One of the features of Android Studio is the Layout Inspector, which lets you know how many recompositions have been executed and how many recompositions have been skipped. However, it is impossible to know which fields have been changed and recomposed, and if it is a large project, the Layout Inspector may sometimes not work or there may be a delay in screen update.

The post discusses the challenges faced while using the Layout Inspector in Android Studio and introduces the open-source plugin ComposeInvestigator as a solution. ComposeInvestigator helps trace recompositions, provides logs for recomposition requests, recomposition processes, state variable value changes, and skipped recompositions. It also offers additional runtime functions and API usage. The post concludes by highlighting the author's understanding of Jetpack Compose's recomposition behavior gained through working on the ComposeInvestigator project.
