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 Alternately, the app might be experimental, under development, or perhaps no longer maintained and offered by its developer.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.

    Androids best advantage used to be full control of the device… Those were the days. Then it started with saying they know better than you, then locking you out. Now I’m waiting on a new, better solution.

    Honestly it’s not like native Linux is too far fetched, but there would have to be a big open source common ground device collaboration.

        Google still allows sideloading, it’s the app developers that can prevent you from installing their app from other sources than Google Play. Sideloading an app works fine on Android if the app’s developer allows it. Apple didn’t allow that even if the app devs wanted it.

          You are technically (and possibly legally) correct… But the spirit of the law is allowing customers to install what they want on their devices.

          This move defuses the responsibility to the developers but EU showed in the past that what they care is the spirit of the law and not the law itself…and they are happy to change the laws to make them more adherent to the spirit

            I would be really happy if you’re right, but I sadly think Google’s fine here. As far as I understand it, this particular regulation is to prevent a powerful actor (Google, Apple) to use their monopolistic powers to shut alternative stores down. It’s not about allowing customers to install whatever and however. Google doesn’t shut anyone down with this, so they should be fine. They give the option for app developers to choose if they want to run only on an attested platform - which they sell as a completely optional security feature that nobody has to use.

            My guess is if the EU is going to take this further it would have to be regarding a potential monopoly on the attested platforms on the device. Google only offering their own platform as trusted could potentially be seen as another monopolistic behavior. If we’re lucky.

              The problem is though that the attested platform only accepts Google play as a store, for this to be truly fair you’d need a way to set a default store setting up and then the attestation API checks that store, but as things currently are it’s giving Google play store an unfair advantage.

Also if your phone supports SD cards, you might notice that you don’t have write access to it for some reason on later versions of android.

    I have an android DAP (music player) that runs Android 7. It’s a box with a headphone jack (remember those?) and it’s sole purpose is to play offline music from an SD card.

    I side-loaded a few music players, because there’s no way I’m putting my Google password in android 7 in 2024.

    I’d be upset if I couldn’t side load. These DAPs never have an up to date android.

        But part of the appeal of Linux is the fact that you can repurpose existing computers running other OSes to run Linux instead. This is a great way to lower the barrier to entry for Linux, because it’s easy to test it on a Live USB or a dual boot. It’s much harder to do this on phones because they have locked bootloaders.

        Another problem is that phones are not productivity devices - they’re consumption devices. Maybe this is just my personal bias, but I don’t think people will be as passionate about liberating their phones because they’re inherently less useful than computers. Convenient, yes, but useful? Not as much.

        That said, I would love to be proven wrong. I would definitely consider a Linux phone if they become more popular/useful, but I can’t really justify spending hundreds of euros/dollars on something for which I don’t see any particular use.

        There aren’t, really. There are a few antiques and half baked things.

        A big problem is that these days, unless you’re the size of Apple or Samsung, it’s impossible to get a reasonable hardware soc and modem other than one which only runs a soon obsolete blob laden android which is going to be EOL before you’ve even finished your design.

        The hardware is not there. The firmware/hw data/platform isn’t there even to begin OS work with. And there’s a global shipping, regulation and mobile operator hell waiting on the other side. And a product lifecycle that’s only a few years long.

        That was the hope with Android, too.

        The problem is that as the OS is “free” that means it costs less functionally for the device manufacturer to get an OS on the device, so now they can pour more money into bloatware.

        Android was supposed to stop bloatware but all it did was enable it.

        Even without a forced “store” Linux is prey to the same issue of piecemeal support from various vendors all with in-house solutions that all stink.

          At this point, even that would be preferable.

          Your right, any open platform will be bastardized eventually, but that doesn’t mean there isn’t still a need for “resets”.

          There is no perfect platform for escaping it, because the market forces will always adapt and assimilate. The only true escape is to keep moving.

          That’s why it’s important for users to be hermit crabs, and move to the next thing, no matter how janky, because they will at least be able to influence it positively and have a relatively open platform for a number of years. Then the cycle repeats.

          If propping up Linux phones will get us the open platform we need, even if only temporarily, we should do it.

          The issue I think is that the current trends in all consumer software are increasingly user hostile, and the major platforms are creating ecosystems to support this. It’s become the norm now to be able to directly control the usage of the software on consumer devices. Apple has normalized this, Google and Microsoft followed.

          At what point will developers refuse to even create software for a system that doesn’t allow them that control?

          Look at how many developers out there absolutely jerk themselves raw at the idea they should be able to compel users to update to continue using their software. Look at how many believe the modern security culture fallacy that handcuffing users and throwing away the key is the only way to protect them.

          It’s a development culture issue. Respecting user control of their own device is no longer in vogue.

          I used it as my daily phone for months, and… well, I’m willing to deal with the problems. Without pretty careful battery management it’s not feasible, and it’s hard to manage your battery given the glitches. I often found my phone dead after a couple hours because it woke the screen immediately after I locked it because… reasons, and then kept it awake until the battery died. The biggest issue aside stuff like that (small issues that cause big problems), the biggest issue was I couldn’t get a map app working. There are some distros with working maps, none for my phone. Also call quality was horrendous. Like. I’m known for being able to tolerate bad quality, but this was, at times, about as bad as I remember my firefly phone being when I was 12, and I could not feasibly understand people at times with that thing.

          But the only reason I stopped using it was because the wifi isn’t working on it. Once I get that back up and running I’ll likely switch back to it. As bad as it can be at times, I still feel more comfortable having that as my primary phone than my Android.

