Description
Developer Assistant helps developers, testers and designers inspect Android apps directly on a mobile device. It can show an app’s view hierarchy, help verify its layout and style, and preview translations at runtime.
The tool is best suited to apps built with Android Views and Fragments. It also offers limited support for Android Compose, Flutter and web apps, so its inspection capabilities can vary by technology.
You can invoke Developer Assistant with a gesture such as long-pressing the Home button. It uses Android’s Assist and Accessibility APIs, combined with heuristics, to inspect apps while they are running.
