B4A program uninstalls intself

[Helihead]

Hi all,

Using B4A 2.0. I have a program that I have developed and it installs and runs fine on several devices (droid, droid bionic and 7" tablet). If I use it fairly regularly everything is fine. If I don't use it for several days, it will throw an error saying the program is not installed on my device when I try to run it again. The icon will still be there and as far as I can tell, the files are too. I use a database to store data and if I reinstall the app after getting that error, all my data is intact.

This seems to happen on all the devices. Hard to say for sure but it seems to happen if I don't access it for about 5 days but it is not consistent as I have had it persist for over a month at least once.

Any idea why this is happening?

Thanks

Just a thought, but is it installed on the SD card and you experience this problem with the SD card unmounted?

Seems unlikely but that is a very strange problem.

Or possibly related to the Android bug where the OS fails to return the app's installation or cache folder?

I typically do install to the SD card but it also does it if installed internally.

I will research the other suggestion to see if I find anything that seems related.

Thanks

Never encountered such an issue. Are you sure that you don't have any "cleaning" app running?

I have never specifically installed one and have been looking for something similar but no luck.

As long as I use the app every 2 or 3 days it seems to stay forever.

Hi,

Why don't you upload your app here so that others can have a look.

It is something I hope to sell so I'd rather not post it

I have been testing on a droid, droid-x, droid bionic and a 7" tablet. On further thinking through it, the droid bionic is the only one that drops the app so it is very likely the phone and not anything to do with B4A.

Hi
I have not experienced the problem, on my own devices, but 2 of my costumers has complaint, that one of my apps disappears after reboot.
One of them is using a Sony Ericsson SK17i and the other some sort of Droid. Both of them are from France.
I cannot figure out why.
It is only these 2 out of almost 500,000 installs and I therefore hope, that it is their devices, which is the problem.

Kind regards
Jakob
