java.lang.NoClassDefFoundError: org.phoenixframework.channels.Socket$PhoenixWSListener

I don't if this is really an issue with the library or a mistake on my end so I post here anyway.

This is my build configuration:

apply plugin: 'com.android.application'

android {

    buildToolsVersion "25.0.3"
    defaultConfig {

    }

        }
    }
}

I get the following error as soon as any socket methods are invoked:

java.lang.NoClassDefFoundError: org.phoenixframework.channels.Socket$PhoenixWSListener E at org.phoenixframework.channels.Socket.<init>(Socket.java:167) E at org.phoenixframework.channels.Socket.<init>(Socket.java:170) E at com.sandzar.paywand.sockets.SocketService.initiateSocketConnection(SocketService.java:66) E at com.sandzar.paywand.sockets.SocketService.onStartCommand(SocketService.java:50) E at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:3010) E at android.app.ActivityThread.access$2200(ActivityThread.java:150) E at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1442) E at android.os.Handler.dispatchMessage(Handler.java:102) E at android.os.Looper.loop(Looper.java:148) E at android.app.ActivityThread.main(ActivityThread.java:5417) E at java.lang.reflect.Method.invoke(Native Method) E at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:764) E at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) Process I Sending signal.

The is the portion of code that causes the error:

private void initiateSocketConnection() {
    try {
        Log.e(DEBUG_TAG, "initiateSocketConnection") ;
        socket = new Socket(Constants.CHANNEL_URL);
        socket.onOpen(new ISocketOpenCallback() {
            @Override
            public void onOpen() {
                try {
                    final ObjectNode payload = objectMapper.createObjectNode();
                    payload.put("token", UserRepository.getInstance().getLoggedInUser().getAuthenticationToken()) ;
                    channel = socket.chan(getUserChannelTopic(), payload);
                    channel.join().receive("ok", new IMessageCallback() {
                        @Override
                        public void onMessage(final Envelope envelope) {
                            Log.e(DEBUG_TAG, "Joined channel successfully") ;
                        }
                    });
                    channel.on("payment:new", new IMessageCallback() {
                        @Override
                        public void onMessage(Envelope envelope) {

                        }
                    }) ;
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });
        socket.onClose(new ISocketCloseCallback() {
            @Override
            public void onClose() {

            }
        });
        socket.onError(new IErrorCallback() {
            @Override
            public void onError(String s) {

            }
        });
    } catch(Exception e) {
        e.printStackTrace() ;
    }
}

Here is some extra output from the console:

This issue appeared because of different versions of okhttp.
Retrofit has 3.8.1, but phoenix has 3.6.0
There are two ways to solve this problem right now:

• Downgrade version of retrofit
• Fork phoenix and update version of okhttp

Hello
i had facing same warning
W/Java7Support: Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

Tried solution
--->I have updated java 1.7 to 1.8 in ubuntu os

--->changed java version in app level gradle
compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

and Fork phoenix and update version of okhttp3 from 3.6.0 to 3.10.0

but still getting this warning and i am not able to do socket connection
It would be helpful to me if any one had faced same issue and help to solve this issue

Thanks in advance
