Come ottenere il conteggio delle righe in sqlite utilizzando Android?

Utilizzando DatabaseUtils.queryNumEntries() :

public long getProfilesCount() {
    SQLiteDatabase db = this.getReadableDatabase();
    long count = DatabaseUtils.queryNumEntries(db, TABLE_NAME);
    db.close();
    return count;
}

o (in modo più inefficiente )

public int getProfilesCount() {
    String countQuery = "SELECT  * FROM " + TABLE_NAME;
    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cursor = db.rawQuery(countQuery, null);
    int count = cursor.getCount();
    cursor.close();
    return count;
}

In attività:

int profile_counts = db.getProfilesCount();
    db.close();
