在Android 4.4.2中,单击我的Foreground Service通知会终止我的进程.

在较旧的设备上(Samsuing Tab 2运行4.2.2),我可以从最近的任务中删除活动,并且仍然可以在后台运行我的服务.然后,当我点击通知时,我的应用程序活动再次开心.

但是,一旦我点击运行4.4.2的Nexus 7上的通知,我的进程就会被终止(直到点击在后台运行得很快). PendingIntent似乎根本没有触发,或者至少它没有触及BroadcastReceiver的第一行：

05-21 16:17:38.939: I/ActivityManager(522): Killing 2268:com.test.student/u0a242 (adj 0): remove task

我已经通过this回答,并使用命令dumpsys activity proccesses我已经确认我的服务正在前台正确运行.

那么,点击这个杀死我的进程的通知又是什么呢？

将服务移至前台所涉及的代码如下：

服务：

@Override
public int onStartCommand(Intent intent,int flags,int startId) {
    Log.i("NativeWrappingService","Starting Service...");
    startForeground(NotificationIcon.NOTIFICATION_STUDENT,NotificationManager.getStudentIcon(this).getNotification());    
    return super.onStartCommand(intent,flags,startId);
}

NotificationIcon：(getStudentIcon(this).getNotification())

public Notification getNotification() {
    Builder mBuilder = new Builder(mContext);

    if(mSmallIcon   != -1)      mBuilder.setSmallIcon(mSmallIcon);
    if(mLargeIcon   != null)    mBuilder.setLargeIcon(mLargeIcon);
    if(mTitle       != null)    mBuilder.setContentTitle(mTitle);
    if(mSubTitle    != null)    mBuilder.setContentText(mSubTitle);
    if(mSubTitleExtra != null)  mBuilder.setContentInfo(mSubTitleExtra);

    mBuilder.setOngoing(mOngoing);
    mBuilder.setAutoCancel(mAutoCancel);
    mBuilder.setContentIntent(getPendingIntent(mContext,mAction,mBundle,mActivity));

    return mBuilder.build();
}

private PendingIntent getPendingIntent(Context context,String action,Bundle extras,String activity) {
    Intent newIntent = new Intent(context,BroadcastToOrderedBroadcast.class);
    Bundle bundle;
    if(extras != null)  bundle = extras;
    else                bundle = new Bundle();

    if(activity != null && !activity.equalsIgnoreCase("")) {
        BundleUtils.addActivityToBundle(bundle,activity);
    }

    BundleUtils.addActionToBundle(bundle,action);

    newIntent.putExtras(bundle);

    return PendingIntent.getBroadcast(NativeService.getInstance(),mNotificationID,newIntent,PendingIntent.FLAG_UPDATE_CURRENT);
}
