Answer 1

I also have this problem ,I also used the same method as you ,but because I hava two module ,I only chang it in the module which dependency Rxjava,Finally I I fixed it is adding the packaginOptions in app gradle

packagingOptions {
    exclude 'META-INF/rxjava.properties'
}

Answer 2

I encountered the same issue and fixed it by putting below code in app/build.gradle file. Please note that you have to put '*' at the end of path to exclude all the files inside the folder. You will have to change the path of files to be excluded in the below code based on error description.

compileSdkVersion 25
    buildToolsVersion "24.0.3"

    packagingOptions {
        exclude 'com/google/appengine/repackaged/org/apache/commons/codec/language/bm/*'
        exclude 'com/google/appengine/repackaged/org/codehaus/jackson/impl/*'
        exclude 'com/google/appengine/repackaged/org/apache/commons/codec/language/*'
    }

I had this issue today and fixed this problem

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

//RxJava dependencies
compile 'io.reactivex.rxjava2:rxandroid:2.0.0'
compile 'io.reactivex.rxjava2:rxjava:2.0.2'
compile 'org.reactivestreams:reactive-streams:1.0.0'

Answer 4

If you are facing this issue in 2019 and above this is most probably because you are using the deprecated RxJava 2 CallAdapter.Factory ie

com.jakewharton.retrofit:retrofit2-rxjava2-adapter

you will have to remove that dependency and add this

implementation 'com.squareup.retrofit2:adapter-rxjava2:latest.version'

please get the latest version from here

Answer 5

I also have the same problem but easily removed duplicated "comment" all Rxjava related dependencies that it doesn't use in my code.

//RxJava removes or comment duplicated and not used dependencies.
      //  implementation 'com.squareup.retrofit2:adapter-rxjava:2.4.0'
       // implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
       // implementation 'io.reactivex.rxjava2:rxjava:2.1.13'

Answer 6

I had the same issue.
In my case I am using Retrofit2 but I assume that the issue is with the rx libraries

This is the build.gradle (module:app) I am using and in my case works.

compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'

compile 'io.reactivex:rxandroid:1.1.0' //<-use this
compile 'io.reactivex:rxjava:1.1.3'    //<-use this

compile 'com.squareup.okhttp3:okhttp:3.1.2'
compile 'com.squareup.okhttp3:logging-interceptor:3.0.1'

Anyway there is one better solution as you can see on the top
