android - Gson库的引用

Question

项目中用到了retrofit网路请求框架，然后json解析系添加了
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
感觉已经够用了，但是为什么看到有的项目中还要添加gosn库
compile 'com.google.code.gson:gson:2.6.2'

Answer 1

The one above is a package repackaged by retrofit itself, while the bottom one is Google’s official GSON package. A situation often occurs where retrofit is used, and then some third-party projects are used that rely on official Gson development projects, and then there is no All methods can only be used. This is a problem that often occurs when using third-party open source projects.

Answer 2

You should just pass the code that references converter-gson:2.1.0'. It may be that the compilation tool defaults to using Google's gson package after seeing gson.

Answer 3

Default relies on gson and uses gson to parse json. You no longer need to reference the gson library separately

Answer 4

1. The dependency of converter-gson is transparently transmitted, so that the dependency of gson is automatically added.
2. You can use @aar to turn off transparent transmission
