AndroZoo is a large collection of Android applications gathered from various sources, including the official Google Play store. The dataset contains over three million apps, each analyzed by multiple antivirus products to determine if they are malware. The dataset is provided to support ongoing research and to encourage reproducible experiments. The collection was built through a long-term effort to crawl apps from various markets, including Google Play, Anzhi, AppChina, 1mobile, AnGeeks, Slideme, FreewareLovers, ProAndroid, HiApk, and F-Droid. The crawlers were designed to collect as many apps as possible while minimizing impact on market infrastructure. The dataset is available for research, with access conditions that include legal considerations and restrictions on redistribution and commercial use. The dataset is also used for various research purposes, including malware detection, privacy leaks, and application evolution studies. The dataset is continuously growing and is available for researchers to use in their studies. The AndroZoo dataset is a valuable resource for the research community, providing a large, up-to-date collection of Android apps for analysis and study.AndroZoo is a large collection of Android applications gathered from various sources, including the official Google Play store.
