AAPT错误：未找到android:attr/colorError资源。

Question

我正在 NativeScript 项目中执行 "tns run android" 命令，但是我遇到了以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> Failed to process resources, see aapt output above for details.

我刚开始接触NativeScript和Android开发。如果出现错误，有什么推荐的调试/修复步骤吗？

Answer 1

我相信colorError是在支持版本28.0.0中引入的。既然你看起来正在使用27.0.2，你可以直接使用textColorError。

您需要将Android的SDK版本更改为26

app/App_Resources/Android/app.gradle

android {
  compileSdkVersion 26
  buildToolsVersion "26.0.3"
  defaultConfig {  
    generatedDensities = []
    applicationId = "org.nativescript.blankng"  
  }  
  aaptOptions {  
    additionalParameters "--no-version-vectors"  
  }  
}
