Android Issue with Retrofit and RxJava

I get a following error when I call subscribe on an Observable that was returned from retrofit api call.

I think it might be a Proguard issue. After much googling, I didn't find any fixes.

Versions used

Retrofit used 1.6.1

RxJava used 0.16.1

Let me know if more information is needed.

I've fixed it.

The problem was that rxjava-core and rxjava-android were old versions.

Change from:

compile 'com.netflix.rxjava:rxjava-core:0.16.1'

compile 'com.netflix.rxjava:rxjava-android:0.16.1'

To:

compile 'com.netflix.rxjava:rxjava-core:0.20.3'

compile 'com.netflix.rxjava:rxjava-android:0.20.3'
