Hot questions for Handling EOFException in Retrofit

Retrofit gives EOFException only the first time

Question: I'm using framework Retrofit for the first time in my Android project. It handles communication with a backend. Now the strangest part is that on Android 4.4 everything works like a charm. On every version below. I get a RetrofitError type So it fails the first time and then when I push on the retry button it works. So Why is it failing the first time?

I want to fix this because it is annoying that users needs to click retry.

Does someone got a solution for this?

Answer: In Android 4.4 they work with OkHttpclient so thats the reason why it is working on 4.4 and not on the older Android versions.

To solve this add a dependency in gradle:

compile 'com.squareup.okhttp:okhttp-tests:1.5.1'

and create a new client like this:

OkHttpClient client = new OkHttpClient();

add that new client to the restadapter to use this:

setClient(new OkClient(client))

The error should be solved now.

bug retrofit.RetrofitError: for Android

Question: I search a lot, I found some solutions like this:

System.setProperty("http.keepAlive", "false");
arg0.addHeader("Connection", "close");
arg0.addHeader("Accept-Language", "en-US,en;q=0.8");

I try them but didn't work for me. How can I correct this bug? Here is my log:

D/Retrofit(28969): ---> 
D/Retrofit(28969): Connection: close
D/Retrofit(28969): Content-Type: application/json
D/Retrofit(28969): Content-Length: 169

Answer: the solution was to use both OkClient and OkHttp. After adding these two libraries I set the client on Retrofit to OkHttp like that:

RestAdapter restAdapter = new RestAdapter.Builder()
    .setErrorHandler(new ErrorRetrofitHandlerException())
    .setClient(new OkClient(new OkHttpClient()))
