Question

Answer 1

The update() function returns how many rows were affected. So if there were none, you know that you must insert instead:

void updateIfExistsElseInsert(...) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = ...;
    values.put( /* all except the ID */ );
    int rows = db.update(KEY_TABLE, values, KEY_ID + " = " + id, null);
    if (rows == 0) {
        values.put(KEY_ID, id);
        db.insert(KEY_TABLE, null, values);
    }
}
