• 优化Android Studio/Gradle构建


    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:

    # Project-wide Gradle settings.
    # IDE (e.g. Android Studio) users:
    # Settings specified in this file will override any Gradle settings
    # configured through the IDE.
    # For more details on how to configure your build environment visit
    # http://www.gradle.org/docs/current/userguide/build_environment.html
    # The Gradle daemon aims to improve the startup and execution time of Gradle.
    # When set to true the Gradle daemon is to run the build.
    # TODO: disable daemon on CI, since builds should be clean and reliable on servers
    org.gradle.daemon=true
    # Specifies the JVM arguments used for the daemon process.
    # The setting is particularly useful for tweaking memory settings.
    # Default value: -Xmx10248m -XX:MaxPermSize=256m
    org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
    # When configured, Gradle will run in incubating parallel mode.
    # This option should only be used with decoupled projects. More details, visit
    # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
    org.gradle.parallel=true
    # Enables new incubating mode that makes Gradle selective when configuring projects.
    # Only relevant projects are configured which results in faster builds for large multi-projects.
    # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
    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 pathstudio64.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

    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
