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 Alternately, the app might be experimental, under development, or perhaps no longer maintained and offered by its developer.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.
the google store environment is such a pain, at work we have android based Zebra barcode readers... today when I was sideloading our app one of the devices kept uninstalling it because of google play... what a fucking pain in the ass
only when intune fully took it over did it stop...
DONT MAKE ME LIKE INTUNE GOOGLE.... JFK
Did you turn off Play Protect?
And yeah, when we set these barcode scanners up, unfortunately it made me appreciate Intune's Android management tools. I despise Microsoft and Google, but Microsoft won that round of "Who do I hate the least right now?"
I had a workflow that I designed in May and then we had to wait for the fiscal year to turn over before we could get another batch of the new style of devices. Between May and this week, Microsoft and Google must have made some changes because my workflow didn't work as directed. I hadnt needed to disable Play Protect for that initial workflow. I just waited until the Intune enrollment was clearly done (policies and profiles were completed in Intune) before I did the customization of the device with abs and such, that seemed to make the other devices go according to plan.
John F. Kennedy?
He'd probably try eating the stupid thing!
