There are more than couple of things that you need to do -

1. In your content provider, you need to attach a notification Uri before the Cursor is being returned to client (in this case your Activity). The code would look something like this (Here the Authority URI need to be changed as per your provider) -

if (c != null) { c.setNotificationUri(getContext().getContentResolver(),ContactsContract.AUTHORITY_URI); } return c;

1. Every time there is a update in data, the following line needs to be called -

getContext().getContentResolver().notifyChange(ContactsContract.AUTHORITY_URI, null, syncToNetwork);

Basically what point 1 & 2 does is that it notifies the underlying data layer that there is currently a client with an active cursor and needs to be notified if there is a change in the underlying data. If you are using any of the inbuilt data providers in Android like ContactsProvider/SmsProvider to read contacts/SMS data, point 1 &2 would have been taken care.
