大型sqlite数据库需要很长时间才能在Android Delphi XE7中加载

Question

我使用Delphi XE7 TSQLConnection连接到大型SQLite数据库并将其部署在android上，它可以工作，但是当我在android上启动我的应用程序时需要很长时间才能加载，如何缩短加载时间

数据库有3个字段编号，文本，文本包含大约28,000条记录

这是我的代码和屏幕

procedure TForm3.FormShow(Sender: TObject);
begin
     xxxConnection.Open;
end;


procedure TForm3.XxxConnectionBeforeConnect(Sender: TObject);
