The newer versions of Android by default back up all user data from all apps in the cloud and restore them on app reinstall. At first glance it's a great service for free.
Now if you happen to be a developer, who stores some app settings and data on the device and through his advanced skills managed to mess up said data and hopes to clear the mess through an app reinstall is in for a big surprise.

Wouldn't a factory reset clear the data?

Yes, but it would make the debugging process somewhat slower. Anyway, there is an opt-out attribute in the app manifest file, but I still wonder why it is enabled by default.
Oh and let's not forget it is in the cloud. I didn't really bother to factory reset, but theoretically after a factory reset the messed up data is in the cloud and would happily apply as soon as you log in to the google drive.

Because it is data, and therefore money.

What cloud? Are you assuming that all Android users stay logged into Google?

Well, yes, it is like a virtual hard drive. I keep music, documents etc there. It is automatically on the whole time.
It's a really nice feature, but now I have to write some code to reset app data on all read exceptions.

Is there a way to disable this? If not, I will definitely think twice about an Android phone. I absolutely hate automatic crap like that.

I know I can disable it in the app manifest(config, which I will do next version), so that the app will tell the backup service not to bother. But I don't think you can disable it globally on the device.

Hasn't allowBackup been around since about v6?

Yep since API 23. It's just that I never managed to generate a bug that would matter in this scenario.

You do not need to uninstall to clear the data (at least on my Android.)
Go into Settings, then Apps. Select the app then select Storage and you should have two buttons, one clears the cache the other clears the data and cache.

That's exactly what I did, but I can't expect the users to figure out that they will have to do the same. The app wasn't able to find the device in the database because it was sending wrong credentials. Basically the scenario is:
you want to track if the app is started for the first time, then get some credentials, store them on the device. You can't rely anymore on the lack of something that is stored there after the first start.
And it is working as intended on older devices. Anyway it is taken care of now, just one more thing to keep in mind.

Actually, agile done right is awesome! It's the work that dictates when a release can be cut, and not the other way around. At my company, release points are dev driven.

How the hell else can it be done? If the dev (which I interpret as developers) say it's not ready than only a full-on jackass would release it (or someone who works for Microsoft).
The difference, in reality, between agile and real programming is that real programming is driven to produce a working product and agile is driven to give management types lollipops as often as possible. A management/marketing point of view designed for the satisfaction of someone who doesn't do the work.

My boss has heard enthousiastic stories about Docker and now wants to use it for distributing Windows applications (both .NET and .NET Core). I never could get enthousiastic about Docker as it can not run Winforms applications, but I decided to give it a chance. Made a simple .NET Core console "Hello World" test application and in VS2017 used Add - Docker, built it and to my surprise everything built on the first try.
Nevertheless when I saw the size of the image with Windows Nano server, more than 400 Mb, my enthousiasm was gone again.
Am I the only one who can not get enthousiastic about Docker, is it me?
I would like to know what your opinion is on the matter

My opinion on Docker for Windows[^]
RickZeeland wrote: Am I the only one who can not get enthousiastic about Docker, is it me?
I haven't seen any advantage, though we (at the company) might be looking at Docker with AWS to spool up additional servers as load increases. The problem with that is we're heavily embedded in ASP.NET and given the above, running Windows in Docker is probably a horrid idea.

Back in the day, we could write an executable that consumed less than 500 bytes that could take down a major city's power grid.
