我有一个应用程序，其中警报需要对存储在数据库中的时间值进行播放。当我删除语句“notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE;”时，会在该警报时间出现通知没有播放闹钟。当我插入上面的语句时，警报会通过强行压缩我的应用程序来播放。我的警报类如下：
public class AlarmManager extends BroadcastReceiver {
sampleDatabase appdb;
SQLiteDatabase sqldb;
Cursor cursor;
int today,prev;
Intent in;
@Override
public void onReceive(Context context, Intent intent)
{
NotificationManager manger = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon , "Yahrzeit" , System.currentTimeMillis());
in = new Intent(context,FirstAppActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, in, 0);
notification.setLatestEventInfo(context, "ALERT!!!!", "Time Over" , contentIntent);
notification.defaults=Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE;
notification.flags = Notification.FLAG_INSISTENT;
appdb = new sampleDatabase(context);
sqldb = appdb.getReadableDatabase();
cursor = sqldb.query(sampleDatabase.TABLE_SEC, null, null, null, null, null, null);
cursor.moveToFirst();
Calendar cal = Calendar.getInstance();
cal.set(Calendar.SECOND, 0);
today = (int)(cal.getTimeInMillis()/1000);
Log.e("Naga","Alarm");
Log.e("today",Integer.toString(today));
prev = 0;
cursor.moveToPrevious();
while(cursor.moveToNext())
{
int dbdate = cursor.getInt(cursor.getColumnIndex(sampleDatabase.ALARMSET));
int id = cursor.getInt(cursor.getColumnIndex(sampleDatabase.ROW_ID));
Log.e("dbdate",Integer.toString(dbdate));
if((dbdate<=today)&&(dbdate>prev))
{
manger.cancelAll();
manger.notify(1, notification);
sqldb.execSQL("DELETE from " + sampleDatabase.TABLE + " where " + sampleDatabase.ROW_ID + "=" + id);
sqldb.execSQL("DELETE from "+sampleDatabase.TABLE_SEC + " where " + sampleDatabase.ROW_ID + "=" + id);
}
prev = dbdate;
}
cursor.close();
sqldb.close();
}
我的logcat视图是这样的（我已经插入了vibrate的权限，然后也出现了这个错误。）：

请帮助我。 我的清单是：
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".FirstAppActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".addtable"
android:label="@string/app_name">
</activity>
<activity android:name=".showTime"
android:label="@string/app_name">

Caused by: java.lang.SecurityException: Requires VIBRATE permission
向清单添加VIBRATE权限。
<uses-permission android:name="android.permission.VIBRATE" />
您已将此标记放在应用标记中。它应该在应用程序标记之外。像这样：
