I think you're going to have to break out the debugger and see. I
dropped your code into my app I set up to verify my response to you
earlier, and made my app1's provider return this cursor:
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
MatrixCursor mc = new MatrixCursor(new String[] { "_id", "roll",
"name"}, 1);
mc.addRow(new Object[] {50, "round", "fred"});
return mc;
}
and up popped up the expected toast -- 50 round fred.
Note, however, that trying to do multiple toasts in a single onCreate
method isn't going to be particularly helpful. You'll just see one,
and only after the method returns. I'd suggest using Log.d instead of
a Toast, and watching the LogCat pane in Eclipse instead. This will
give you more immediate feedback while debugging, and you can see as
much information as you want.
