安卓設備日曆上未顯示的事件

Question

我們正在研究android應用程序，我們正試圖在後臺服務中默默添加事件。使用以下代碼是相同的：

package com.red_folder.phonegap.plugin.backgroundservice.sample; 

import java.text.SimpleDateFormat; 
import java.util.Calendar; 
import java.util.Date; 
import java.util.TimeZone; 


import org.json.JSONException; 
import org.json.JSONObject; 
import org.json.JSONArray; 

import android.annotation.SuppressLint; 
import android.content.ContentResolver; 
import android.content.ContentValues; 
import android.content.Context; 
import android.content.Intent; 
import android.content.ContentUris; 
import android.net.Uri; 
import android.os.Bundle; 
import android.provider.CalendarContract; 
import android.provider.CalendarContract.Events; 
import android.provider.CalendarContract.Reminders; 
import android.util.Log; 

import org.apache.cordova.CallbackContext; 
import org.apache.cordova.CordovaPlugin; 
import org.apache.cordova.PluginResult; 

import com.red_folder.phonegap.plugin.backgroundservice.BackgroundService; 


@SuppressWarnings("deprecation") 
public class MyService extends BackgroundService { 

    private final static String TAG = MyService.class.getSimpleName(); 

    private String mHelloTo = "World"; 

    @SuppressLint("NewApi") 
    @SuppressWarnings("static-access") 
    @Override 
    protected JSONObject doWork() { 
     JSONObject result = new JSONObject(); 



      Log.d(TAG, "Start calendar insertion"); 

      JSONObject jsonArray; 

      long calID = 3; 
      long startMillis = 0; 
      long endMillis = 0;  
      Calendar beginTime = Calendar.getInstance(); 
      beginTime.set(2014, 9, 14, 7, 30); 
      startMillis = beginTime.getTimeInMillis(); 
      Calendar endTime = Calendar.getInstance(); 
      endTime.set(2014, 9, 14, 8, 45); 
      endMillis = endTime.getTimeInMillis(); 


      ContentResolver cr = getContentResolver(); 
      ContentValues values = new ContentValues(); 
      values.put(Events.DTSTART, startMillis); 
      values.put(Events.DTEND, endMillis); 
      values.put(Events.TITLE, "Jazzercise"); 
      values.put(Events.DESCRIPTION, "Group workout"); 
      values.put(Events.CALENDAR_ID, calID); 
      values.put(Events.VISIBLE, 0); 
      values.put(Events.EVENT_TIMEZONE, "America/Los_Angeles"); 
      Uri uri = cr.insert(Events.CONTENT_URI, values); 

      // get the event ID that is the last element in the Uri 
      long eventID = Long.parseLong(uri.getLastPathSegment()); 




      Log.d(TAG, "End calendar insertion"); 


     return result; 
    } 

    @Override 
    protected JSONObject getConfig() { 
     JSONObject result = new JSONObject(); 

     try { 
      result.put("HelloTo", this.mHelloTo); 
     } catch (JSONException e) { 
     } 

     return result; 
    } 

    @Override 
    protected void setConfig(JSONObject config) { 
     try { 
      if (config.has("HelloTo")) 
       this.mHelloTo = config.getString("HelloTo"); 
     } catch (JSONException e) { 
     } 

    }  

    @Override 
    protected JSONObject initialiseLatestResult() { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    protected void onTimerEnabled() { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    protected void onTimerDisabled() { 
     // TODO Auto-generated method stub 

    } 


} 

該代碼被返回一個EVENTID這意味着它被添加到事件日曆裝置，但沒有事件被顯示在日曆。 我們可以做什麼來顯示設備日曆上添加的事件？

這裏是我的代碼（包括最後的「強制同步」）在日曆中打開和寫入。也許你可以在那裏找到你的答案，它的工作完美無瑕。
