Android: Content resolver query returning 0 rows when it ought not to

Question

Cursor cursor = resolver.query(
    Data.CONTENT_URI,
    DataQuery.PROJECTION,
    DataQuery.SELECTION,
    new String[] {String.valueOf(rawContactId)},
    null);
         


        

Answer 1

There are a few issues that i could locate with the following query:

Cursor cursor = resolver.query(Data.CONTENT_URI, 
                               UserIdQuery.PROJECTION, 
                               UserIdQuery.SELECTION, 
                               new String[] {username}, null);

1. If all the columns are pointing out at RawContacts table then you should use RawContacts.CONTENT_URI instead of Data.CONTENT_URI.

2. Here the value of RawContacts.SOURCE_ID is compared with username

   public static final String SELECTION = RawContacts.ACCOUNT_TYPE + "='" + 
           "com.tagapp.android" + "' AND " + RawContacts.SOURCE_ID + "=?";
   
   new String[] {username}
