java - Android 开机接收器崩溃

Question

我的手机已连接到 Eclipse，但我无法看到 logcat，直到手机“完全”启动并且我的接收器(应用程序)在此之前崩溃，所以我无法调试它。我确定它必须根据上下文和 Intent 做一些事情:

我确定由于上下文问题，我的接收器在启动时崩溃了:

 public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Calendar c2 = Calendar.getInstance();               
    int hour = c2.get(Calendar.HOUR_OF_DAY);
    int minute = c2.get(Calendar.MINUTE);
    int sek = c2.get(Calendar.SECOND);

    int dan;
    int dodaj;

    milivreme = ((hour * 60 * 60 * 1000)+ (minute * 60 * 1000) + (sek * 1000));

    Cursor cursor = DatabaseManager.getAllData();

    cursor.moveToFirst();
    if (!cursor.isAfterLast())
    {
        do
        {               
    milibaza = cursor.getInt(3);
    razlika = milibaza - milivreme;

    Intent intent1 = new Intent(context, AlarmReceiver.class);
    PendingIntent pendingintent = PendingIntent.getService(context, 2, intent1, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);

    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + razlika, pendingintent);
        }
        while (cursor.moveToNext());
    }
}   

更新，终于成功捕捉到异常:

01-06 02:21:19.920: E/AndroidRuntime(7360): java.lang.RuntimeException: Unable to start receiver com.example.prva.OnBootReceiver: java.lang.NullPointerException

你应该只使用上下文，用上下文替换上下文，你应该没问题。
