You might sideload an Android app, or manually install its APK package, if you're using a custom version of Android that doesn't include Google's Play Store. Alternately, the app might be experimental, under development, or perhaps no longer maintained and offered by its developer. Until now, the existence of sideload-ready APKs on the web was something that seemed to be tolerated, if warned against, by Google.
This quiet standstill is being shaken up by a new feature in Google's Play Integrity API. As reported by Android Authority, developer tools to push "remediation" dialogs during sideloading debuted at Google's I/O conference in May, have begun showing up on users' phones. Sideloaders of apps from the British shop Tesco, fandom app BeyBlade X, and ChatGPT have reported "Get this app from Play" prompts, which cannot be worked around. An Android gaming handheld user encountered a similarly worded prompt from Diablo Immortal on their device three months ago.
Google's Play Integrity API is how apps have previously blocked access when loaded onto phones that are in some way modified from a stock OS with all Google Play integrations intact. Recently, a popular two-factor authentication app blocked access on rooted phones, including the security-minded GrapheneOS. Apps can call the Play Integrity API and get back an "integrity verdict," relaying if the phone has a "trustworthy" software environment, has Google Play Protect enabled, and passes other software checks.
Graphene has questioned the veracity of Google's Integrity API and SafetyNet Attestation systems, recommending instead standard Android hardware attestation. Rahman notes that apps do not have to take an all-or-nothing approach to integrity checking. Rather than block installation entirely, apps could call on the API only during sensitive actions, issuing a warning there. But not having a Play Store connection can also deprive developers of metrics, allow for installation on incompatible devices (and resulting bad reviews), and, of course, open the door to paid app piracy.
If the Play Store becomes required like that then Android's already-shaky status as an open source base platform is going to go out the window. I'm glad there are non-Google distros of Android but there really needs to be more of a push to make a completely FOSS phone platform.
The more I think about it, this may finally convince me to...shudders...switch to an iPhone. I've always stayed on Android because despite the recent Google bullshit, it still for the most part lets me do whatever. Side-loading apks is a huge part of that.
If it's turning into a shittier iOS clone, what's the point?
Don't do IOS, it's such a pain. It took us 2 days to figure out how to play an audio book file that I was able to download an F-droid app for and play in like 3 minutes.
Yup that sounds about right for iOS.
Meant more that if Android ends up in the same boat (and by the looks of it, that's exactly what Google and Samsung want), then iOS starts to look viable because the situation becomes: all the same bullshit but iOS is polished to a shine.
Don't plan on switching phones until my less than year old Note 9 kicks the bucket 😅
