Java Question Wrapper for AppBugTracker android library

[frapel]

I am trying to create a wrapper to the AppBugTracker android library (www.appbugtracker.com) to install an UncaughtExceptionHandler different from the B4A default.

Wrapping the library is not a problem, but after calling the init method of library (that changes the default UncaughtExceptionHandler) this seems not changed or changed again to default handler.

My wrapper create a simple Initialize method that do this:

public static void Initialize(BA ba, String appToken) {

        Context context = BA.applicationContext;
        Logger.setLevel(LoggerLevel.TRACE);

        Log.d("appbugtracker", "before init: " + Thread.getDefaultUncaughtExceptionHandler().getClass().getName());

        com.appbugtracker.AppBugTracker.init(context, appToken);

        Log.d("appbugtracker", "after init: " + Thread.getDefaultUncaughtExceptionHandler().getClass().getName());
    }

before the AppBugTracker.init the value of UncaughtExceptionHandler was anywheresoftware.b4a.BA$1
and after the init call the method value is changed to com.appbugtracker.impl.AbtImplIncidentHandler

I call my Initialize method in Activity_Create method of my B4A application:

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim abt As AppBugTracker
    Dim abtToken As String = “—token-here—“
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
'    If FirstTime Then
        abt.Initialize(abtToken)
        Msgbox("richiamato AppBugTracker.Initialize", "DEBUG")
'    End If
 
    Dim b As Button
    b.Initialize("b")
    b.Text = "Raise Exception"
 
    Activity.AddView(b, 0, 100%y - 50dip, 100%x, 40dip)
End Sub

Sub b_Click
    Dim s() As String
‘  // Raise an exception here, that should use the AppBugTracker handler
    If s(0) = "a" Then ToastMessageShow(“throws exception”, False) Else ToastMessageShow(“ok”, False)
End Sub

But when I click on the button trying to raise an exception the default handler (defined in BA static block) is used instead of com.appbugtracker.impl.AbtImplIncidentHandler as you can see in the attached screenshot.

I have also seen the thread related to ACRA :

http://www.b4x.com/android/forum/threads/trying-to-create-acra-library.19720/#post-113855

but i didn't understand how to override the exception handler.

Hi.

Debug it...
Add a new java method to your library:

public static void LogIt(){
    Log.d("appbugtracker", "LogIt:  " + Thread.getDefaultUncaughtExceptionHandler().getClass().getName());
}

Now in your b4a code:

Sub b_Click
    '    which handler is being used right now?
    apt.LogIt
    Dim s() As String
    If s(0) = "a" Then ToastMessageShow(“throws exception”, False) Else ToastMessageShow(“ok”, False)
End Sub

Do you see the b4a or appbugtracker handler logged?

Currently it is not possible to replace the error handler that handles most errors. This will be changed in a future version.

Thank you Erel. I will wait for that version.

hello
how and where you can create new methods in Java?

 

[DonManfred]

With using inline Java code. Without inlinejava you cannot create New Java methods with b4a
But you can write a wrapper with Java and use this in b4a then

thanks DonManfred
as I understand it, we can re-implement inline functions in the class? For example, I can reimplemtare functions of class "super" an activity?

I explain better what I'm trying to understand and do:
in B4A you can not create derived classes, so I'm trying to find a way to do it in Java and use objects in B4A. In particular, I need to create a class derived from Activity to use in B4A.

You can be done? There are examples that approach (which I did not find)?
thanks
