add(mb);
                mb.putClientProperty("id", c.getId());
                Display.getInstance().scheduleBackgroundTask(() -> {
                    Contact cc = ContactsManager.getContactById(c.getId(), false, true, false, false, false);
                    Display.getInstance().callSerially(() -> {
                        Image photo = cc.getPhoto();
                        if(photo != null) {
                            mb.setIcon(photo.fill(size, size));
                            mb.revalidate();
                        }
                    });
                });
            }
            hi.getContentPane().animateLayout(150);
        });
    });

  Modifier and Type
  Method
  Description
  `static String`
  `createContact(String firstName, String familyName, String workPhone, String homePhone, String mobilePhone, String email)`
  Create a contact to the device contacts book
  `static boolean`
  `deleteContact(String id)`
  removed a contact from the device contacts book
  `static String[]`
  `getAllContacts()`
  This method returns all contacts IDs
  `Contact[]`
  `getAllContacts(boolean withNumbers, boolean includesFullName, boolean includesPicture, boolean includesNumbers, boolean includesEmail, boolean includeAddress)`
  Notice: this method might be very slow and should be invoked on a separate thread! It might have platform specific optimizations over getAllContacts followed by looping over individual contacts but that isn't guaranteed.
  `static String[]`
  `getAllContactsWithNumbers()`
  This method returns all contacts that has a phone number
  `static Contact`
  `getContactById(String id)`
  This method returns a Contact by the contact id
  `static Contact`
  `getContactById(String id, boolean includesFullName, boolean includesPicture, boolean includesNumbers, boolean includesEmail, boolean includeAddress)`
  This method returns a Contact by the contact id and fills it's data according to the given flags
  `static Contact[]`
  `getContacts(boolean withNumbers, boolean includesFullName, boolean includesPicture, boolean includesNumbers, boolean includesEmail, boolean includeAddress)`
  Notice: this method might be very slow and should be invoked on a separate thread! It might have platform specific optimizations over getAllContacts followed by looping over individual contacts but that isn't guaranteed.
  `static boolean`
  `isAllContactsFast()`
  Indicates if the getAllContacts is platform optimized, notice that the method might still take seconds or more to run so you should still use a separate thread!
  `boolean`
  `isGetAllContactsFast()`
  Indicates if the getAllContacts is platform optimized, notice that the method might still take seconds or more to run so you should still use a separate thread!
  `static void`
  `refresh()`
  Clears the contacts cache to that they will be loaded from the system the next time `boolean, boolean, boolean, boolean, boolean)` is called.
