Programs like xdg-open typically look for a suitable program to open a file with, start that program with the file as argument and then exit.

By the time you get around to checking for child processes, xdg-open has probably already exited.

What happens then is OS dependant. In what follows, I'll be talking about UNIX-like operating systems.

The processes launched by xdg-open will usually get PID 1 as their parent process id (PPID) after xdg-open exits, so it will be practically impossible to find out for certain who started them by looking at the PPID.

But, there will probably be a relatively small number of processes running under your user-ID with PPID 1, so if you list those before and after calling xdg-open and remove all the programs that were in the before-list from the after-list, the program you seek will be in the after-list. Unless your machine is very busy, chances are that there will be only one item in the after-list; the one started by xdg-open.

Edit 1:

You commented:

I want to make the app OS independent.

All operating systems that support xdg-open are basically UNIX-like operating systems. If you use the psutil Python module to get process information, you can run your "app" on all the systems that psutil supports:

• Linux
• macOS
• FreeBSD, OpenBSD, NetBSD
• Sun Solaris
• AIX

(psutil even works on ms-windows, but I kind of doubt you will find xdg-open there...)

DOMException: Failed to construct 'Worker': Script at 'http://136.310.18.216:8070/_apis/xxxx/static/js/WorkerLoadTree.js' cannot be accessed from origin 'null'.

This is a very normal error about access file across domain. Use web worker has one limitation : Same Origin Policy. And also the browser does not allow to create a worker with a URL which pointing to a different domain. This "across domain" error caused by your call way is not correct.

The various XML specifications provide quite a choice of methods for comparing equality; for example XSD has two separate notions ("equality" and "identity"), and XPath has different definitions for the eq operator, for distinct-values(), and for comparing keys in maps. That's just for comparing atomic values; for nodes it gets worse. There's the definition used by deep-equal() in XPath, there's the "is" operator in XPath, and there's equality under XML canonicalisation. The saxon:deep-equal() extends this further, with options to say whether (for example) whitespace text nodes, namespace prefixes, and comments are considered significant when comparing.

Most of these options are available form the Java API by some mechanism, but first you have to decide which one you want.

Instead of fiddling with listdir I would simply use the Glob() method, as provided by SCons itself:

Normally you would want to filter your logs - for example, filter your logs so that you will only see your current application related logs.
Now, if you are debugging error I would recommend to go to your logcat and filter the results by error(it just makes thing a lot comfortable).

In this image, you can see where to filter your log results:

As you can see you can choose what do you want to filter by using this menu.
