Question

我正在尝试使用以下代码将事件插入日历：

package come.jobfinder.dev;

import java.util.Calendar;

import org.junit.Test;

import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Intent;
import android.net.Uri;
import android.provider.CalendarContract;
import android.provider.CalendarContract.Events;

public class CalendarWrapper extends Activity {

    public void syncDataWithCalendar(String workPlace , Calendar date){

        //TODO should be a field that user should fill - intreviewLength
        int intreviewLength = 60;// set it default to be an hour , will be a field user should fill
        //TODO should be a field that will be sent - position
        String position = "Product Manager";
        //TODO  should be a field that will be sent - location
        String location = "Tel Aviv";
        //TODO need to check where to take this argument from
        long calID = 3;
        Calendar beginTime = Calendar.getInstance();
        beginTime.set(date.get(Calendar.YEAR), date.get(Calendar.MONTH), date.get(Calendar.DAY_OF_MONTH), date.get(Calendar.HOUR), date.get(Calendar.MINUTE));
        Calendar endTime = Calendar.getInstance();
        endTime.set(date.get(Calendar.YEAR), date.get(Calendar.MONTH), date.get(Calendar.DAY_OF_MONTH), date.get(Calendar.HOUR), date.get(Calendar.MINUTE)+intreviewLength);
        Intent intent = new Intent(Intent.ACTION_INSERT)
                .setData(Events.CONTENT_URI)
                .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, beginTime.getTimeInMillis())
                .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, endTime.getTimeInMillis())
                .putExtra(Events.TITLE, "Job Interview with "+workPlace)
                .putExtra(Events.DESCRIPTION, "Job interview with "+workPlace+" for the position"+position)
                .putExtra(Events.EVENT_LOCATION, location)
                .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
                .putExtra(Intent.EXTRA_EMAIL, "rowan@example.com,trevor@example.com");

        startActivity(intent);

        //return intent;

        // get the event ID that is the last element in the Uri
    }
}

并收到以下错误：

很难说出发生了什么。你在跟踪中得到一个空指针异常，哪个源语句失败了？

无法将事件插入到Android日历中
