如何的Andr​​oid开始从通知抽屉里的APK下载 [英] Android how to start an apk download from the notification drawer

问题描述

我有一个应用程序，我可以通过GCM上推送通知。我收到通知抽屉里的通知，但是当我点击它，从应用的活动开始（EntryActivity）。我想发生的情况是，如果在通知中的消息是URL到.apk文件如 HTTP：//path_to_file.apk '，然后我想将文件开始下载。

下面是code产生的通知，有什么我需要添加或更改开始下载？

        NotificationManager notificationManager =（NotificationManager）
                context.getSystemService（Context.NOTIFICATION_SERVICE）;
        通知通知=新的通知（图标，消息，时）;        字符串title = context.getString（R.string.app_name）;
        意图notificationIntent =新意图（背景下，EntryActivity.class）;        //设置的意图，因此它不会启动新活动
        notificationIntent.setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP）;
        的PendingIntent意图=
                PendingIntent.getActivity（上下文，0，notificationIntent，0）;
        notification.setLatestEventInfo（上下文，标题，邮件，意图）;
        notification.flags | = Notification.FLAG_AUTO_CANCEL;        //播放默认通知声音
        notification.defaults | = Notification.DEFAULT_SOUND;        //如果振动启用震动
        notification.defaults | = Notification.DEFAULT_VIBRATE;
        notificationManager.notify（0，通知）;    }
 

解决方案

试试这个：

 意图notificationIntent =新意图（Intent.ACTION_VIEW，Uri.parse（HTTP：//path_to_file.apk））;
    notificationIntent.setClassName（com.android.browser
                                com.android.browser.BrowserActivity）;
 

I've an app that i can push notifications on to via GCM. I receive the notification in the notification drawer but when i click on it, an activity from the app is started(EntryActivity). What i'd like to happen is if the message in the notification is a url to the .apk file eg 'http://path_to_file.apk', then i'd like the file to start downloading.

Below is the code that generates the notification, is there something i need to add or change to start the download?

/**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message) {
        int icon = R.drawable.ic_launcher;
        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);


        Intent notificationIntent = new Intent(context, EntryActivity.class);

        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =
                PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;

        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);     

    }

解决方案

Try this:

    Intent notificationIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://path_to_file.apk"));
    notificationIntent.setClassName("com.android.browser",
                                "com.android.browser.BrowserActivity");
