使用 Microsoft Band 保持连接打开

Question

我正在开发一个应用程序，通过按下你手环上的按钮，用你的 phone 拍照。当您运行处于发布模式的应用程序时，会出现一个奇怪的问题。

当我运行应用程序处于调试模式时，我能够保持连接打开以侦听 Band 事件。但是当我在发布模式下构建时，不再触发 TileButtonPressed 事件。我不知道这是错误还是我的连接方式不正确。如果我以错误的方式连接，只要应用运行ning，我应该如何保持连接打开？

客户端变量用于class中的各种函数。

这是我用来连接和侦听事件的代码。

    private async void BandConnection()
    {
        btnRetry.Visibility = Visibility.Collapsed;
        grStatus.Visibility = Visibility.Visible;
        tbStatus.Text = "Looking for your Band...";
        if (!await HasBand())
        {
            btnRetry.Visibility = Visibility.Visible;
            tbStatus.Text = "No Band detected!";
            return;
        }
        tbStatus.Text = "Connecting...";
        client = await BandClientManager.Instance.ConnectAsync(getPairedDevice[0]);
        tbStatus.Text = "Connected!";
        string bandVersion = await client.GetFirmwareVersionAsync();
        string bandHWversion = await client.GetHardwareVersionAsync();

        Debug.WriteLine("Band FW version: " + bandVersion);
        Debug.WriteLine("Band HW version: " + bandHWversion);
        current = Window.Current.Dispatcher;
        await client.TileManager.StartReadingsAsync();

        client.TileManager.TileButtonPressed += async (sender, e) =>
        {
            var buttonId = e.TileEvent.ElementId;
            var pageId = e.TileEvent.PageId;
            var tileId = e.TileEvent.TileId;
            Debug.WriteLine(buttonId + " - " + pageId + " - " + tileId);
            if (buttonId == 1)
            {
                // Take picture
                await current.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () => {
                    await TakePhotoAsync();

                });
            }
            if (buttonId == 2)
            {
                // Record video
                await current.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () => {
                    if (!_isRecording)
                    {
                        await StartRecordingAsync();
                    }
                    else
                    {
                        await StopRecordingAsync();
                    }

                    // After starting or stopping video recording, update the UI to reflect the MediaCapture state
                    UpdateCaptureControls();

                });
            }
            if (buttonId == 3)
            {
                // Toggle flash
                await current.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () => {
                    ToggleFlash();
                });
            }

            if (buttonId == 4)
            {
                await current.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () => {
                    SwitchCamera();
                });
            }
        };
        grStatus.Visibility = Visibility.Collapsed;

    }

好的，我就此问题联系了 Microsoft Band 团队，这是他们的回复：

This is a known issue with the UWP apps built with the .net native compilation >option (default for release builds).

We have a fix that we will be pushing out soon. Until then plz continue to build >debug.
