Firefox for Android is one of the most widely used browsers. The team is currently involved in reducing the size of the Android Package - APK. As a first step of this ongoing effort the fonts are excluded from being packaged along with the APK. The scope of reducing the size of the APK does not stop there. There are various opportunities and scopes for further reducing the size of APK such as excluding hyphenation dictionaries, translation and so on from being packaged. The task is to download the excluded assets from the server. This initiative can effectively reduce the size of the APK File.I propose to implement features that enables the browser to download the assets like hyphenation dictionaries at the runtime.I also propose to implement a helper class which can be used to smartly schedule the downloads based on the conditions and smartly reschedule the failed downloads and exclude other assets like localization files.
