okhttp 3 very slow

Question

I try to get json from a server, I use https on the server and every http request will go to the https version.

I get the data ~~and the data that I send works to~~ but it takes up to 45 sec to get a response back. The same code was faster with the build in http handler of android.

How can I speed up the request?

try {
        OkHttpClient client = new OkHttpClient();
        FormBody.Builder formBuilder = new FormBody.Builder().add("key", "2285");
        //formBuilder.add("phone", "000000");

        RequestBody formBody = formBuilder.build();
        Log.v("JsonRespons", reqUrl);
        Request request = new Request.Builder()
                .url(reqUrl)
                .post(formBody)
                .build();

        okhttp3.Response response = null;

        response = client.newCall(request).execute();

        if (!response.isSuccessful()) {
            throw new IOException(response.message() + " " + response.toString());
        } else {
            output = response.body().string();
        }

        if(output != null) {
            Log.v("JsonRespons", output.toString());
        }
    } catch (IOException e) {
         e.printStackTrace();
    }

What Thread are you executing on? If you don't know much about threads just go for the async as its done in the following answer. https://stackoverflow.com/questions/34967505/android-okhttp-asynchronous-calls — loshkin, Nov 14 '17 at 14:55
@toshkinl - i have build a class for getting json from a url, this part of the code is from that class — allegs34, Nov 14 '17 at 15:09

You must consider some important things :

Executing Okhttp3 request away from UI thread, like AsyncTask.

Don't forget to close response body after complete.

    new AsyncTask<String,Void,String>(){

    @Override
    protected String doInBackground(String... strings) {
        String strResponse = null;
        try {
            Response response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                strResponse = response.body().string();
                response.close();  // DON't forget to close body =@response.body().close();
            }

        }catch (Exception ex){
        }
        return strResponse;
    }

    @Override
    protected void onPostExecute(String s) {
        // Update UI here
    }
};

Using okhttp3 thread using enqueue

client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        // When failure 
        mActivity.runOnUiThread(); // If need to update UI
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        if (response.isSuccessful()){
            String result = response.body().string();
            mActivity.runOnUiThread(); // update UI under UI thread.
            response.close();  // close response body.
        }
    }
});

Creating OkHttp3Client and configure timeout.

private static OkHttpClient createHttpclient() {
final OkHttpClient.Builder builder =  new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS);
setSocketFactory(builder); // To handle SSL certificate. 
return builder.build();
}
