签名文件隐藏

1.在module下面新建一个keystore.properties文件

其中文件内容为

注意soreFile后直接跟签名文件的路径就可以，不需要加引号

2.在module下面的build.gradle中加入

//用于加载 keystore.properties 文件

def keystorePropertiesFile =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))

注意在android{}前引入

3.signingConfigs {

    config {  
 keyAlias keystoreProperties['keyAlias']
 keyPassword keystoreProperties['keyPassword']
 storeFile file(keystoreProperties['storeFile'])
 storePassword keystoreProperties['storePassword']
    }
4.

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
        signingConfig signingConfigs.config
    }
    debug {
        signingConfig signingConfigs.config
    }
}
