it home reported on september 12 that technology media android authority published a blog post on september 10, reporting that google is promoting the play integrity api to facilitate developers to review whether the application is in an "unauthorized" state.that is, the user did not install or purchase the app through google play.

introduction to the play integrity api

google announced the play integrity api at this year's i/o conference, which mainly helps developers verify whether application installation package files running on legitimate android devices are authorized in terms of interactions and server requests.

sideloading apps on android devices is easy, but it also carries security risks. sideloaded apps may not provide their full functionality, and in some cases, they can even harm the android system through malware or poor coding.

how does the play integrity api determine the legitimacy of an app?

developers use a variety of parameters to verify the legitimacy of the application. it home attaches the relevant information as follows:

is the application installation file recognized by google play?

whether the app was installed or purchased from google play

whether the app is running on an android device supported by google play services

when a developer's app is used on an android device, the play integrity api provides a response to help the developer determine whether these conditions are met.

chatgpt is one of a handful of apps that have adopted the play integrity api, and when users try to access the chatgpt app that has been sideloaded on their device, they will see a google play store interface prompting them to download the app from that channel.
