here is a json code in java file:

     } else {

     }
}

Other codes:

private final OkHttpClient client = new OkHttpClient();


Call post(String url, RequestBody formBody, Callback callback) throws IOException {

    Request request = new Request.Builder()
            .url(url)
            .post(formBody)
            .build();

    client.setConnectTimeout(30, TimeUnit.SECONDS);
    client.setReadTimeout(30, TimeUnit.SECONDS);
    client.setWriteTimeout(30, TimeUnit.SECONDS);

    Call call = client.newCall(request);
    call.enqueue(callback);
    return call;
}

IOExceptiojava.net.SocketTimeoutException is occurring on following condition.

  1. Server is slow and default timeout is less. so just put timeout value according to you.
  2. Server is working fine but timeout value is for less time. so change the timeout value. like below code snippet.

OkHttpClient client = new OkHttpClient();

client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);

If you are using okhttp3 then you must do it using the builder.

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(30, TimeUnit.SECONDS); 
builder.readTimeout(30, TimeUnit.SECONDS); 
builder.writeTimeout(30, TimeUnit.SECONDS); 
client = builder.build();
