apk签名配置

build.gradle文件中增加如下的配置：

// Create a variable called keystorePropertiesFile, and initialize it to your
// keystore.properties file, in the rootProject folder.
def keystorePropertiesFile = rootProject.file("keystore.properties")
// Initialize a new Properties() object called keystoreProperties.
def keystoreProperties = new Properties()
// Load your keystore.properties file into the keystoreProperties object.
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android {
    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }
}

注意“keystore.properties”文件是在项目的根目录，其内容如下：

storePassword=guiying712
keyPassword=guiying712
keyAlias=guiying712
storeFile=/mykey.jks
