開啟gradle單獨的守護進程

在下面的目錄下面建立gradle.properties檔案：

• /home/<username>/.gradle/ (Linux)
• /Users/<username>/.gradle/ (Mac)
• C:\Users\<username>\.gradle (Windows)
• 把下面配置複製gradle.properties檔案也可以最佳化：

# 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

 

同時上面的這些參數也可以配置到前面的使用者目錄下的gradle.properties檔案裡，那樣就不是針對一個項目生效，而是針對所有項目生效。上面的設定檔主要就是做， 增大gradle啟動並執行java虛擬機器的大小，讓gradle在編譯的時候使用獨立進程，讓gradle可以平行的運行。

1.申請大記憶體

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

使用文字編輯器開啟，找到起始兩行，如下

-Xms128m
-Xmx750m

 

修改最小值和最大值，建議為

-Xms256m
-Xmx2048m

 

最佳化編譯

     file->setting->compile

     勾選除第二項之外的其他選項，並在VM options裡填入：

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

 

經過測試，編譯速度有很大提升，比較大的項目從之前的5-8分鐘可以減少到1-2分鐘
