Easy to implement Youdao electronic dictionary using Android

Preface:

The content of graduation design, only has the Java Foundation. Never learned Android.

In the spirit of what to learn. It took more than 10 evenings to finish the graduation project.

Of course, the simple solid line of the electronic dictionary function, from beginning to finish did not consider the performance and other issues.

This electronic dictionary data file is good, Youdao API is to analyze Youdao electronic dictionary log file obtained, Offline Collins dictionary is mdict dictionary MDX file conversion (https://bitbucket.org/xwang/mdict-analysis). This is the only highlight of this e-dictionary. Because I always thought the data was more important than the interface.

The following are examples of core files:
