如何从服务中启动ACTION_VOICE_COMMAND Intent？

Question

我有下面的代码，推出在我服务的意图：

Intent voiceCommandIntent = new Intent(Intent.ACTION_VOICE_COMMAND); 
      voiceCommandIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      appContext.startActivity(voiceCommandIntent); 

我得到的错误

这里是堆栈跟踪：

我只是想在Android语音命令提示出现。我怎样才能做到这一点？

Answer 1

看来你的“设备”中没有人能够通过操作ACTION_VOICE_COMMAND来处理该意图。

您发布的代码是可以的。这是从服务推出Intents的正确方式。

Answer 2

你应该简单地广播这个意图。然后系统抓住它并启动语音命令应用程序。 Intent broadcast = new Intent（）; broadcast.setAction（Intent.ACTION_VOICE_COMMAND）; sendBroadcast（broadcast）;
