How to query for contacts information? Docs are not updated to 2.2

[James Elsey]

Hello

I'm working my way through the tutorials on the Android website, I'm looking at the contacts manager

I've also checked out the sample code for this.

I am trying to use managedQuery to obtain various columns of data, such as name, email, postal code.

I have the following snippet of code for doing this, but its currently throwing an error in eclipse

    	String[] projection = new String[] {
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.CommonDataKinds.Email.DISPLAY_NAME
             };

		Uri contacts =  ContactsContract.Contacts.CONTENT_LOOKUP_URI;
		
		//Make the query. 
		Cursor managedCursor = managedQuery(contacts,
											projection, // Which columns to return 
											null,       // Which rows to return (all rows)
                        // Selection arguments (with a given ID)
											null, 
                        // Put the results in ascending order by name
											ContactsContract.Contacts.DISPLAY_NAME + " ASC");

The error that I can gather from LogCat is as follows, not sure how relevant it is to this issue :

I've checked the documenation/examples on the documentation website, but it seems it is out of date (suggests to use deprecated methods and such)

Can anyone please help me with the above code snippet? I can get it to work if I only display ContactsContract.Contacts.DISPLAY_NAME

If you want to get the Name and Email of contacts, then you can use ContactsContract.CommonDataKinds.Email content provider instead of ContactsContract.Contacts provider. See this tutorial too...
