Question

我已经完成了关于推送通知及其正常工作的工作，但是直到api级别4.0。但是在api 4.4的情况下，通知点击不会打开活动....我无法理解答案，我在KitKat上搜索并且通知它已经使用了Notification.Builder Api，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());
    }

尝试以下内容：

        private final static int NOTIFICATION_ID = 1;
        private static NotificationManager mNotificationManager;

        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
            // API 16 onwards
            Notification.Builder builder = new Notification.Builder(context);
            builder.setAutoCancel(false)
                .setContentIntent(pendingIntent)
                .setContentText(context.getString(R.string.notification_text))
                .setContentTitle(context.getString(R.string.app_name))
                .setOngoing(true)
                .setSmallIcon(R.drawable.ic_notifier)
                .setWhen(System.currentTimeMillis());
            Notification notification = builder.build();
            notification.flags |= Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
            mNotificationManager.notify(NOTIFICATION_ID, notification);         
        } else {
            // API 15 and earlier
            NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
            builder.setAutoCancel(false)
                .setContentIntent(pendingIntent)
                .setContentText(context.getString(R.string.notification_text))
                .setContentTitle(context.getString(R.string.app_name))
                .setOngoing(true)
                .setSmallIcon(R.drawable.ic_notifier)
                .setWhen(System.currentTimeMillis());
            Notification notification = builder.getNotification();
            notification.flags |= Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
            mNotificationManager.notify(NOTIFICATION_ID, notification);         
        }

在适当的位置添加JSON部分。并且不要忘记将 android-support-v4.jar 添加到您的项目中，否则它将无法编译。
