At a glance:

1 – Add Sqlite.cs to your project.
2 – Add your database file as an Asset.
3 – Set your database file to build as an AndroidAsset.
4 – Manually copy the database file out of your apk to another directory.
5 – Open a database connetion using Sqlite.SqliteConnection.
6 – Operate on the database using Sqlite.

1. Add Sqlite.cs to your project.

2. Add DB as asset.

3. Set DB to build as AndroidAsset.

4. Manually copy DB out of your APK.

string dbName = "db.sqlite";
string dbPath = Path.Combine (Android.OS.Environment.ExternalStorageDirectory.ToString (), dbName);
// Check if your DB has already been extracted.
if (!File.Exists(dbPath))
{
    using (BinaryReader br = new BinaryReader(Assets.Open(dbName)))
    {
        using (BinaryWriter bw = new BinaryWriter(new FileStream(dbPath, FileMode.Create)))
        {
            byte[] buffer = new byte[2048];
            int len = 0;
            while ((len = br.Read(buffer, 0, buffer.Length)) > 0)
            {
                bw.Write (buffer, 0, len);
            }
        }
    }
}

5. Open DB Connection.

using (var conn = new SQLite.SQLiteConnection(dbPath))
{
        // Do stuff here...
}

6. Operate on DB.
