Android gradle:buildtoolsVersion 与 compileSdkVersion

Android gradle: buildtoolsVersion vs compileSdkVersion(Android gradle:buildtoolsVersion 与 compileSdkVersion)

问题描述

Android 项目的 build.gradle 中的 buildtoolsVersion 与 compileSdkVersion 有什么区别?

What's the difference between buildtoolsVersion vs compileSdkVersion in the build.gradle for an Android project?

具体来说，我想澄清一下构建工具是什么?

Specifically, I'd like clarification on what the build tool is?

推荐答案

compileSdkVersion 是您编译的 Android API 版本.

compileSdkVersion is the API version of Android that you compile against.

buildToolsVersion 是您要使用的编译器(aapt、dx、renderscript 编译器等)的版本.对于每个 API 级别(从 18 开始)，都有一个匹配的 .0.0 版本.

buildToolsVersion is the version of the compilers (aapt, dx, renderscript compiler, etc...) that you want to use. For each API level (starting with 18), there is a matching .0.0 version.

在 IO 2014 上，我们发布了 API 20 和构建工具 20.0.0.

At IO 2014, we release API 20 and build-tools 20.0.0 to go with it.

在 Android 版本之间，我们将发布编译器的更新，因此我们将发布 .0.1、.0.2 等版本...因为我们不想在您的领导下默默更新这些版本，所以由您决定方便时移至新版本.

Between Android releases we will release updates of the compilers, and so we'll release version .0.1, .0.2, etc... Because we don't want to silently update these version under you, it's up to you to move to the new version when it's convenient for you.

您可以使用比您的 compileSdkVersion 更高版本的构建工具，以便在不更改构建应用程序的基础上选择新的/更好的编译器.

You can use a higher version of the build-tools than your compileSdkVersion, in order to pick up new/better compiler while not changing what you build your app against.
