Android applications are becoming increasingly
popular in digital home nowadays. Building high quality
application is still one of biggest changes for Android developer
community. The search service in current Android application
market can’t meet the needs of developers when trying to find the
user interface design in other applications. In this paper, we
introduce a platform to query the runtime user interfaces of
Android applications, which can help developers to reuse the
design components to improve their applications. Based on the
description information of 8,456 Android applications in Android
market and the information of runtime 313,820 UI elements, we
implement the platform providing search service for developers to
find specified runtime user interfaces in our Android software
repository. Our experiment for the quality of search result shows
that 76.7% of top-10 search result contains the relevant UI
components that are valuable for users.