      If someone would be buying those, someone would be selling. You have all the opportunity to fork current android, put it on a different platform, make sure all the drivers are open source instead of blobs, and sell it.

      I’d really want to buy one. But I’ll only do that after you somehow make sure the 3-5 major messaging apps, 2-3 major browsers, and a really good maps app are available.

      So, basically, it’s a 100 mil endeavor for an MVP really. So, I think, the chances of someone actually pulling it off are pretty slim.

          If I go out of my way to root my phone or sideload an app, I have a reason for that. I’m fine with an app going “Hey! This phone is rooted / this app is not from an official source! Wait 10s before you can click ‘I understand and take full responsibikity in case of a security breach’”.

          I’m not OK with an app going “I will not work on this device because yiur environment is non-standard, period”.

      Personally, it’s not Google’s place to dictate how an app verification ecosystem works. If a company has developed an app, they need to be the ones to make sure it’s secure in the first place, not trusting a monopolist tech company that has almost all control with how someone uses their phone.

      Google has rules yes, but Android is open-source and should be open with a free & open market for apps. After all, we paid for the device.

      Why do you think apps should verify their integrity in the first place? In the case of banking apps or other online apps, the APIs they use should be secure in the first place so a user can’t achieve anything meaningful by modifying API calls. In the case of offline games with monetization, a hacker who makes a pirated APK will also remove the restriction so legitimate players on non standart ROMs will get screwed. In the case of messaging apps with a “delete messages” or “one time view” function ie. Whatsapp, the sender shouldn’t take that their actions will be respected by other clients because modded apps exist and Whatsapp doesn’t care if you install it on a rooted device.

        This!

        APK signatures exist and they’re enough for making sure the file you got isn’t modified. Warning people when they use apks for stuff like banking, I get, but if they wanna take the risk, it’s on them.

        Blocking root makes no sense because I’d argue that if the person knows enough to root their phone and got past all those bricked phone/thermonuclear war warnings, the onus is on them to not get their keychain compromised by giving root to some random app. Again, a warning is fine.

        Aside from that, people need to understand: THE CLIENT IS NEVER SECURE. NO EXCEPTIONS.

        Any self respecting secure API is made under the assumption that all the calls are coming from some malicious state actor using curl until proven beyond doubt that it’s an actual user.

        API are secure only if you can secure the authentication details. A modified app (be it as something modified and distributed on a unsanctioned channel, or custom injected by another malicious actor/app) can easily siphon out your authentication tokens to a third party unbeknownst to you the user. However, if the app verifies it came from the approved source and have not been tempered with, then it is much easier to lean on ASLR and other OS level security to make it harder to extract the authentication info.

        Multiplayer game operators have obligation to curb modified clients so their actual paying clients have a levelled playing field. By ensuring their apps are only distributed via approved channels and unmodified by malicious players, this improves their odds at warding off cheaters creating a bad time for those that actually pay them to play fairly.

        These are just simple cases where this kind of security is beneficial. I am glad Android is finally catching up in this regard.

          be it as something modified and distributed on a unsanctioned channel

          Downloading APKs from reputable sources and signature checking can help with this one. Android will refuse to upgrade an app if APK has a different signature anyways.

          custom injected by another malicious actor/app

          If this is possible there are bigger problems.

          Multiplayer game operators have obligation to curb modified clients so their actual paying clients have a levelled playing field.

          There isn’t much I can say for that.

    This seems like a brilliant feature to roll out as they’re getting investigated by the DOJ for being a monopoly.

      I unironically think so. It offloads the blame onto individual app developers. Google can turn around and say oh well it’s what the market wants

      This has almost nothing to do with Google, it’s a feature that has to be enabled by the app developer. Meaning they want to exclude users getting the APK for their app from elsewhere.

        Kinda. It might be 3rd parties using it but it is 100% an API designed by Google to keep apps on Google Play.

          For all we know it could have been requested years ago by developers who have apps that get pirated but there was no mechanism in place to implement it at the time, and wasn’t a priority.

          Just because it’s beneficial to Google maintaining more direct control now, that doesn’t necessarily mean that’s the origin.

            Well, there is a separate system for pirating prevention, the Google Play license check. That has existed for years.

      Also, didn’t the EU declare that Apple needs to allow other app stores on their devices?

      This seems like a bonehead move all around…

        In this case, it seems like it’s the app makers themselves who are requiring the Play Store, though. Unless I’m misreading this, the developers are using the Integrity API to determine if the app was installed through “official channels” (in this case, the Play Store). Feels like people should be upset at the companies behind the apps, here.

          Okay. Then either use older backup versions of those apps before the requirement of the Play Store, or just quit using those apps and services and switch to less enshittified apps and services.

          Easier said than done these days, I know…

          Yes, I know. The point is that people seeking privacy eventually won’t be able to use their banking apps and other online financial accounts unless they’re signed into Google Play to ‘authenticate’ the app.

          AKA force you into letting them steal more of your private info…

            I kinda understand it from the bank’s perspective… They need to reduce risk which is why a lot of banking apps check if the phone is rooted (if it’s rooted, how can you be sure that a malicious app with root access isn’t patching the app in memory and redirecting transfers to a different account?)

            Having said that, I really don’t think they need to restrict it such that the app can only be installed through the Play store, as long as the app is properly signed and uses certificate pinning to prevent MitM attacks.

              Fidelity apps doesn’t require any of this shite?

              But some shiti cash-app does?

              I wonder why 🤔
