我创建了一段代码来获取用户的活动信息，以查看他是在步行、驾车还是静止不动，但它没有起作用，onHandleIntent从未被调用。它正在连接到GoogleApiClient。
这是我的代码：
活动布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView android:text="@string/hello_world" android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/msg" />

}
};

}
}

大家好，请帮忙，谷歌文档对于活动识别没什么用处。
onHandleIndent，但在我另一部运行较低版本的安卓手机上可以正常工作。正如你所说，可能是传感器出了问题。顺便说一下，这个设备是红米Note，目前无法正常工作。 - Saqueib
