It is working fine from getting results but I don’t know how to implement the fallowing code in the above example:

ApplicationConstants.phoneContacts
.add(new ContactNumberBean(nameOfContact,
contactNumber, contactNumberType));

If any one know this please help me.

You only need access to an android.content.Context object to access the ContentResolver and thus query ContentProviders. Activity extends Context, so that works. android.app.Service also extends Activity, so that works too. android.app.Application also extends Context, so that will work too.
