I am using rxjava and rxvolley on my android aplication. When I try to run it I get this error
Execution failed for task \':testapp:transformResourcesWithMer
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
