Question

我有以下代码在我的服务中启动Intent：

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

我收到错误

No Activity Found to Handle Intent

这是stacktrace：

我只想要出现Android Voice Command Prompt。我怎么能这样做？

Answer 1

似乎您的“设备”中没有人能够使用Action ACTION_VOICE_COMMAND处理该Intent。

您发布的代码没问题。这是从服务启动Intent的正确方法。

Answer 2

你应该只是广播意图。然后系统抓住它并启动Voice命令应用程序。 Intent broadcast = new Intent（）; broadcast.setAction（Intent.ACTION_VOICE_COMMAND）; sendBroadcast（广播）;

如何从服务中启动ACTION_VOICE_COMMAND Intent？
