優化Android Studio/Gradle構建

       使用Android Studio進行開,隨着項目的增大,依賴庫的增多,構建速度愈來愈慢,如今最慢要6分鐘才能build一個release的安裝包,在網上查找資料,發現能夠經過一些配置能夠加快速度,這裏跟你們分享一下。

 

開啓gradle單獨的守護進程

在下面的目錄下面建立gradle.properties文件:html

  • /home/<username>/.gradle/ (Linux)
  • /Users/<username>/.gradle/ (Mac)
  • C:\Users\<username>\.gradle (Windows)
  • 把下面配置複製gradle.properties文件也能夠優化:
    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
    複製代碼
    同時上面的這些參數也能夠配置到前面的用戶目錄下的gradle.properties文件裏,那樣就不是針對一個項目生效,而是針對全部項目生效。
    上面的配置文件主要就是作, 增大gradle運行的java虛擬機的大小,讓gradle在編譯的時候使用獨立進程,讓gradle能夠平行的運行。

    1.申請大內存java

    installation path\studio64.exe.vmoptions or studio.exe.vmoptionsjvm

    使用文本編輯器打開,找到起始兩行,以下編輯器

    -Xms128m
    -Xmx750m
    ide


    修改最小值和最大值,建議爲測試

    -Xms256m
    -Xmx2048m
    gradle

    2 優化編譯優化

     file->setting->compileui

     勾選除第二項以外的其餘選項,並在VM options裏填入:this

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


通過測試,編譯速度有很大提高,比較大的項目從以前的5-8分鐘能夠減小到1-2分鐘。
