HP Prime Android Application (2016.12.08 1.3.1.11226) is clearing user apps/programs

[Han]

On the hardware, pressing [Shift] [On] does more than turn off the calculator. It saves the memory state (from RAM to flash, if I am not mistaken) so that when you turn it back on, all of your calculations history, programs, etc. are still there.

I do not know if this is behavior is duplicated in the virtual calculators (though your observations suggest that it does more than just turn off the screen). I do know, however, that the virtual calculator is NOT supposed to do a memory reset after closing the app and then at a later point, opening/running it again.

What was unclear is that this was unable to be reproduced on my end with any devices. However, I've just found some information on a site that *on some devices* the place that the saving of calculator data was happening currently could sometimes be bypassed due to the way those devices allow you to "close" a running application.

In short, the steps provided DO seem to now save properly for most devices, but it is possible that using certain ways to "close" might still be problematic as you've identified.

I've mad a change that should resolve it as well for your case.


Yes, the SHIFT-OFF will manually force a "save". It will now happen in the android onPause() lifecycle call which should be perfectly acceptable for the Prime app.

I have Nexus 6 with android 7.0 and HP Prime 1.3.2.11456.

1. I launch HP Prime from desktop shortcut
2. I tap system square softbutton at bottom right of the screen
3. Within a list of running apps I wipe HP Prime from this list
4. I launch HP Prime from desktop shortcut again
5. All content of HP Prime is gone
   

On what devices you were tested it? I think I have OS as pure as it can be because of Google (without any third party modifications).

I am travelling so I can't test it on anything but a personal phone, but doing that on my nexus 6p (up to date) results in no lost data and it correctly hit the "saving" code. Only thing not saved it the active running command line (which would be expected)

Anyway, I'm pretty certain the issue has now been resolved so should be in the next update whenever that is.

[chromos]

Thank you for answer, Tim.

To clarify, that is WITH the released version in the store on my phone. It does not show that wiping like you describe.

It seems the ver. 11505 fixed behaviour of wipping user's data due "improper" exiting the app, at least on my Nexus 6 with android 7.

Glad it seems to be working for you.

Has anyone else in the beta who previously had this problem verified it no longer is problematic?

[grsbanks]

I'd be interested in joining the beta for this app. I have the paid version. Who do I contact?

[Tim Wessman]

Hello,

The new version that just went live should resolve this issue. Let me know if anyone sees otherwise.

11505 seems perfect IF I remember to shift-off before quitting. But one slip and everything's gone.

A local backup is easy to make, so I do that after entering any important data or program.

[Jan_D]

I have the same experience as normeE.

But is has become a habit of mine to start with shift-on, close with shift-on and sometimes even intermittedly pressing shift-on, and this way I have no problems.

And the back-up possibilities are good.

Are either you signed up in the "beta"? There is one more thing to be tried here in the code to stop this from happening.

Not yet. I did ask who to get in touch with in order to do so. I already have the Pro version on my S7 edge.

[Tim Wessman]

Send an email to calcbeta@hp.com with your store type (google play/ios), and associated email address with your account.

Also, if you are one of the people having this problem, let us know as well so we can ping you directly to see how its going. Thanks!

The problem of losing all content on incorrect closing the app has completely been solved in version 11586 on my Samsung Galaxy tablet, Android 4.4.2.
