Android - 当我的应用完成后恢复后台应用

Question

基本上，我正在浏览互联网或查看其他应用。我收到一条通知，打开我的应用程序。我做了一些东西，它完成。我的应用程序关闭，我回到了启动器。我如何让我的应用程序完成并将我返回到之前浏览过的任何应用程序/ Chrome页面？

AndroidManifest节这个活动：

<activity 
     android:name=".AcceptRejectActivity" 
     android:label="@string/title_activity_accept_reject" 
     android:screenOrientation="portrait" > 
    </activity> 

通知码：

mNotificationManager = (NotificationManager) 
      this.getSystemService(Context.NOTIFICATION_SERVICE); 
    Intent resultIntent = new Intent(this, AcceptRejectActivity.class); 
    resultIntent.putExtra("message","Do you choose to accept this message?");  

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); 
    stackBuilder.addParentStack(AcceptRejectActivity.class); 

    // Adds the Intent that starts the Activity to the top of the stack // 
    stackBuilder.addNextIntent(resultIntent); 
    PendingIntent contentIntent = 
      stackBuilder.getPendingIntent(
        0, 
        PendingIntent.FLAG_UPDATE_CURRENT 
      ); 
    String msg = "You have a message" 
    NotificationCompat.Builder mBuilder = 
      new NotificationCompat.Builder(this) 
        .setSmallIcon(R.drawable.ic_logo) 
        .setContentTitle("Message") 
        .setStyle(new NotificationCompat.BigTextStyle() 
          .bigText(msg)) 
        .setContentText(msg) 
        .setPriority(Notification.PRIORITY_HIGH); 
    mBuilder.setContentIntent(contentIntent); 
    mBuilder.setAutoCancel(true); 

    android.app.Notification note = mBuilder.build(); 
    note.defaults |= android.app.Notification.DEFAULT_VIBRATE; 
    note.defaults |= android.app.Notification.DEFAULT_SOUND;   

    mNotificationManager.notify(0, note); 

片段的关闭功能

private void allDone() { 
     Log.i(TAG, "The choice has been made");    
     getActivity().finish(); 
     //NavUtils.navigateUpFromSameTask(getActivity()); 
    }

我设法解决了我的问题。

Android清单：

<activity 
     android:name=".AcceptRejectActivity" 
     android:label="@string/title_activity_accept_reject" 
     android:screenOrientation="portrait" 
     android:launchMode="singleInstance" 
     android:excludeFromRecents="true"> 
    </activity> 

通知码： 改变了的PendingIntent是如何产生的。

mNotificationManager = (NotificationManager) 
     this.getSystemService(Context.NOTIFICATION_SERVICE); 
Intent resultIntent = new Intent(this, AcceptRejectActivity.class); 
resultIntent.putExtra("message","Do you choose to accept this message?");  

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

String msg = "You have a message" 
NotificationCompat.Builder mBuilder = 
     new NotificationCompat.Builder(this) 
       .setSmallIcon(R.drawable.ic_logo) 
       .setContentTitle("Message") 
       .setStyle(new NotificationCompat.BigTextStyle() 
         .bigText(msg)) 
       .setContentText(msg) 
       .setPriority(Notification.PRIORITY_HIGH); 
mBuilder.setContentIntent(contentIntent); 
mBuilder.setAutoCancel(true); 

android.app.Notification note = mBuilder.build(); 
note.defaults |= android.app.Notification.DEFAULT_VIBRATE; 
note.defaults |= android.app.Notification.DEFAULT_SOUND;   

mNotificationManager.notify(0, note); 

现在，当我做我的处理我就可以调用finish（）或getActivity（）。结束（），它会带我回任何应用程序，你是在点击通知前/浏览器页面。

好that'sa有点怪异，但就像一个选项，可以在完成您的应用程序后打开浏览器。

private void allDone() { 
     Log.i(TAG, "The choice has been made");    
     getActivity().finish(); //finish your app!. 
     //NavUtils.navigateUpFromSameTask(getActivity()); 

     try { //Open browser!. 
      Uri uri = Uri.parse("googlechrome://navigate?url="); 
      Intent i = new Intent(Intent.ACTION_VIEW, uri); 
      i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      startActivity(i); 
     } catch (ActivityNotFoundException e) { 
      // Chrome is not installed 
     } 

} 

然后您将返回到Chrome会话;）。
