android build错误链接资源失败

Question

我卸载了先前版本的android，然后安装了version3.0.1，我在android studio中创建了一个新应用，但我没有修改任何代码，但是当我尝试构建项目时，出现以下错误

Error:resource style/Theme.AppCompat.Light.DarkActionBar (aka com.example.android.my:style/Theme.AppCompat.Light.DarkActionBar) not found.
C:\AndroidStudioProjects\MyAPP\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml

> Failed to execute aapt

这是我的build.gradle档案

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
defaultConfig {
    applicationId "com.example.android.my"
    minSdkVersion 21
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
   "android.support.test.runner.AndroidJUnitRunner"
}
  buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'p 
        roguard-rules.pro'
    }
  }
}

 dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:26.1.0'
   implementation 'com.android.support.constraint:constraint-layout:1.0.2'
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'com.android.support.test:runner:1.0.1'
   androidTestImplementation 'com.android.support.test.espresso:espresso-
  core:3.0.1'
 }

这是我的values.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr format="reference" name="constraintSet"/>
<attr format="integer" name="layout_constraintBaseline_creator"/>
  ..... some codes here ....
 <attr format="dimension" name="layout_goneMarginTop"/>
 <attr name="layout_optimizationLevel">
     <flag name="none" value="1"/>
     <flag name="all" value="2"/>
     <flag name="basic" value="4"/>
     <flag name="chains" value="8"/>
 </attr>
 <color name="colorAccent">#FF4081</color>
 <color name="colorPrimary">#3F51B5</color>
 <color name="colorPrimaryDark">#303F9F</color>
  <declare-styleable name="ConstraintLayout_Layout"><attr name="android:orientation"/><attr name="android:minWidth"/>
  .... some more attributes here ....

<string name="app_name">MyAppName</string>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
      <!-- Customize your theme here. -->
      <item name="colorPrimary">@color/colorPrimary</item>
       <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
       <item name="colorAccent">@color/colorAccent</item>
   </style>
</resources>

似乎该错误是Android Studio中的一些奇怪行为，我已使缓存无效并重新启动了项目，但问题仍然存在，我该如何解决此问题？

如果有人阅读有同样的问题，这最近发生在我身上，这是由于xml标头被错误地写入了两次：

<?xml version="1.0" encoding="utf-8"?>
<?xml version="1.0" encoding="utf-8"?> <!-- Remove this one -->
<shape xmlns:android="http://schemas.android.com/apk/res/android">
     <solid android:color="@color/mug_blue"/>
     <corners android:radius="@dimen/featured_radius" />
</shape>

我遇到的错误与该文件完全无关，因此很难找到。只需确保所有新的xml文件都没有类似这样的错误（因为它不会显示为错误）。
