At what point process variables loose their values?

[Penko]

Hello there!

It's a shame, I am having a successful application on the Market and at the same time, it's not very clear to me.

I created a PRO version which is a key only. On the Main Activity of my application, I check if the PRO package is installed and set a boolean variable to True. This controls whether ads should be displayed. What I found out is - at the very beginning, if I start the application, there are no ads. But if I leave the phone away for several hours, when I start the application again, the ads are there.

My question is - if my application is unused for longer(say a couple of hours, or days), at what time do the process variables get back to their default values?

Should I use Activity_Resume of each Activity to ensure that the PRO Check will be handled no matter how you use the application?

Or, if you tell me that I will get FirstTime of Activity_Create, I may be able to use it as well for the PROCheck.

But the thing that is not clear to me - what happens to the values of Process Global variables if the application is unused for some time???

How long an app stays in memory depends on the OS and memory requirements. If 'FirstTime' = True then you know that the app has been out of memory and you may have to re-initialise/load values or the 'State' of the app.

So, it's certain that FirstTime is set to True in the case my application has not been used for quite some time and it's started from its icon?

I see, I'll just to have to reinialize at that moment.
