Thanks, again, that helped a lot. I've added a menu option (although
I'd love to know how to hide that if I could detect a hardware
button.)
My remaining problem is the search suggestion provider code (which I
took from a 2.0 sample) will compile on SDK 1.5 (I've built a SDK
project to ensure little is hidden by backwards compatibility.)
Anyway, things seem good unless I actually return search suggestions
via a
/**
* The columns we'll include in our search suggestions. There are
others that could be used
* to further customize the suggestions, see the docs in {...@link
SearchManager} for the details
* on additional columns that are supported.
*/
private static final String[] COLUMNS = {
"_id", // must include this column
SearchManager.SUGGEST_COLUMN_TEXT_1,
SearchManager.SUGGEST_COLUMN_INTENT_DATA,
};
The generation is here:
MatrixCursor cursor = new MatrixCursor(COLUMNS, 0);
for (String ingredient : matching_ingredients) {
cursor.addRow(new String[] {
ingredient, // _id
ingredient, // text1
ingredient // intent_data (included when
clicking
on item)
});
}
I've tried reading SearchManager documentation, but cannot seem to
track down what columns it is expecting (or not expecting) for SDK 1.5
that causes it to try to get a long when I don't have one.
Unless I comment that out, I get:

Any pointers on how I'd track down the cause of this problem?
