android - 错误 :(9) Error: Suspicious namespace and prefix combination [NamespaceTypo] when building signed apk release

Question

我已经在线检查了一个解决方案，尝试过此页面的解决方案:Error: Suspicious namespace and prefix combination [NamespaceTypo] when I try create Signed APK还有errors in hello world xml但没有解决办法。有趣的是，当我尝试构建应用程序调试或电视版本时，一切正常。错误:

  (9) Error: Suspicious namespace and prefix combination [NamespaceTypo]
  xmlns:app="http://schemas.android.com/tools"
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  Explanation for issues of type "NamespaceTypo":
  Accidental misspellings in namespace declarations can lead to some very
 obscure error messages. This check looks for potential misspellings to  help track these down.
  1 errors, 0 warnings

布局文件部分代码:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"> 

解决这个问题很有帮助
