We are living in the age of the fast and accessible Internet. Our devices are using 4G and WiFi at many places is free. Big images and video files are used to create great designs and impressive user experiences. Heading to the great design, user experience to impress customers, developers and designers can bring into the app big images and video files. So who cares about the size of the app in Play Store?
We do and we must. Good network coverage is usually only in big cities and can be poor in small villages. Google reports that more than half of the Android users in India and Indonesia do not have any access to WiFi. In those markets users have mostly 2G network, where every megabyte counts.
In this talk, I will share our experience of reducing apk from ~70 MB to ~20 MB. We will go through each step and analyze the impact of each action. At the end, we will look how having a small apk affected the number of installations and registrations in the app. More important, we will check the system we established to monitor and prevent the apk from growing again. This talk will be helpful for developers and designers, in order to create a common understanding of optimally building apps.
