如何在"辅助和语音输入选项"下的"辅助"应用中列出Android应用

Question

我有一个将语音转换为文本的应用程序。但是我希望该行为像Google Assist Asscepp一样，即我希望在触发默认语音辅助应用程序触发时调用我的应用程序。语音输入选项。请帮助我找出以下代码中现有的更改，以便在Assist App选项中列出它，并且手机将其作为默认应用程序。预先感谢。

Answer 1

尝试将这些行添加到活动的意图过滤器中：

<action android:name="android.intent.action.ASSIST" />
<category android:name="android.intent.category.DEFAULT" />
