My app use retrofit + rxjava run well on Android 5.1 (API 22) system,the aar version is 👍
compile 'com.fasterxml.jackson.core:jackson-databind:2.7.0' compile 'com.squareup.retrofit2:retrofit:2.0.0' compile 'com.squareup.retrofit2:converter-jackson:2.0.0' compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0' compile 'io.reactivex:rxandroid:1.1.0'

but when my app runs on Android 4.2 (API 17) crashed, the crashed report ：

I try to use of a low version of the retrofit 2.0.0-beta3 ，Converter: Jackson 2.0.0-beta3， Adapter: RxJava 2.0.0-beta3 ，but the problem is still not resolved, still crash when running

How can I solve this problem, don't retrofit be compatible with android4.0 as well as the following version?

Please ask usage questions on StackOverflow. Bug reports need executable test cases.

I have tried to search the StackOverflowweb site for the problem, but did not solve the problem。I decided to give up Retrofit, switch to the third party network framework that is compatible with Android2.3.

[JakeWharton]

As evidenced by your stack trace this is not a Retrofit problem anyway

@JakeWharton This is really not the retrofit problem, the really problem is that the Jackson converter is wrong, and now I am trying to use a custom converter.
I hope the custom converter could to be effective , after all, the project is written by using retrofit, if rewrite it by using the other HTTP framework , it's waste of time.
