Apps downloading are what it takes for a mobile phone users a valuable thing if that comes in a larger size as expected but what if the application team itself increase the limit turning the size from MB to a whooping GB – this is what happens for Android applications. Android applications earlier been limited to a maximum size of 50MB – which work for most of apps usually smaller in size – but it do not fit the need for all – so in an urge to make it better, Android app size limit increased to 4GB.
The size of your APK file will still be limited to 50MB to ensure secure on-device storage, but you can now attach expansion files to your APK: Each app can have two expansion files, each one up to 2GB, in whatever format you choose, Android Market will host the files to save you the hassle and cost of file serving and Users will see the total size of your app and all of the downloads before they install/purchase.
Downloading the file on newer devices, the expansion files will be downloaded automatically and the refund period won’t start until the expansion files are downloaded while on older devices, app will download the expansion files the first time it runs, via a downloader library. With an increment over the app size limit, the Android team strongly feels that it will inspire more number of developers to get more creative handy, including for those like 3D graphics, audio and video.
