Android Question Error: Object should first be initailized

[lock255]

Hi all, in my last app I have a problem, if the compiled in Release (obfuscated) mode, it gives me no error navigazie but then when I go to open a new activity, I have this error:

java.lang.runtimeexception object should first be initialized (listview)

As if I compile in Release mode, I haven't this error.
According to you, this failure may be due to what?

 

[wonder]

Did you add the listview with the Designer or with your own code?

 

[lock255]

In the designer I have add a listview, while I put this in the code:

Sub Globals
    Dim listHelp As ListView
    Dim ForumSupport As PhoneIntents
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("help")
    listHelp.SetLayout(0%x,0%y,100%x,100%y)
   
    'listHelp.AddSingleLine("Support")
    listHelp.AddTwoLinesAndBitmap(Main.L_Support, Main.L_Support_community,LoadBitmap(File.DirAssets,"community.png")) 
    listHelp.AddTwoLinesAndBitmap(Main.L_Donation, Main.L_Donation_info,LoadBitmap(File.DirAssets,"heart.png")) 
    listHelp.AddTwoLinesAndBitmap(Main.L_Contact_us, Main.L_Contact_send_email,LoadBitmap(File.DirAssets,"email.png"))
    listHelp.AddTwoLinesAndBitmap(Main.L_Info, Main.L_Info_app,LoadBitmap(File.DirAssets,"info.png"))
End Sub


Sub listHelp_ItemClick (Position As Int, Value As Object)
    If Value=Main.L_Support Then
    StartActivity(form1)
    Else If Value=Main.L_Donation Then
    StartActivity(form2)
    Else If Value=Main.L_Contact_us Then
    StartActivity(sendemail)
    Else If Value=Main.L_Info Then
    StartActivity(versioninfo)
    End If
End Sub

Which line causes this error?

 

[lock255]

I was not given any error line, only the following message:

java.lang.runtimeexception object should first be initialized (listview)

Run it in debug mode. It will show the line that causes this error.

I also underlined the variables:

Dim btnClear As Button
    Dim btnSend As Button
    Dim lbMessage As Label
    Dim lbSubject As Label
    Dim txtMessage As EditText
    Dim txtSubject As EditText

and as a suggestion on them it says: Variable 'btnClear' was not initialized. (waming#11)

The error line should appear right before the stack trace you posted.
