  1. POHow should i do from notification back to activity without new intent
    text
    copied!<p>from Android Development, i implement a simple notification by the sample code, but in my app, i don't want to new intent and create the activity again, i just want to back to my last activity(it's a mediaplayer UI). if i use the sample code, it will create a new activity by</p> <pre><code>Intent resultIntent = new Intent(this, ResultActivity.class); </code></pre> <p>i comment relative code about new intent and got a notification, but didn't have idea how to back to my last activity... </p> <p>back to my app from long press home key and touch my app is OK. what i want is just like this behavior.</p> <p>bleow is the sample code from Android Development, i comment the new intent portion.</p> <pre><code>NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.notification_icon) .setContentTitle("My notification") .setContentText("Hello World!"); /*Intent resultIntent = new Intent(this, ResultActivity.class); TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); stackBuilder.addParentStack(ResultActivity.class); stackBuilder.addNextIntent(resultIntent); PendingIntent resultPendingIntent = stackBuilder.getPendingIntent( 0, PendingIntent.FLAG_UPDATE_CURRENT ); mBuilder.setContentIntent(resultPendingIntent);*/ NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(mId, mBuilder.build()); </code></pre> <h1>[UPDATE]</h1> <p>i thought i need to set flag for intent and properity for activity. therefore, for the activity i want to back to i set</p> <pre><code>android:launchMode="singleInstance" </code></pre> <p>and because, i don't want a new activity from intent, i just want my last activity, so i add</p> <pre><code>Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY </code></pre> <p>from documentation i got that using <strong>Pendingintent.contentIntent</strong> it must include the <strong>FLAG_ACTIVITY_NEW_TASK</strong> flag and When using this flag, if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in. so i also add </p> <pre><code>Intent.FLAG_ACTIVITY_NEW_TASK </code></pre> <p>but from logCat, i still saw that when i touch the notification for back to activity, the pendingintent still called onCreate() function rather than just show the last activity which still "alive".</p>
