如何從服務中啓動ACTION_VOICE_COMMAND Intent？

Question

我有下面的代碼，推出在我服務的意圖：

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

我得到的錯誤

這裏是堆棧跟蹤：

我只是想在Android語音命令提示出現。我怎樣才能做到這一點？

Answer 1

看來你的「設備」中沒有人能夠通過操作ACTION_VOICE_COMMAND來處理該意圖。

您發佈的代碼是可以的。這是從服務推出Intents的正確方式。

Answer 2

你應該簡單地廣播這個意圖。然後系統抓住它並啓動語音命令應用程序。 Intent broadcast = new Intent（）; broadcast.setAction（Intent.ACTION_VOICE_COMMAND）; sendBroadcast（broadcast）;
