Ecosystem evolution analysis and trend prediction of projects in Android application framework

The application framework layer in the Android system consists of numerous project repositories, which rely on each other to form a co-evolving software ecosystem. Android's application framework layer provides many useful APIs to millions of Android Apps, so its evolution will affect the robustness and stability of Android Apps. Code dependency analysis technology is a common way to analyze software ecosystems. However, the code size of projects in the Android application framework layer is so huge that ordinary analysis methods are unacceptable due to the excessive resources required.
