AAPT: error: resource android:attr/colorError not found

Question

I'm executing "tns run android" on a NativeScript project but I'm getting the following errors:

I'm new to NativeScript and to Android development. What are the recommended steps to debug/fix this error?

Answer 1

I believe colorError was introduced in support version 28.0.0. Since it looks like you're using 27.0.2 you can just use textColorError instead.

Answer 2

You need to change Android's SDK version to 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"  
  }  
}
