谷歌玻璃GDK：蓝牙发现意向 [英] Google Glass GDK: Bluetooth discoverable Intent

问题描述

我尽量让通过蓝牙我的谷歌玻璃发现在我的应用程序通过调用流动的意图：

 意图discoverableIntent =新意图（BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE）;
discoverableIntent.putExtra（BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION，120）;
startActivity（discoverableIntent）;
 

不过，我得到以下错误信息：

  

无法启动活动
  ComponentInfo {} com.example.glass/com.example.MainActivity：
  android.content.ActivityNotFoundException：无活动处理
  意向{行动= android.bluetooth.adapter.action.REQUEST_DISCOVERABLE
  （有临时演员）`}

有谁知道这个意图是由谷歌玻璃，现在还是不支持？

当然，我确信，我设置的权限在我的清单文件：

 ＆LT;使用许可权的android：NAME =android.permission.BLUETOOTH/＆GT;
＆LT;使用许可权的android：NAME =android.permission.BLUETOOTH_ADMIN/＆GT;
 

解决方案

这是错误发生，因为玻璃没有注册的处理显示针对该操作的用户界面的一项活动。

你能文件中我们的问题跟踪如果你需要这个？

I try to make my Google Glass discoverable via Bluetooth in my app by calling the flowing intent:

Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); 
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 120);
startActivity(discoverableIntent);

But I get the following error message:

Unable to start activity ComponentInfo{com.example.glass/com.example.MainActivity}: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.bluetooth.adapter.action.REQUEST_DISCOVERABLE (has extras)` }

Does anyone know if this intent is supported by Google Glass right now or not?

Of course I made sure that I set the permissions in my Manifest file:

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

解决方案

That error is occurring because Glass does not have an activity registered to handle displaying the UI for that action.

Can you file a feature request in our issue tracker if you need this?

In the meantime, have you explored the workaround in this post/answer to see if it would work for you?
