rxjava2.0+retrofit2.0初试水，小demo

一个简单的post异步。

1.添加依赖

compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'

compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'// 大神写的这个库可以支持到rxjava2.X
//compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'//retrofit现在只支持到rxjava1.XX

compile 'com.squareup.retrofit2:retrofit:2.1.0'

compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

注意横线部分：

//(代码中：addCallAdapterFactory(RxJava2CallAdapterFactory.create())

//添加：compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'错误报异常：Error:

// com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties

//   File1: C:\Users\Administrator\.gradle\caches\modules-2\files-2.1\io.reactivex\rxjava\1.1.5\ece7b5d0870e66d8226dab6dcf47a2b12afff061\rxjava-1.1.5.jar
