Hi all,
I've been trying to read the contacts list so that I can compare phone
numbers in it against the number on an incomming SMS message.
I've been getting an error that I just can't fix.
The method is:
public String checkContacts(String telNo)
{
String[] projection = new String[] {People.NAME, People.NUMBER};
Uri mContacts = People.CONTENT_URI;
String selection = People.NUMBER + "=" + telNo;
String sort = People.NAME + " ASC";
Cursor managedCursor = managedQuery(mContacts, projection,
selection, null, sort);
startManagingCursor(managedCursor);
if(managedCursor.getCount() > 0)
{
managedCursor.moveToFirst();
return managedCursor.getString(0);
}
else
{
return telNo;
}
}
Output from LogCat looks like this:

If any further information is needed I can easily post it up.
Any advice or guidance would be greatly appreciated.
