A PROF file may also be a baseline profile used by an Android application. It contains precompiled code the app can load at startup and during common user actions, like navigating between screens. Precompiling this code and including it within an app's .AAB file speeds up the app's startup time and overall performance.
More Information
When developing an Android application, developers can optionally create a baseline profile that will be packaged with their app. This profile typically contains app startup code and code that defines how common user interactions function. Usually, developers create these baseline profiles via Android Studio's Macrobenchmark tool.
When a user downloads an app that includes a baseline profile, the receive both the app's .APK file and the baseline profile, saved as a PROF or .PROFM file. During app installation, the Android Runtime performs ahead-of-time compilation for the code included in the app's baseline profile. This allows the app to load this code, and perform common functions, more quickly.
