优化Android Studio/Gradle构建 - 黑马程序员技术交流社区

开启gradle单独的守护进程

在下面的目录下面创建gradle.properties文件：

/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)
把下面配置复制gradle.properties文件也可以优化：
1. # Project-wide Gradle settings.
2. # IDE (e.g. Android Studio) users:
3. # Settings specified in this file will override any Gradle settings
4. # configured through the IDE.
5. # For more details on how to configure your build environment visit
6. # http://www.gradle.org/docs/current/userguide/build_environment.html
7. # The Gradle daemon aims to improve the startup and execution time of Gradle.
8. # When set to true the Gradle daemon is to run the build.
9. # TODO: disable daemon on CI, since builds should be clean and reliable on servers
10. org.gradle.daemon=true
11. # Specifies the JVM arguments used for the daemon process.
12. # The setting is particularly useful for tweaking memory settings.
13. # Default value: -Xmx10248m -XX:MaxPermSize=256m
14. org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
15. # When configured, Gradle will run in incubating parallel mode.
16. # This option should only be used with decoupled projects. More details, visit
17. # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
18. org.gradle.parallel=true
19. # Enables new incubating mode that makes Gradle selective when configuring projects.
20. # Only relevant projects are configured which results in faster builds for large multi-projects.
21. # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
22. org.gradle.configureondemand=true

同时上面的这些参数也可以配置到前面的用户目录下的gradle.properties文件里，那样就不是针对一个项目生效，而是针对所有项目生效。
上面的配置文件主要就是做，增大gradle运行的java虚拟机的大小，让gradle在编译的时候使用独立进程，让gradle可以平行的运行。
1.申请大内存
installation path\studio64.exe.vmoptions or studio.exe.vmoptions
使用文本编辑器打开，找到起始两行，如下
-Xms128m
-Xmx750m

修改最小值和最大值，建议为
-Xms256m
-Xmx2048m

2 优化编译

file->setting->compile

勾选除第二项之外的其他选项，并在VM options里填入：

-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

经过测试，编译速度有很大提升，比较大的项目从之前的5-8分钟可以减少到1-2分钟。
