使用Rxjava和Retrofit报错--01

如下所示，编译时报错：

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties
    File1: C:Userslhw.gradlecachesmodules-2files-2.1io.reactivex.rxjava2
xjava2.0.157f850a6b317e5582f1dbaff10a9e7d7e1fcdcfb
xjava-2.0.1.jar
    File2: C:Userslhw.gradlecachesmodules-2files-2.1io.reactivex
xjava1.2.042bfaf64c94f3848ebf5cf1c2ea4ec9d1b3ac6c8
xjava-1.2.0.jar

解决方法：

报错原因是因为依赖错误：

修改如下：

  compile 'com.squareup.retrofit2:retrofit:2.2.0'
    //compile 'com.squareup.retrofit2:adapter-rxjava:1.0.0'
    compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'
    compile 'com.squareup.retrofit2:converter-gson:2.2.0'

修改依赖后注意修改一下代码：
