回答1:

I also had the same issue. The issue was I am using socket 0.8.0 which I think has conflict with OKHTTP websocket implem.

Upon upgrading to the latest version of socket.io

compile('io.socket:socket.io-client:0.8.3') {
    exclude group: 'org.json', module: 'json'
}

and also using the latest version of OKHTTP (no need to include okhttp-ws)

compile "com.squareup.okhttp3:okhttp:3.7.0"
compile "com.squareup.okhttp3:logging-interceptor:3.7.0"

my app is not crashing upon first load and it is connecting to sockets. Interceptor also has no conflict whatsoever and is logging as expected on logcat.

With this, there is no need to downgrade your version of okHTTP for which it has been the working solution in the past. :)

回答2:

Hi there，I have the same issue just days ago(my app is a react-native) ,I just use the 3.4.1 version to replace the latest，and solved it！

compile "com.squareup.okhttp3:okhttp:3.4.1"
compile "com.squareup.okhttp3:logging-interceptor:3.4.1"

and I guess it is caused by the Retrofit2's okhttp lib

回答3:

I had this issue after launching the Android Studio Profiler, even after closing the profiler. Had to restart Android Studio to fix it.

回答4:

I had similar issue. Problem with my project was it was using okhttp-3.3.1 which do not have method setCallWebSocket.

Make sure you add correct version of okhttp in your gradle and the older version which does not have setCallWebSocket are not included elsewhere under your project libraries or dependencies.
