GmailApi получать сообщения на Android

1 голос
/ 28 мая 2020

Я пытаюсь получить все сообщения из Gmail с помощью GmailApi. Но когда я запускаю код, появляется эта ошибка.

"java .lang.RuntimeException: невозможно запустить действие ComponentInfo {com. yousefelsayed.myemail / com.yousefelsayed.myemail.MainActivity}: java .lang.IllegalArgumentException: имя не должно быть пустым: null"

И это говорит мне, что ошибка из этой строки 

ListThreadsResponse listResponse = mService.users().threads().list("me").execute();

В чем проблема

MyCode: 

mCredential = GoogleAccountCredential.usingOAuth2(
            getApplicationContext(), SCOPES)
            .setBackOff(new ExponentialBackOff());

    HttpTransport transport = AndroidHttp.newCompatibleTransport();

    JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
    mService = new com.google.api.services.gmail.Gmail.Builder(
            transport, jsonFactory, mCredential)
            .setApplicationName(getResources().getString(R.string.app_name))
            .build();
try {
            ListThreadsResponse listResponse = mService.users().threads().list("me").execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
