BrowserActivity 已泄露窗口

Question

我有一个使用 GCM 推送通知的应用。当我将通知推送到我正在测试的手机（HTC Desire C、三星迷你等）时，它工作正常。通知是修复了错误的应用的网址。

通常情况是收到推送，单击浏览器打开并开始下载。下载完成后，用户可以点击通知抽奖中的通知并安装/升级应用。

问题是当我尝试在 Motorola defy mini XT320 上运行它时。它可以接收推送，但浏览器在关闭之前打开大约一秒钟左右，并且没有开始下载。

有人知道为什么吗？以下是我如何生成通知以及错误。当浏览器打开时，我可以看到一个对话框弹出一瞬间。我知道该错误可能与此有关，因为它是泄漏的窗口错误。我没有创建此对话框，它是 Android 浏览器活动的一部分。

提前致谢。

 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);
        Intent notificationIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(message));


        // 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);     

    }

Answer 1

对于摩托罗拉 Defy Mini XT320 中的浏览器问题不是一个确切的解决方案（这实际上可能是正常操作，因为摩托罗拉可能已经决定在浏览器中设置限制以下载可疑文件，并且见鬼的文件.apk 扩展名可能非常危险），但您实际上可以直接请求DownloadManager 下载您的文件。

示例代码请参见https://stackoverflow.com/a/9033224/1893766。

Answer 2

我找到了下载管理器无法正常工作的原因，但仍不确定。

// Start download
     DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
     dm.enqueue(r);

        displayMessage(context, message);
        // notifies user
        generateNotification(context, message);

在上面的代码中，当我启动下载管理器时，对 displayMessage() 和 generateNotification() 的后续调用似乎会干扰下载。当我注释掉后续代码时，DownloadManager 似乎工作正常。就像我说不知道为什么。
