应用关闭时打开启动活动的通知

Question

我正在我的应用程序中实施谷歌云消息服务（GCM）。我使用gcmIntent服务创建了一个挂起的意图并打开了一个不是启动活动的活动。当应用程序打开时，它工作正常。但当应用程序关闭时，它会打开启动活动而不是所需的活动。我尝试了我能找到的所有解决方案，但都不起作用。我挣扎了一个多星期。任何帮助都将不胜感激。

我的代码

public class GcmIntentService extends IntentService {
    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    Notification notification;
    NotificationCompat.Builder builder;

public GcmIntentService() {
    super("GcmIntentService");
}
public static final String TAG = "GCM Demo";

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  

        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {

        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {


        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            String [] message={extras.getString("abc"),extras.getString("zyx"),extras.getString("123"),extras.getString("456")};
            if(UserDetails.getPushNotificationStatus(this)){
                sendNotification(message);
            }
        }
    }
    GCMBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String[] msg) {
    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(getBaseContext(), ShowShoutComment.class);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent contentIntent =
            PendingIntent.getActivity(getBaseContext(), 0, notificationIntent, 0);

    Uri notificationUri = RingtoneManager
            .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.ic_launcher)
    .setLargeIcon(remote_picture)
    .setContentText(Html.fromHtml(msg[2]))
    .setContentTitle("Shout")
    .setSound(notificationUri)
    .setStyle(new      NotificationCompat.BigTextStyle().bigText(Html.fromHtml(msg[2])));

    mBuilder.setContentIntent(contentIntent);
    notification = new Notification();
    notification = mBuilder.build();
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.flags |= Notification.FLAG_SHOW_LIGHTS;
    notification.defaults |= Notification.DEFAULT_LIGHTS;
    mNotificationManager.notify(NOTIFICATION_ID, notification);

}
}

我得到下面的堆栈跟踪

Answer 1

做了一些改变。

private void sendNotification(Context context,String[] msg) {

   ....
   Intent notificationIntent = new Intent(context, ShowShoutComment.class);
   ....
   PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
   ...    
}

Answer 2

把它放在你的上面（服务类）

Intent intent2 = new Intent(context, yourDesiredActivity.class);
intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pIntent = PendingIntent.getActivity(context, 0, intent2, 0); 

希望这对你有帮助。
