References to other resources are not supported by build-time PNG generation

Question

AndroidStudio 3.0 / Android Gradle plugin 3.0

Answer 1

Little bit more context for this error:

• Android 5.0 (API level 21) was the first version to officially support vector drawables.
• If you use minSdkVersion lower than 20, there are two solutions for vector drawable
  • Android Studio's Vector Asset Studio generate PNG. Please take a look Android Studio document. But, references to other resources are not supported by build-time PNG generation.
  • Use support library
• Or, use 21 or above for minSdkVersion

For support library, add a statement to your build.gradle file:

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

dependencies {
  compile 'com.android.support:appcompat-v7:23.2.0'
}
