local.properties文件在Android Studio中是用来配置SDK目录的,也可以在文件中配置一些本地化的变量。这个文件不会被提交到版本控制中。

为了安全起见签名文件不可以放在项目中，那么可能每个开发人员的存放地方不同，这种情况下就可以使用local.properties来配置路径然后在app目录下的build.gradle中引用。

sdk.dir=/Users/baiduo/Library/Android/sdk

#配置keystore文件路径

RELEASE_STORE_FILE=/Users/baiduo/Desktop/Lottery

在build.gradle中引用：

signingConfigs {

autoSigning {

#加载properties

def properties = new Properties()

def inputStream = project.rootProject.file('local.properties').newDataInputStream()

properties.load( inputStream )

keyAlias 'IKicker'

keyPassword '*******'

storeFile file(properties.getProperty('RELEASE_STORE_FILE'))

storePassword '*******'

}

}
