一、首先我們?cè)陧?xiàng)目根目錄建立一個(gè)project.properties自定義的簽名相關(guān)信息：

key.file=../filename.keystore
keyAlias=filealias
keyPassword=123456
storePassword=123456

二、然后在module的gradle中定義如下內(nèi)容：

 signingConfigs {

        debug {
            //加載資源
            Properties properties = new Properties()
            InputStream inputStream = project.rootProject.file('project.properties').newDataInputStream() ;
            properties.load( inputStream )
            //讀取文件
            def sdkDir = properties.getProperty('key.file')
            //讀取字段
            def key_keyAlias = properties.getProperty( 'keyAlias' )
            def key_keyPassword = properties.getProperty( 'keyPassword' ) ;
            def key_storePassword = properties.getProperty( 'storePassword' ) ;
            storeFile file(sdkDir)
            storePassword key_storePassword
            keyAlias key_keyAlias
            keyPassword key_keyPassword
        }

      /*  release {
            storeFile file( sdkDir )
            storePassword key_storePassword
            keyAlias key_keyAlias
            keyPassword key_keyPassword
        }*/
    }

當(dāng)然這樣做的最終目的是為了防止簽名信息暴露，最后不要把簽名文件放到項(xiàng)目下，而是類似C:\work\Key.jks這樣
