Android的通知重新启动应用程序，但想要恢复 [英] Android Notification restarts app but want to resume

问题描述

您好我有一个能够得到显示我的活动通知，并在用户     点击通知应用程序重新启动。不过，我只是希望它重新出现无法重新启动。例如。它是一个Web应用程序，我想它来前，当用户选择了notification..but不刷新网页。我可以捕获该意图还是我发送了错误的意图是什么？通常情况下，如果我preSS主页按钮，然后点击应用程序图标，应用程序就浮出水面，并且不刷新/重新启动。所以，这就是我想要的行为。任何想法？

 字符串NS = Context.NOTIFICATION_SERVICE;
 NotificationManager mNotificationManager =（NotificationManager）
                                             getSystemService（纳秒）;
 //2.Instantiate通知
 INT图标= R.drawable.notification_icon;
 CharSequence的tickerText =我的应用;在状态行//临时味精
 时长= System.currentTimeMillis的（）;
 通知通知=新的通知（图标，tickerText时）;
 notification.flags | = Notification.FLAG_ONGOING_EVENT;
 //3.Define通知扩大的消息，意图：
 上下文的背景下= getApplicationContext（）;
 CharSequence的contentTitle =通知;
 CharSequence的contentText =我的应用程序！ //消息给用户
 意图notificationIntent =新的意图（这一点，HelloAndroid2.class）;
 PendingIntent contentIntent = PendingIntent.getActivity（此，0，
                                                          notificationIntent，0）;
 notification.setLatestEventInfo（背景下，contentTitle，contentText，
                                                          contentIntent）;
 //4.Pass通知到NotificationManager：
 最终诠释NOTIFICATION_ICON_ID = 1;
 mNotificationManager.notify（NOTIFICATION_ICON_ID，通知）;
 

解决方案

我在清单把这个

 安卓launchMode =singleInstance
 

这解决了这个问题对我来说。此外这个答案我还没有尝试过这暗示其他感兴趣的东西。

Hi I have a been able to get a notification displayed for my activity, and when the user clicks the notification the app restarts. However I just want it to reappear not restart. eg. it is a web app and I want it to come to the front when the user selects the notification..but not refresh the web page. Can I trap this intent or am I sending the wrong intent? Normally if I press the home button and click on the app icon the app comes to the fore and doesn't refresh/restart. So this is the behaviour I want. Any ideas ?

 String ns = Context.NOTIFICATION_SERVICE;
 NotificationManager mNotificationManager = (NotificationManager)
                                             getSystemService(ns);
 //2.Instantiate the Notification
 int icon = R.drawable.notification_icon;
 CharSequence tickerText = "My App";  // temp msg on status line 
 long when = System.currentTimeMillis();
 Notification notification = new Notification(icon, tickerText, when);
 notification.flags |= Notification.FLAG_ONGOING_EVENT;
 //3.Define the Notification's expanded message and Intent: 
 Context context = getApplicationContext();
 CharSequence contentTitle = "Notification";
 CharSequence contentText = "My app!"; // message to user
 Intent notificationIntent = new Intent(this, HelloAndroid2.class);
 PendingIntent contentIntent = PendingIntent.getActivity(this, 0, 
                                                          notificationIntent, 0);
 notification.setLatestEventInfo(context, contentTitle, contentText,
                                                          contentIntent);
 //4.Pass the Notification to the NotificationManager:  
 final int NOTIFICATION_ICON_ID = 1;
 mNotificationManager.notify(NOTIFICATION_ICON_ID, notification);

解决方案

I put this in manifest

android:launchMode="singleInstance"

This fixed the problem for me. Also this answer which I have not tried which allude to other things of interest.
