Android Question Custom View Error, What's is wrong with my code?

[incendio]

Hi guys,

I have CustomView compiled with B4A 11.8, that raised error :
java.lang.RuntimeException:
Object should first be initialized
(Java Object)

But, error only raised in specific phone with Android 11. Other phones, included others OS, not error raised.

Customview is added via Layout.

Here are the codes for Custom View

Sub Class_Globals
    Private EventName As String 'ignore
    Private CallBack As Object 'ignore
    Private mBase As Panel
    Private pnlDummy As Panel
    Private left,top,width,height As Int
    Private pnlLv As Panel
    Private lbDB As Label
    Private imgArrow As ImageView
    Private ActiveTxtBoxBorderColor = Colors.RGB(128,0,0) As Int
    Private TxtBoxColor = Colors.ARGB(150,32,32,32) As Int'Colors.ARGB(255,224,224,224) As Int
    Private InActiveTxtBoxBorderColor = Colors.ARGB(200,32,32,32) As Int'Colors.Black' Colors.RGB(192,192,192) As Int
    Private BorderWidth = 4 As Int
    Private KYB As IME
    Private lv As ListView
End Sub

Public Sub Initialize (Target As Object, Event As String)
    LogColor("ini",Colors.Cyan)
    EventName = Event
    CallBack  = Target
  
    KYB.Initialize("")
  
    lbDB.Initialize("lbDb")
    lbDB.TextColor = Colors.White
    lbDB.TextSize  = 16
    lbDB.Gravity = Gravity.LEFT + Gravity.CENTER_VERTICAL
    imgArrow.Initialize("")
  
    lv.Initialize("lv")
    lv.SingleLineLayout.Label.TextSize = lbDB.TextSize
  
    Private bd As GradientDrawable
    Private col(2) As Int

    col(0) = Colors.RGB(105,105,105)
    col(1) = Colors.Black
  
    bd.Initialize("TOP_BOTTOM",col)
    lv.Color = TxtBoxColor' Colors.RGB(48,48,48)
End Sub

Public Sub DesignerCreateView (Base As Panel, Lbl As Label, Props As Map)
    LogColor("create",Colors.Cyan)
    Private CD As ColorDrawable
    CD.Initialize2(TxtBoxColor,7,BorderWidth, InActiveTxtBoxBorderColor)

    mBase             = Base
    imgArrow.Bitmap = LoadBitmap(File.DirAssets,"arrow-white.png") 
    lbDB.Text        = Lbl.Text
    Base.Background = CD
    Base.AddView(imgArrow,Base.Width-40dip,0,25dip, Base.Height) 
    Base.AddView(lbDB,10dip,0,Base.Width,Base.Height)
  
    pnlDummy.Initialize("pnlDummy")
    pnlDummy.Color  = Colors.Transparent
    pnlDummy.Visible = False
    pnlLv.Initialize("pnlLv")
    pnlLv.Color  = Colors.Transparent
    LogColor("1",Colors.Cyan)
  
    Private Act As Activity
    Act = Props.Get("activity")
    Private CD As ColorDrawable
    CD.Initialize2(TxtBoxColor,7,BorderWidth, ActiveTxtBoxBorderColor)
  
    Act.AddView(pnlDummy,0,0,100%x,100%y)
    LogColor("2",Colors.Cyan)
    left   = Utility.GetRelativeLeft(mBase)
    top    = Utility.GetRelativeTop(mBase)+mBase.Height
    width  = mBase.Width
    height = lv.SingleLineLayout.ItemHeight
    pnlDummy.AddView(pnlLv,0,0,0,mBase.Height)
    pnlLv.Background = CD
    pnlLv.AddView(lv,0,0,0,pnlLv.Height-2dip) 
    LogColor("3",Colors.Cyan)
End Sub

On those codes above, LogColor("3",Colors.Cyan) never reached.

I am confused, because on others phones with same/different OS, no error raised.
Can not get a hand of a phone because it is belong to a user.

So, what's wrong with my codes.

Post the full error message in release mode.

That is the full message.

I use try & catch and use MsgBox(Lastexception.message,"") to catch the error.

 

[Erel]

1. Code with Msgbox = broken code.
2. Remove the try / catch and get the full error.

How to get full of error without try & catch? I don't have that phone.

Without try & catch, app just quit without any messages.

Use the ExceptionEx wrapper from my Threading library to get the stack trace.

Ok, codes modified to use ExceptionEx wrapper.

Must wait for a couple days before get user response again about the app.

Will post the result.
