已經使用Android Studio進行開發超過一年,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。 html
在下面的目錄下面建立gradle.properties文件: java
/home/<username>/.gradle/ (Linux) android
/Users/<username>/.gradle/ (Mac) jvm
C:\Users\<username>\.gradle (Windows) ide
並在文件中增長: gradle

org.gradle.daemon=true

同時修改項目下的gradle.properties文件也能夠優化: 優化

# 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
# 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.

org.gradle.configureondemand=true

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。 ui
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。 this
在android studio的配置中,開啓offline模式,以及修改配置。實際上的配置和上面的一大段同樣,主要是在這個地方配置的只會在ide構建的時候生效,命令行構建不會生效。 spa
