    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            null,
            ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'",
            null,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" COLLATE LOCALIZED ASC");
    while (phones.moveToNext())
    {
        String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        ContactModel contactModel = new ContactModel();
        contactModel.setName(name);
        contactModel.setNumber(phoneNumber);

        contactModelArrayList.add(contactModel);


        Log.d("name>>",name+" "+phoneNumber);
    }
    Log.d("phones", phones.toString());
    phones.close();

    contactAllAdapter = new ContactAllAdapter(this,contactModelArrayList);
    listView.setAdapter(contactAllAdapter);

in logcat thereis nothing

You can try LoaderManager

Create following fields

private static final int CONTACTS_LOADER_ID = 101;

private static final String[] PROJECTION = {
        ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME_PRIMARY,
        ContactsContract.CommonDataKinds.Phone.NUMBER
};

Create follwoing class

public class Contact {

    private String id;
    private String name;
    private String number;

    public Contact(String id, String name, String number) {
        this.id = id;
        this.name = name;
        this.number = number;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

}

[1] Create instance of LoaderManager.LoaderCallback

private LoaderManager.LoaderCallbacks<Cursor> loaderCallbacks = new LoaderManager.LoaderCallbacks<Cursor>() {
        @Override
        public Loader<Cursor> onCreateLoader(int id, Bundle args) {

            switch (id) {
                case CONTACTS_LOADER_ID:

                    return new CursorLoader(
                            getActivity(),
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            PROJECTION,
                            null,
                            null,
                            ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + " ASC"
                    );
                default:
                    return null;
            }
        }

        @Override
        public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
            switch (loader.getId()) {
                case CONTACTS_LOADER_ID:

                   //Use ContactUtils class here


                    break;
            }
        }

        @Override
        public void onLoaderReset(Loader<Cursor> loader) {

        }
    };

[2] Use following class to convert cursor data to List<Contact>

import android.content.ContentResolver;
import android.database.Cursor;
import android.provider.ContactsContract;

import java.util.ArrayList;
import java.util.List;

public class ContactUtils {

    private ContactUtils() {
    }

    public static List<Contact> parseContacts(Cursor cursor) {
        List<Contact> contacts = new ArrayList<>();

        if (cursor.getCount() == 0) {
            return contacts;
        }

        int nameColumnIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME_PRIMARY);
        int idColumnIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID);
        int numberColumnIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

        while (cursor.moveToNext()) {
            String contactName = cursor.getString(nameColumnIndex);
            String id = cursor.getString(idColumnIndex);
            String number = cursor.getString(numberColumnIndex);

            Contact contact = new Contact(id, contactName, number);
            if(!isContactAddedInList(contact, contacts)){
                contacts.add(contact);
            }

        }

        return contacts;
    }

public boolean isContactAddedInList(Contact contact, List<Contact> contacts) {

    for (Contact listContact : contacts
            ) {
        if (listContact.number.equals(contact.name)) {
            return true;
        }
    }

    return false;
}


}

[3] Call getLoaderManager().initLoader method to load contacts in your Fragment or Activity's onStart method

getLoaderManager().initLoader(CONTACTS_LOADER_ID, null, loaderCallbacks);

• Add <uses-permission android:name="android.permission.READ_CONTACTS" /> permission in menifest file
• You need to ask for runtime permission before calling getLoaderManager().initLoader
