@jr
I’d recommend using the applicationDirectory and not the applicationStorageDirectory if you want stuff to be deleted during uninstall.

@Jugger,.

I think this is a windows OS specific problem. It deletes the file on MAC OS I ll verify it on windows though

Is there a way to delete the applicationStorageDirectory on uninstall?

On an app I am working on, I must display an EULA popup the first time the app is run. If a user uninstalls and reinstalls, the EULA must be displayed again.

Any ideas?

@Yash
It is not deleted when the application is uninstalled. Is there a solution for this? Thanks!

@Tony, If the file is placed in the appstorage directory (may be assets folder), it gets deleted when the application is uninstalled. With this you can first test if file exists or not. If it doesn’t than it means its a fresh install or reinstall and you can safely delete the existing db file.

This also doesn’t take into account the fact that the user may have had the app installed before and uninstalled.

I am unable to find a way to get around this.

>Is it possible to save data to a Local SharedObject in AIR?

Yes, you can use either a local shared object, or the encrypted data store.

Either would work, and are pretty good at storing name / value pairs.

Yeah, you could use locate SQLite DB, sharedobjects, or the encrypted data store, although I think that the DB would be overkill (and more complex than it need to be).

Would it not be wiser, while a bit more complex, to use either
1. The local SQLite database
2. The encrypted local store
to store this type of information. Then it could possibly be less likely that the user will delete it. I know that I am usually less likely to delete a .db file in a program directory than a .txt file that I can easily open and look at.

Or perhaps it could be possible to create a “temporary” database that could persist through multiple sessions? That way the information would never even get saved out to a file

Simple enough…Is it possible to save data to a Local SharedObject in AIR? Either that, or some form of “OS-standard” preference file? Coming from (minimal) Cocoa programming experience, it’s pretty easy to save preference data to a .plist file. It’s almost as easy as using an LSO… Just wondering if a mechanism like that exists for AIR, which might be a little more fool proof than just writing a single file to an almost arbitrary location, but instead in the user’s preference directory.

Just kinda thinking out loud.
