[enhancement] [feature request] Implementation of "Integrity Check API" #2611

Closed KlausStoertebeker closed 2 weeks ago

KlausStoertebeker commented 2 weeks ago

Is your feature request related to a problem? Please describe. I have some important apps which rely on the play integrity checks, for example my "CamAPS FX" app to control my insuline pump and displaying values of my continious glucose measuring system. As I couldn't get the app run under the alternative operating system "iodéOS" (which uses microg-services) I contacted the developers of the app "CamAPS FX" and they told me that they use the google play integrity checks to ensure that the app was installed from the original Google Play Store without modification and that my smartphone (in my case a "Fairphone 5") isn't rooted or has an unlocked bootloader.

After intensive search in the internet I came to the conclusion that my enhancement/feature request "Implementation of "Integrity Check API"" is a general issue and that there are a lot of topics/issues demanding/requesting the implementation - but I fornd no solution.

Although I saw the issue #2050 "Binding to the service in the play store failed . This is due to having an old play store version installed on the device", I'm not sure which status this issue has (sorry, I'm not familiar with github and moving issues...).

Describe the solution you'd like Implementation of "Integrity Check API"

Describe alternatives you've considered

Additional context

KlausStoertebeker commented 2 weeks ago

Additional information: I used the app "Play Integrity API Checker" and it gives me the following result without executing further tests:

"Error getting token from Google

Binding to the service in the Play Store has failed.

This can be due to having an old Play Store version on the device."

Will this issue be solved by the pull request #2599 "Added Vending IntegrityService" and when will it be available to my "iodéOS"? (I know: silly question - but I really need it to migrate completly to my new smartphone...)

Play Integrity is a major topic that's generally really hard to work on; I've personally spent a week on it to little avail in the past. However, #2599 seems to be in a working state, which is quite impressive. While we cannot provide an ETA, I would personally assume it to land in an official microG release in the next few months.

We have no influence over when your custom OS will include this version in one of its releases.

Hi fynngodau,

thanks for information. Then I hope that it will be available in the (near) future and will close this issue. Thanks for your work :-)

It's expected by December 8, 2024. It is likely that it will be postponed by a few days, though (like what happened with 0.3.4).
