APK
The installation package format for Android applications, containing compiled code, resources and manifest files. Users can install it through app stores or sideload it via third-party channels.
Timeline (last 90 days)
An APK file typically contains one or more DEX files, the AndroidManifest.xml resource manifest compiled into binary XML, and signature information.
The author early on packaged the AI key inside the app APK, but later, because APK contents can be extracted, switched to Firebase AI Logic, so that the app contains no key, combined with App Check to ensure requests come from the real app.
This installation method is essentially a PWA or APK sideloading mechanism, and apps installed via sideloading do not go through the Play Store security review.
APK sideloading requires enabling the permission to install apps from unknown sources in the phone's settings.
Android has long allowed users to directly install APK files via sideloading, and developers have been able to distribute apps directly without going through the official app store.
APK (Android Package) is the standard packaging format for Android apps, a compressed archive containing the app's code, resources, and configuration files.
The Android system natively supports sideloading—that is, directly installing APK files without going through an app store—a feature that the iOS platform does not have.
The so-called randomly selected APKs are actually screened selectively to ensure that the cases are of moderate difficulty and have pedagogical value.
