一、开发工具
使用软件Android Studio 4.1版本

1、软件介绍
Android Studio 是基于 IntelliJ IDEA 的官方 Android 应用开发集成开发环境 (IDE)。除了 IntelliJ 强大的代码编辑器和开发者工具,Android Studio 提供了更多可提高 Android 应用构建效率的功能,例如:
基于 Gradle 的灵活构建系统
快速且功能丰富的模拟器
可针对所有 Android 设备进行开发的统一环境
Instant Run,可将变更推送到正在运行的应用,无需构建新的 APK
可帮助您构建常用应用功能和导入示例代码的代码模板和 GitHub 集成
丰富的测试工具和框架
可捕捉性能、易用性、版本兼容性以及其他问题的 Lint 工具
C++ 和 NDK 支持
内置对 Google 云端平台的支持,可轻松集成 Google Cloud Messaging 和 App 引擎
2、Android JDK配置




3、Android Gradle配置
