I updated to the latest Android N sdk. The only thing I don't understand is why I cannot import java.time into my code? I thought Java8 is available through Android N. Then why didn't Google add java.time package?

Starting from Android Gradle Plugin 4.0.0, we can finally use proper java.time package classes without worries (almost): https://developer.android.com/studio/write/java8-support

Optional, java.time, streams, and more are desugared into Java 7 by the Android Gradle Plugin.

To add those classes support, you just need to add a few lines to your build file:

android {
  defaultConfig {
    // Required when setting minSdkVersion to 20 or lower
    multiDexEnabled true
  }

  compileOptions {
    // Flag to enable support for the new language APIs
    coreLibraryDesugaringEnabled true
    // Sets Java compatibility to Java 8
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

dependencies {
  coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.0.9'
}
