使用教程：

 public void Start(IBundleContext context)
 {
      var sdkFactoryService = context.GetFirstOrDefaultService<SdkFactoryService>();
      ISqliteService _SqliteService = sdkFactoryService.GetSqliteService(context, token);
      _SqliteService.DeleteDBFile("test.db");  //删除数据库
      SqliteUtil sqlUtil = _SqliteService.GetSqliteUtil("test.db");  //获取数据库帮助类
}
