AndroidStudio使用全新的构建系列—–Gradle。
这是官方为什么使用gradle 的理由：
- Domain Specific Language (DSL) to describe and manipulate the build logic
- Build files are Groovy based and allow mixing of declarative elements through the DSL and using code to manipulate the DSL elements to provide custom logic.
- Built-in dependency management through Maven and/or Ivy.
- Very flexible. Allows using best practices but doesn’t force its own way of doing things.
- Plugins can expose their own DSL and their own API for build files to use.
- Good Tooling API allowing IDE integration
在Ubuntu安装Gradle也是很简单。切记请勿使用apt-get安装Gradle。因为Ubuntu源的Gradle实在太旧。我用的搜狐的源，竟然是2011年。
下面是安装步骤：
1、在官网下载最新的Gradle版本。http://www.gradle.org/downloads
2、解压安装包到目录
3、
打开环境文件
sudo vim /etc/profile
4、写入环境变量:
export GRADLE_HOME=/opt/gradle/gradle-2.0
export PATH=$GRADLE_HOME/bin:$PATH
5、环境变量生效source /etc/profile
6、检查结果
gradle -v
