Android Studio Gradle Build Running 特别慢的问题探讨

在运行程序的时候Gradle Build Running 特别慢，一个helloworld都快2min了

1、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)

并在文件中增加：

org.gradle.daemon=true

同时修改项目下的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 serversorg.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=256morg.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_projectsorg.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_demandorg.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。

2、修改android studio配置

在android studio的配置中，开启offline模式，以及修改配置。实际上的配置和上面的一大段一样，主要是在这个地方配置的只会在ide构建的时候生效，命令行构建不会生效。
