Android various third-party wheels

1. Image loading
   It is strongly recommended to give up Universal Image Loader, which has not been updated for a long time.
   We recommend Fresco from Facebook, as well as Picasso, or Glide.
2. Network request
   OKHttp, Retofit, or Volley.
   If there is not much demand for requests, you can consider the Android Aync HTTP that comes with the system (does anyone really use this thing...)
3. Data parsing
   Gson, FastJson, HtmlParser, Jsoup.
4. The database
   OrmLite is based on reflection and lacks Chinese documentation.
   GreenDao is strongly recommended, it has a lot of data, supports encryption
   realm, cross-platform, and supports encryption.
5. Dependency Injection
   dagger2, ButterKnife, Android Anotations
6. 图表
   WilliamChart, MPAndroidChart
7. Background processing
   Tape, Android Priority Job Queue
8. Event Bus

9. Log

    In fact, Android already provides test frameworks such as JUnit.
    There are also these third parties: Mockito, Robotium (UI testing), Robolectric

    Memory leak detection: LeakCanary
    's own tools are as powerful as they are: TraceView, GPU/CPU/Memory/Network Monitor, Hierarchy Viewer, etc.
