Visual Studio + Xamarin: Create database SQLite

I'm trying create a database on my application (Xamarin.Android). I'm using this tutorial http://ift.tt/1Ijk6hm

but the site don't explicate about parameter to path on

private string createDatabase(string path)
{
    try
    {
        var connection = new SQLiteAsyncConnection(path);{
             connection.CreateTableAsync<person>();
             return "Database created";
    }
    catch (SQLiteException ex)
    {
        return ex.Message;
    }
}

Can anyone help me, with this parameter?

I try with "/app1/databases/dbPEduc.db" but show the Exception:

SQLite.SQLite3+Result.CannotOpen
