A reader asks:

Can Google delete apps from my Android smartphone?

Eh, yes, of course! There’s a push message and a mechanism for that implemented in the Playstore app. In case you find that surprising: how did you think Play would handle a cancelled payment for paid content? Return the money and let you keep the item?

In case the question was if you could buy an app, use Raccoon to download the APK to your PC, then refund, the answer is: yes you can do that (shame on you), most paid apps safeguard against this by performing an online license check.

I’m currently looking at period tracker apps - don’t ask why (it’s an apk downloader thing).

Brilliant business model:

  • Once hooked, users slowly lock themselves in.
  • Automatically tuned to the perfect target audience (young adults;female;medical problem)
  • Users voluntarily disclose the perfect time to pitch them products and services.

Dear women: if you want/need/have to track this kind of thing, make sure to choose an app that a) doesn’t require an internet connection and b) allows you to export your collected data.

Getting more emails from Indians these days wanting to sell me 5 star app reviews on Google Play. Curiously they are all using Gmail addresses for contacting me.

If you are offering to cheat the system (in particular one that’s known for scanning your communication), shouldn’t you use a communication channel that’s outside of the system?

Got two support requests today concerning Google Play and app / device compatibility checking. Updated the docs for dummydroid as a result:

What are trustworthy APK sites?

So, there's this Android app, you really must have, but its developer only distributes via Google Play and, for some reason, Play is off limits to you. How do you get it anyway? Sure, there are tons of APK mirror websites out there, but how do you know which ones you can trust?

Wow, some asshat just spammed me about integrating his SDK in a compiler tool I wrote (and abandoned) years ago. He heard great things about it, felt like telling me that on four different email addresses (none of them related to that tool or each other) and wants to set up a call.

K, buddy, if you insist on working with a scraper database, then you can have the name and phone number of another asshat from my spamfolder who contacted me with a similar proposal the other day.

Trump vs. China. Can TikTok and WeChat really be banned from US based Android devices?

Legal questions aside, let's explore the technical possibilities.

I just had a terrible business idea:

  1. Create a shitty, low effort Android app (dunno, something like a weather widget, horoscope, or calculator knock off).
  2. Publish on Play, let it rot ripen for a couple of months, then buy 100k+ installs (see email spam folder for offers), add some 5* reviews for good measure.
  3. Sell that app to those asshats that keep spamming me about buying my apps for a song.

Yes, those scavengers DO annoy me. Especially when having a disclaimer in their footer, informing me that I received their offer because I subscribed to some mailing list.
