tasktimer | Task Timer is a dead simple TUI task timer | Command Line Interface library

I have a function making a callback to other functions in the class in linear fashion.

I want to update a textview in a fragment every 1 second.It is crashing after 1 second. Any help. " android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views."

I've been trying to implement a wrapper class for chrono's high_performance_clock. Basically there is a Diagnostics mother class that keeps a container of TaskTimers. Up until now I have been keeping them as raw pointers in a std::vector list, but reading up on smart pointers and pointer vs object discussions, I'm not sure what to think. It seems results can be in favor or against either, depending on the experiment.

Is there a general consensus of what's considered 'correct' in this case? I'm looking for performance rather than readability.

The Diagnostics class allows the programmer to place timers in any place of the code, as well as start, pause and stop them. They can be accessed by name(std::string) or id(int).

For some reason, the for loop in fromJson method fails to iterate over available JSON fields. The way I understand it (based on the debugging), it is unable to read input string as JSON object. But when I check it in the debugger, I see the correct JSON string. The exact same code works for a different POD class.

The object:

i am testing this signal with a very basic string. But the client side is not firing the server code and there is no error. i added the [HubName("MyHub1")] and the [HubMethodName("GetValueString")] in because if not the javascript will complaint client undefine and methodname not found.

after i added this 2 meta in. there is no error but server code was not fire. Anyone help please.

Client Script

Since my last question I've made my timer program more complex and I've run into another wall. I can't seem to get the display of both timers to update. They print just fine using println but if I use static variables, it gives the correct values but only in the Break timer, which makes sense. So, no matter what I do, I can't seem to figure out how to get the Active timer to update when it should and the Break timer to update when it should. Here are the relevant parts of my code.

Can you provide guidance on how to get the display to update for each as the timer increments?

This class is the functionality of the timer:

My timer is creating a new window with non-working buttons when I hit the start button. The change in display only happens in the new window but the start/stop functionality only works in the old window. I'm not sure what's going on here. Can someone help me figure out how to stop it from creating a new window when start is pressed?

I have three classes I'm working with. The first runs the timer.
