Unity 4 Android Game cannot access SQLite DB (C# Script)

I'm currently developing a simply android game and I'm using SQLite as a means to save the high scores in it. When I run it on the editor it works fine and is immediately able to access the data of the table inside it but whenever I have built it into an apk already and run it on my phone it doesn't work anymore. My speculations tell me that the problem is that a connection could not be established to the SQLite database that I added under Assets/StreamingAssets

Likewise I have done a whole bunch of researching already and still no luck. Here's the big bunch of libraries that I am currently using with all the methods possible that I have researched:

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

using UnityEngine.UI;

using System.Data;

using System.Configuration;

using System.EnterpriseServices;

using System.Security;

using System;

//using Mono.Data.Sqlite; (commented out as I thought SQLiteClient would be the fix)

using Mono.Data.SqliteClient;

I have referred to this guide initially: http://answers.unity3d.com/questions/743400/database-sqlite-setup-for-unity.html

as basis for the code for connecting it and it did work in the editor but not when running on my phone.

And here's all the connection methods that I have used so far but off to no success at all D:

1. string conn = "URI=file: jar:file://" + Application.dataPath + "/HighScores.s3db";

2. string conn = "URI=file:" + Application.dataPath + "/StreamingAssets" + "/HighScores.s3db";

3. string conn = "URI=file:" + "jar:file:" + Application.dataPath + "!/assets/" + "HighScores.s3db";

4. string conn = "URI = jar:file:" + Application.dataPath + "!/assets/" + "HighScores.s3db";

5. string conn = "URI = jar:file:" + Application.dataPath + "!/assets/" + "HighScores";

6. string conn = "URI=file:" + "jar:file://" + Application.dataPath + "!/assets/" + "HighScores.s3db";

7. string conn = "URI=file:" + "jar:file://" + Application.dataPath + "!/assets/" + "/HighScores.s3db";

8. string conn = "URI=file:HighScores.s3db"; //Path to database.

IDbConnection dbconn; dbconn = (IDbConnection) new SqliteConnection(conn); dbconn.Open(); //Open connection to the database.

I'm currently using the latest version of SqliteBrowser in order to make the database, create its tables, and populate it with sample data. It creates a file with no filetype and a .s3db file whenever I use its create database functionality. Both of which could have its different set of tables and data which is weird and confusing.
