Android: how to access the SIM contact table using the SDK?

Question

I am trying to use this query to read the contacts on the SIM.

            cur = managedQuery(Uri.parse("content://icc/adn")
                ,null
                ,null
                ,null
                ,null
                );

The application has READ_CONTACTS and WRITE_CONTACTS permissions. Yet, the query returns an exception.

java.lang.NullPointerException

What's wrong?

Answer 1

i have used the following code to get the simcard details..It works fine

Uri simUri = Uri.parse("content://icc/adn");
        Cursor cursorSim    = this.getContentResolver().query(simUri, null, null,null, null);

         while (cursorSim.moveToNext()) {           
             listName.          add(cursorSim.getString(cursorSim.getColumnIndex("name")));
             listContactId.     add(cursorSim.getString(cursorSim.getColumnIndex("_id")));      
             listMobileNo.      add(cursorSim.getString(cursorSim.getColumnIndex("number")));
            }

Here the name, _id, number are column names from the simcard table
