如何從服務啟動ACTION_VOICE_COMMAND Intent？

Question

我有以下代碼在我的服務中啟動Intent：

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

我得到了錯誤

No Activity Found to Handle Intent

這是堆棧跟蹤：

我只希望顯示Android語音命令提示符。 我怎樣才能做到這一點？

Answer 1

您應該只廣播意圖。 然后系統抓取它並啟動“語音”命令應用程序。 意圖廣播= new Intent（）; broadcast.setAction（Intent.ACTION_VOICE_COMMAND）; sendBroadcast（廣播）;

Answer 2

您的“設備”中似乎沒有人能夠使用Action ACTION_VOICE_COMMAND處理該Intent。

您發布的代碼還可以。 這是從服務啟動Intent的正確方法。
