Abstract: Android has grown to the world’s one of the largest mobile platforms. Android applications are capable of performing any functionality in the mobile platform. Android applications are also vulnerable to malware. So our goal in this paper is to collect Malware files of generalized Malware Families which will help us as well as other researchers also to conduct experiments for Malware Detection. Here we propose the process for automating browsing and downloading the APK files. We have also developed and implemented our Crawler to automate the process of browsing and downloading the files. We have downloaded Malware and Benign files from the most popular Android Malware Projects. Using this process we have collected around 15508 Malware files and 4000 Benign Files. We have also discussed our Malware Detection process and we have covered the Android File collection phase in this paper.
