Problem with saving property

function initialize() {
		AppBase.initialize();
		
		if (equals(getProperty("testVar")) != equals("")){
			// DO SOMETHING
		}
		
		//
		//
		//
		
}

I'm trying to call getProperty in the initialization function

It is very important for me that the data stored in memory always remain there. Even if the user starts using another dial, and then returns to mine again, the saved line will not disappear.

That gets called when your main app starts as well as when the background starts.

Print in some println calls and see what you're getting and when.

I try to call getProperty throughout the entire application cycle. I call it in the initialization function, I call it on the onUpdate function, and so on.

If I just got a response, then getProperty returns the correct value.

But if I restart the application, then getProperty on the entire application life cycle returns {default testVar value}, and not what I saved in the previous application session.

The bottom line is that I want to send WebRequest once, get the necessary line and no longer call it, saving the response once and for all.

Put in a bunch of println calls, create a log file on your devices, and see what's happening and when.

You really should only need to get it once when you start and then write it when it changes.  I use Storage for this type of thing all the time.

Okay, then I still have one more question, probably ..

Does using Storage guarantee that the information stored in this way will be saved after the application is restarted, after a crash, and after the application is updated from the store?

It should.  As I said I do this all the time in watch faces and widgets.  The thing is I store the data itself in onBackgroundData so when the app restarts I have that to display.

I will try, many human thanks to you!

No guarantee that the info will be stored and available if app is restarted, crash or after you update or when garmin does batch updates or firmware updates.

You could lose the latest on an app crash or a device crash, but you shouldn't when just restarting an app.  You move to a widget and back, a Wf gets restarted.  You shouldn't lose the data when an app gets updated either. If you do, you meed to look at what you're doing in the app.
