Question

我无法通知打开应用。我已按照Android文档上的说明操作，但无济于事。它创建通知没有问题，但点击它只是解雇它。

请帮忙！提前谢谢！

为什么点击不打开应用的通知？

Intent intent = new Intent(this, MainActivity.class);

    String type = "";
    if (extras.containsKey(KEY_TYPE)) type = extras.getString(KEY_TYPE);

    String text = "";

    if (type.equalsIgnoreCase(TYPE_MATCH_FOUND)) {
        // TODO: send intent with all variables, trigger matched fragment when user goes into app



        text = getResources().getString(R.string.msg_found_match);

        intent.putExtra(KEY_TYPE, TYPE_MATCH_FOUND);
    }
    else if (type.equalsIgnoreCase(TYPE_MESSAGE)) {
        // TODO: trigger chat fragment when user goes into app

        text = getResources().getString(R.string.msg_new_message_from);

        intent.putExtra(KEY_TYPE, TYPE_MESSAGE);
    }

    mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);        

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("LFDate")
        .setContentText(text)
        .setAutoCancel(true)
        .setLights(Color.parseColor("#0086dd"), 2000, 2000);

    if (prefs.getNotificationVibrate()) mBuilder.setVibrate(new long[] {1000, 1000, 1000});
    if (prefs.getNotificationSound()) mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addParentStack(MainActivity.class);
    stackBuilder.addNextIntent(intent);

    PendingIntent contentIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

我今天早些时候遇到了同样的问题，如果你使用kitkat，你将不得不改为：

// Have pending intent use FLAG_CANCEL_CURRENT, cause on 
// kitkat you get a permission denied error
PendingIntent contentIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_CANCEL_CURRENT);

mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

或者您可以将标记添加到接收方，或者以XML格式通知启动的活动：

 android:exported="true"

单击通知不打开应用/活动
