Downloader needs to know if version has changed...

[deanott]

The downloader currently queries the databse for apps that have not been downloaded.
It then attempts to download that app and if successful it then updates the database.

I do the downloading updates of the database in batches right now.

There is no way currently with the the downloader tool on the play store to ask for a specific version, this would require another query to check. Do not really want to bring in all the retreiver to the downloader.
If we setup up that we can pass a sort by oldest we could also also remove dates that are too old? reducing only the chance of the version mismatching. Unless we get unlucky and the second we scrape we have a update. @AdamSlack @sauyon thoughts?

Personally i think that we should only really care about the latest versions of apps. By all means we should keep a record of previous play store apps, but maybe it should be in a separate table.

We're wanting to see what is being done with your personal information, its more important to see what they're doing with the latest version as opposed to one you can't download any more from 2 years ago.

That said it would be interesting/useful to know about situations like when a previous app didn't do anything particularly unethical, but then started to do so. that way you could know not to update your app or something.

Our table is setup in such a way that all versions are recorded as per the wishes of the rest of the team (ie Max, mostly).

I think I suggested checking that the last updated was within a reasonable range (2 days?) before downloading the app.

Another possibility is that the analyzer (now that it can identify versions) can simply move the apk to the correct version in the event that the version is wrong.
