Retrofit: Retrofit not call in android pie

[techhuntdevelopers]

What kind of issue is this?

• [ ] Bug report. If you’ve found a bug, spend the time to write a failing test. Bugs with tests
  get fixed. Here’s an example:

`Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ApiInterface.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();

    ApiInterface api = retrofit.create(ApiInterface.class);

    Call<ResultModel> call = api.getFileSource(position);
    call.enqueue(new Callback<ResultModel>() {
        @Override
        public void onResponse(Call<ResultModel> call, Response<ResultModel> response) {

            examples = new ArrayList<>();
            examples = response.body().getFileSourceList();

            DownloadFileTask downloadFileTask = new DownloadFileTask(examples);
            downloadFileTask.execute();

            if (pd.isShowing()) {
                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    public void run() {
                        pd.dismiss();
                    }
                }, 5000);
            }
        }

        @Override
        public void onFailure(Call<ResultModel> call, Throwable t) {
            if (pd.isShowing()) {
                pd.dismiss();
            }
        }
    });`

Not enough information to reproduce. We're using Pie. Can you isolate into a standalone test case?

i m also face this problem.any solution?

[JakeWharton]

Android 9.0 disables cleartext traffic by default: https://developer.android.com/about/versions/pie/android-9.0-changes-28#framework-security-changes. Use HTTPS or explicitly enable unsafe HTTP calls.

[techhuntdevelopers]

Just add this line in AndroidManifest.xml

android:usesCleartextTraffic="true"

[maheshsystimanx]

android:usesCleartextTraffic="true"

thank you .This code is working

Hii @JakeWharton
Server Timeout Issue :
In Android when I am using the Retofit Api. Server response is getting delay for more than five minutes due to Server slow down.On that time how can I show the message to the user.
