使用来自BroadcastReceiver Android的警报添加日历事件

Question

我需要在收到推送通知时以编程方式设置日历事件。我的BroadcastReceiver中已经有了所有推送通知代码，但是当我尝试使用ContentResolver添加日历事件时，我的应用程序崩溃了。

我得到的错误是： java.lang.RuntimeException：无法启动接收器m.example.com.rm.CustomHandler：java.lang.SecurityException：Permission Denial：从ProcessRecord打开提供程序com.android.providers.calendar.CalendarProvider2 {e60c308 30235：m .example.com.rm / u0a63}（pid = 30235，uid = 10063）要求

android.permission.READ_CALENDAR 

android.permission.WRITE_CALENDAR

（我有added两个必要permissions）

这是我的代码：

       public class CustomHandler extends BroadcastReceiver
       {

            public void onReceive(Context context, Intent intent)
            {
                    long startMillis = 0 ;
                    long endMillis = 0;

                    Calendar beginTime = Calendar.getInstance() ;
                    beginTime.setTime(s.getDate()) ;
                    startMillis = beginTime.getTimeInMillis() ;

                    Calendar endTime = Calendar.getInstance();
                    Date endDate = s.getDate() ;
                    endDate.setMinutes(endDate.getMinutes() + 5) ;
                    endTime.setTime(endDate);
                    endMillis = endTime.getTimeInMillis();


                    long calID = 3;
                    ContentResolver cr = c.getContentResolver();
                    ContentValues values = new ContentValues();
                    values.put(Events.DTSTART, startMillis);
                    values.put(Events.DTEND, endMillis);
                    values.put(Events.TITLE, "BP Reading");
                    values.put(Events.DESCRIPTION, "Please open the RMCuff App to take your scheduled reading :)");

                    values.put(Events.CALENDAR_ID, calID);

                    values.put(Events.EVENT_TIMEZONE, "America/New_York");
                    values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
                    Uri uri = cr.insert(Events.CONTENT_URI, values);
                    }
            }
