AlarmManager的意圖故障

嘿，所以我一直在製作一個應用程序，它在用戶指定的時間發送每週通知。AlarmManager的意圖故障

我遵循了大量的教程，似乎一遍又一遍地讀了同樣的東西，我似乎無法讓它工作。當我調用新的意圖時，我的應用程序崩潰。難道我做錯了什麼？這是完成這項任務的正確方法嗎？

public class AlarmService extends Activity 
{ 

    /// unimportant working code not added 

    Intent mintent = new Intent(context, mBroadcastReceiver.class); 
    Log.d(TAG, "Got Intent"); 
    /// I receive a log just before this portion but do not receive this one 

    startActivity(PAintent); 
    Log.d(TAG, "StartActivity(intent)"); 

    PendingIntent mPendingIntent = PendingIntent.getActivity(getApplicationContext(), ALARMID, 
     mintent, PendingIntent.FLAG_CANCEL_CURRENT); 
    Log.d(TAG, "Got Pending intent"); 

    AlarmManager mAlarm = (AlarmManager) getSystemService(ALARM_SERVICE); 
    Log.d(TAG, "Got alarmmanager"); 

    ///// remember to change time back to: (7 * 24 * 60 * 60 * 1000) 
    mAlarm.setRepeating(AlarmManager.RTC_WAKEUP, 
    ALARM_TIME.getTimeInMillis(), (30 * 1000), 
    mPendingIntent); 
    Log.d(TAG, "Made Pending intent"); 
    ... 
}

請記住，我在本代碼中更改了我的意圖，pendingintent和鬧鐘管理器，以便於閱讀！

我不斷收到一個空指針異常，我的調試是這樣的：

03-05 13:20:45.132: E/AndroidRuntime(12734): FATAL EXCEPTION: main 
03-05 13:20:45.132: E/AndroidRuntime(12734): java.lang.NullPointerException

03-05 13:20:45.132: E/AndroidRuntime(12734): at android.view.View.performClick(View.java:2485)

...等等

如果有人能指出我的錯誤，將不勝感激！

startActivity（PAintent）; PAintent在哪裏？你創造它嗎？

要啓動日程安排的活動：你可以看到這個鏈接： Android : AlarmManager not start
