# Package com.codename1.contacts

package com.codename1.contacts

Provides access to the contacts list from the device address book

The contacts API provides us with the means to query the phone's address book, delete elements from it and create new entries into it.

Notice that on some platforms this will prompt the user for permissions and the user might choose not to grant that permission. To detect whether this is the case you can invoke `com.codename1.Display#isContactsPermissionGranted()` after invoking the contact listing API. This can help you adapt your error message to the user.

The sample below demonstrates listing all the contacts within the device with their photos, notice that this API is very performance sensitive and should be invoked on a separate thread unlike most Codename One API's:

    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);
        });
    });
