SQLiteConnection doen't work. Just wonder why?

I'm trying to run my app with SQLite DataBase.
Data base was created before using the SqliteBrowser.
Just wondering what could it be?

database = new SQLiteConnection(DatabasePath);

This is where it crashes.

    > string DatabasePath {

      get { 
          var sqliteFilename = "KDLife_mobileDB.db3";
          #if __IOS__
          string documentsPath = Environment.GetFolderPath (Environment.SpecialFolder.Personal); // Documents folder
          string libraryPath = Path.Combine (documentsPath, "..", "Library"); // Library folder
          var path = Path.Combine(libraryPath, sqliteFilename);
          #else
          #if __ANDROID__
          string documentsPath = Environment.GetFolderPath (Environment.SpecialFolder.Personal); // Documents folder
          var path = Path.Combine(documentsPath, sqliteFilename);
          #else
          // WinPhone
          var path = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, sqliteFilename);;
          #endif
          #endif
          return path;
      }
  }

This is how i'm trying to get DataBase path.

I'm using sqlite-new and sqlite-net-wp8 NugetPackages.
I use shared project and looks like there is no detailed or any tutorial how to deploy SQLite database to Xamarin.Forms project.
