Android debug签名和release签名

1.在APPmodule中的build.gradle中添加如下代码

 signingConfigs {
        release {
            keyAlias RELEASE_KEY_ALIAS
            keyPassword RELEASE_KEY_PASSWORD
            storeFile file(RELEASE_STORE_FILE)
            storePassword RELEASE_STORE_PASSWORD
        }
        debug{
            keyAlias RELEASE_KEY_ALIAS
            keyPassword RELEASE_KEY_PASSWORD
            storeFile file(RELEASE_STORE_FILE)
            storePassword RELEASE_STORE_PASSWORD
        }
    }

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

 android.applicationVariants.all { variant ->
        variant.outputs.all {
            outputFileName = "app_${variant.buildType.name}_V${variant.versionName}.apk"
        }
    }

2.在项目目录中的gradle.properties添加如下代码

RELEASE_KEY_PASSWORD=cccccc
RELEASE_KEY_ALIAS=bbbbbb
RELEASE_STORE_PASSWORD=aaaaa
RELEASE_STORE_FILE=D:/aaaaaaa/bbbbbb/cccccc/dddddd.jks

3.项目的gradle工具中编译
