Is SQLite cursor.getCount expensive operation in Android

Question

Is SQLite cursor.getCount() expensive operation when executed on Android device?

Which is faster:

Cursor cursor = db.rawQuery(sql, null);
int length = cursor.getCount();
final List<Item> items = new ArrayList<Item>(length * 2); // need maybe 2 items per row

if (cursor.moveToFirst()) {

      // loop trough the query result
      do {
...

or

Cursor cursor = db.rawQuery(sql, null);
final List<Item> items = new ArrayList<Item>();  // capacity is 0 by default on android

if (cursor.moveToFirst()) {

      // loop trough the query result
      do {

Answer 1

If you compare the time required for both code samples to execute, you'll notice it's the same because Cursor.moveToFirst() is eventually calling SQLiteCursor.getCount()
