有人要求我继续开发移动应用程序，应用程序使用b4a, my J-D-K版本是1.8，数据库是p-o-s-t-g-r-e-S-Q-L，服务器l-o-c-a-l-h-o-s-t在我的PC上，我尝试应用程序的设备是三星，但是我有一个问题使我无法运行应用程序，首先当我尝试通过三星登录时，它卡住了，无法停止加载，但是当我尝试时X-I-A-O-M-I，加载成功但错误时l-o-a-d-l-a-y-o-u-t-("main")，这是什么问题？有人能帮我吗 ？
这是出现错误的代码
Sub Activity_Create(FirstTime As Boolean)
If Starter.login=False Then
StartActivity(pagelogin)
Activity.Finish
Else
DateTime.DateFormat = "yyyy-MM-dd"
tanggal = DateTime.Date(DateTime.Now)
NowNav=1
Activity.LoadLayout("main")
ActionBar.SetAsActionBar
ActionBar.InitMenuListener
ActionBar.Title = "Smart Campus"
ActionBar.SubTitle = "Tenaga Pengajar"
BuildNavigationDrawer
Homenya
id_gedung.Initialize
Timer1.Initialize("Timer1", 1000)
Timer1.Enabled = True
End If
错误是
