Android Question Solved - How do I find this bug in my app

[tsteward]

I'd appreciate some help narrowing down / finding what view or whatever it is causing this crash.
Something to do with a B4Xbitmap not being initialized but I just can't find it.

but I just can't find it.

the error is in the b4xmainpage module in the B4XPage_Appear sub.
You are using a b4ximageview and assigns a picture where the crash occurs.

This is the stack trace:

The only bitmap if HamburgerIcon
I have code exactly as in this post from Erel

In B4XPage_Create I Have

#if b4a
    HamburgerIcon = xui.LoadBitmapResize(File.DirAssets, "hamburger.png", 32dip, 32dip, True)
    #End If

Private Sub B4XPage_Appear
    #if b4a
    Sleep(0)
    B4XPages.GetManager.ActionBar.RunMethod("setDisplayHomeAsUpEnabled", Array(True))
    Dim bd As BitmapDrawable
    bd.Initialize(HamburgerIcon)
    B4XPages.GetManager.ActionBar.RunMethod("setHomeAsUpIndicator", Array(bd))
    SetActionBarCustomViewState(False)
    Dim cs As CSBuilder
    Dim tmpuser As String = ""
    If Options1.IsInitialized Then
        tmpuser = Options1.Get("UserName")
    End If
    If tmpuser = "Username" Or tmpuser.Length < 1 Then
        cs.Initialize.Color(xui.Color_Red).Append("Welcome ").PopAll
    Else
        cs.Initialize.Color(xui.Color_Red).Append("Welcome " & tmpuser).PopAll
    End If
    SetSubtitle(cs)  'subtitle can be text also
    #end if
    If B4XComboBoxRecent.IsInitialized Then
        If B4XComboBoxRecent.SelectedIndex = 1 Then
            btnRefresh_Click
        End If
    End If
    MessagesCheck
    
End Sub

Private Sub B4XPage_Appear

Is this the complete code from the event? The question is whether the “setHomeAsUpIndicator” function uses a B4XImageView, otherwise the error message with the code makes no sense.

 

[tsteward]

Yes this is the complete code

 

[tsteward]

I'm really in a bind here with 1.3K crashes effecting 512 users and I just don't understand why

 

[tsteward]

I managed to get it to crash on my wifes phone in debug mode and get the following error
Suggesting the problem is in XUIViewsUtils or my use of it I guess.

[tsteward]

and this is unfiltered log if it helps

 

[klaus]

Line 66 in XUIViewsUtil is: ImageView.SetBitmap(Bmp)

'Sets a bitmap and sets the gravity to Fill.
Public Sub SetBitmapAndFill (ImageView As B4XView, Bmp As B4XBitmap)
    ImageView.SetBitmap(Bmp)
    Dim iiv As ImageView = ImageView

Check the lines where you use XUIViewsUtils.SetBitmapAndFill(ImageView, Bitmap)
Either ImageView or Bitmap seems not to be initialized.

 

[tsteward]

Found it - THANK YOU both for your help
It was infact a bitmap I declared earlier not working so I added the losdbitmap directly on the line that was faulty.

I'll look into it further tonight.
Found it by putting log statements everywhere until I found where it crashed
