android - 错误 : Failed to find provider info for com. android.calendar

Question

我正在开发一个提醒应用程序。我在日历中设置提醒。我在 eclipse 上试过的代码如下所示:

public class MainActivity extends Activity {

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    addReminder();
}

public void addReminder(){
    String eventUriString = "content://com.android.calendar/events";
    ContentResolver cr = getContentResolver();
    ContentValues eventValues = new ContentValues();

    eventValues.put(Events.CALENDAR_ID, 1);
    eventValues.put(Events.TITLE, "Hello");
    eventValues.put(Events.DESCRIPTION, "Hello Android");
    eventValues.put(Events.EVENT_TIMEZONE, "India");

    Calendar beginTime = Calendar.getInstance();
    beginTime.set(2013, 01, 01, 18, 05);
    long startMillis = beginTime.getTimeInMillis();

    Calendar endTime = Calendar.getInstance();
    endTime.set(2013, 01, 01, 18, 06);
    long endMillis = endTime.getTimeInMillis();

    eventValues.put(Events.DTSTART, startMillis);
    eventValues.put(Events.DTEND, endMillis);
    eventValues.put("eventStatus", 1);
    eventValues.put("visibility", 3); 
    eventValues.put("transparency", 0); 
    eventValues.put("hasAlarm", 1); 
    Uri eventUri = getContentResolver().insert(Uri.parse(eventUriString), eventValues);
    long eventID = Long.parseLong(eventUri.getLastPathSegment());      

    String reminderUriString = "content://com.android.calendar/reminders";
        ContentValues reminderValues = new ContentValues();

        reminderValues.put("event_id", eventID);
        reminderValues.put("minutes", 5); 
        reminderValues.put("method", 1);
    Uri reminderUri = this.getApplicationContext().getContentResolver().insert(Uri.parse(reminderUriString), reminderValues);
    }
}

哪里出现错误:

这是我在运行我的应用程序时收到的错误日志。我还提供了日历中的读取和赖特权限。

我应该遵循什么步骤或者我应该做什么或更改以避免错误。我在我的模拟器上运行这段代码。

谢谢。

Answer 1

当我在模拟器上运行我的应用程序时，该错误发生在我的应用程序中。因为在我的模拟器中没有可供访问的日历。
