Thanks, Erel, but I didn't understand how can that snippet help, in this case.

I tried it, passing a null string as "FromSubName". I get a "long" list of rows (only 21, used in a very small project for tests).
Probably you mean that I should I consider only those lines which start with my app package name.
If I understand well, it shows only the routines called during the use of the application (the user could not use all of them).

BTW, to get those lines, I thought to call that routine (LogStackTrace) at "application end" so now I know that... I don't know "where" a B4J app ends (I mean that I have not found an "app closing" event - I should start a new thread for this question, I know ).


Thank you.

The jAWTRobot library has a method called JVMAddShutdownHook() that allows you to handle graceful JVM shutdowns (that is, when the JVM shuts down under its own power, not when it's shut down by the OS or a Task Manager). This works in B4J UI and non-UI apps.

What are you trying to accomplish, overall? Are you trying to retrieve the stack trace of the Exception that is killing your app? The jAWTRobot allows you to redirect Standard Error to a text file. There's also some improved Exception handling features that will be released soon.

Try this, it's based on code found here: https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html

It shows a lot of methods that you won't be interested in you'll have to pick through. Works better on B4j, but it works for initialized Class objects (not code modules) in B4a, and class names as strings for classes in the API.

Depends on JavaObject and the Reflection lib

If you look at the documentation, there are 4 levels of information. If you change the call from getMethods to getDeclaredMethods, you can lose some of the methods you're probably not interested in (inherited methods).

I've modified it for you, download it again and pass 3 as the infolevel for less info or 4 for all of it. (See the documentation for the differences)

At the moment, I can do it "by hand" (perhaps Erel will do this and I hope that he will change the "modules window" adding a TreeView).

Otherwise, I can accomplish this by acting on the source of the project, using part of my (underestimated ) AddLogs software.


Thank you very much, Steve
