I want to open the contacts list in Android. I think the code really makes sense for me, but the emurator always show unexpectedly stop.
Please anyone help me out.

Thanks
Addion
Cursor C = null;
try{
C = managedQuery(Contacts.People.CONTENT_URI, null, null, null, null);
startManagingCursor(C);

}catch (Exception e) {
Log.e("ERROR", "ERROR IN CODE:"+e.toString());
System.out.println ("error--------------");
}


String[] columns = new String[] {People.NAME};
int[] names = new int[] {R.id.row_entry};

mAdapter = new SimpleCursorAdapter(this, R.layout.main,C , columns, names);
setListAdapter(mAdapter);

is it dying in the Adapter?

Thanks for replying me.
I debug and I found my cursor was null.
so it counld not show anything. I want to know why.


THanks in advance
Addion

I changed my code like this, but it still got error at "C = managedQuery(Contacts.People.CONTENT_URI, null, null, null, null); "


public class TestDatabase extends ListActivity {
Cursor C = null;
ListAdapter mAdapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

C = managedQuery(Contacts.People.CONTENT_URI, null, null, null, null);
startManagingCursor(C);

String[] columns = new String[] {People.NAME};
int[] names = new int[] {R.id.row_entry};

mAdapter = new SimpleCursorAdapter(this, R.layout.row, C, columns, names);
setListAdapter(mAdapter);
}
}

I'm not an expert on this but it may be that you need to setup permissions in the Manifest file to use the contact. take a look at the android docs on this.

: java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.ContactsProvider uri content://contacts/people from pid=2

I fixed it after I added READ_CONTACTS permission.
