我开始学习android NDK,我立即遇到了问题.

我构建了工具链(花了比我预期的更长的时间!!)并且我编译了C++代码没有任何问题,现在我正在尝试构建java代码.

我立即遇到了问题.有一个文件"main.xml"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
<TextView  
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="Hello World, DemoActivity"
    />
</LinearLayout>

我收到以下错误:
