android - 适用于 Android 4.4 的推送通知服务

Question

我已经完成了推送通知的工作，它的工作正常，但以防万一直到 api 级别 4.0。但是在 api 4.4 的情况下，通知点击不会打开 Activity ....我无法理解答案，我在 KitKat 上搜索并使用 Notification.Builder Api 来寻找通知，它给出了相同的结果。

private void generateNotification(Context context, String message, String id) {
    int icon = R.drawable.app_icon;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name);

    JSONObject jobj = new JSONObject();

    try {
        jobj.put("id", id);

    } catch (JSONException e) {
        e.printStackTrace();
    }
    System.out.println("json object" + jobj.toString());
    Intent notificationIntent = null;

    notificationIntent = new Intent(context, JamInfo.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    notificationIntent.putExtra("longi", longi);
    notificationIntent.putExtra("lati", lati);


    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    notification.setLatestEventInfo(context, title, message, intent);


    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notification.defaults |= Notification.DEFAULT_LIGHTS;
     }

    notificationManager.notify((int) System.currentTimeMillis(),
            notification);

}

This is working for my apps... Try this...

private void showNotification(Context context) {
        // TODO AK-generated method stub
        String appName = context.getString(R.string.app_name);
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                        .setSmallIcon(R.drawable.notification_icon)
                        .setContentTitle(appName)
                        .setContentText(appName);

        Uri sound = Uri.parse("android.resource://" + context.getPackageName() + "/raw/" + audioToneName);
        mBuilder.setSound(sound);
        mBuilder.setAutoCancel(true);
        mBuilder.setVibrate(Utility.vibrationPattern);
        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(context, RootActivity.class);
        // The stack builder object will contain an artificial back stack for
        // the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(RootActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                        0,
                        PendingIntent.FLAG_UPDATE_CURRENT
                        );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        mNotificationManager.notify(321, mBuilder.build());
    }
