为什么我不能创建日历？

Question

我在我的 SignActivity 中使用了 Google SignIn，如下所示：

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.server_client_id))
            .requestEmail()
            .requestProfile()
            .build();
// [END configure_signin]

// [START build_client]
// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
// [END build_client]

SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
signInButton.setSize(SignInButton.SIZE_WIDE);
signInButton.setScopes(gso.getScopeArray());

现在我可以获取token、邮箱名和其他信息了。

然后我按照 this example 在我的另一个 activity 中为给定的电子邮件创建了一个日历，如下所示：

//for calendar start
static final int REQUEST_ACCOUNT_PICKER = 1000;
static final int REQUEST_AUTHORIZATION = 1001;
static final int REQUEST_GOOGLE_PLAY_SERVICES = 1002;
private static final String PREF_ACCOUNT_NAME = "accountName";
private static final String[] SCOPES = { CalendarScopes.CALENDAR };
GoogleAccountCredential mCredential;
com.google.api.services.calendar.model.Calendar calendar;
//for calendar end

 @Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    createBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // I take the email from my sign activity.
            String emailName = SignActivity.getPref(PREF_ACCOUNT_NAME, getApplicationContext());
            mCredential = GoogleAccountCredential.usingOAuth2(
                    getApplicationContext(), Arrays.asList(SCOPES))
                    .setBackOff(new ExponentialBackOff())
                    .setSelectedAccountName(emailName);
            if (isDeviceOnline()) {
                new MakeRequestTask(mCredential).execute();
            } else {
                descriptionEditText.setText("No network connection available.");
            }
        }
    });
    ...
}

和我的 MakeRequestTask 构造函数：

HttpTransport transport = AndroidHttp.newCompatibleTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
mService = new Calendar.Builder(
         transport, jsonFactory, credential)
         .setApplicationName("Test")
         .build();

而且我的问题出在 try 块第一行的 doInBackground 函数中，它无法执行和执行其他代码，但奇怪的是我没有收到任何错误：

try{
    com.google.api.services.calendar.model.Calendar createdCalendar = mService.calendars().insert(calendar).execute();

    CalendarListEntry calendarListEntry = new CalendarListEntry();
    calendarListEntry.setId(createdCalendar.getId());
    calendarListEntry.setBackgroundColor(backGroundColor);
    calendarListEntry.setForegroundColor(foreGroundColor);
    // Insert the new calendar list entry
    CalendarListEntry createdCalendarListEntry = mService.calendarList().insert(calendarListEntry).execute();
        Log.i("summary", createdCalendarListEntry.getSummary());
    }catch (IOException e){
            Log.i("test1", e.getMessage());
    }

Answer 1

在我的 createBtn onClick 函数中

我在其他代码的顶部添加了以下代码：

I'm not sure this is the real solution. But in my old codes there were no ask for permission for calendar but now it is asking me to give a permission.

if (mCredential.getSelectedAccountName() == null) {
    chooseAccount();
}

现在可以使用了。
