Ali Android development experience crystallization

In 2017, tmall double 11, the transaction volume reached a new high of 168.2 billion yuan, of which wireless transaction volume accounted for 90%; In December 2017, Dingpin registered more than 100 million users 1,075 days after its birth. During the same period, xianyu users also exceeded 200 million… Faced with such a large number of users and traffic, these apps can still be “silky smooth”.

Behind this is the continuous exploration and optimization of Alibaba mobile development team. Over time, these experiences have been summarized into a set of perfect development specifications, guiding engineers to develop apps with good experience, excellent performance, good stability and high security.

The development specification has been continuously improved in Alibaba, and now it is compiled into a book and opened to Android developers in the industry, hoping to help enterprises and developers avoid detours and improve the quality and efficiency of Android development.
