How do I update the Java Development Kit (JDK) version?

  • Artikkeli

This article illustrates how to update the Java Development Kit (JDK) version on Windows and Mac.

Overview

Xamarin.Android uses the Java Development Kit (JDK) to integrate with the Android SDK for building Android apps and running the Android designer. The latest versions of the Android SDK (API 24 and higher) require JDK 8 (1.8). Alternately, you can install the Microsoft Mobile OpenJDK Preview. The Microsoft Mobile OpenJDK will eventually replace JDK 8 for Xamarin.Android development.

To update to the Microsoft Mobile OpenJDK, see Microsoft Mobile OpenJDK Preview. To update to JDK 8, follow these steps:

  1. Download JDK 8 (1.8) from the Oracle website:
