【Android】release 签名

点击Build Variants中的Active Build Variant中的变量状态，切换到release时，会异常，app处有个红叉，需给App添加签名

    signingConfigs {
        release {
            keyAlias 'key0'
            keyPassword 'test'
            storeFile file('../test.jks')
            storePassword 'test'
        }
    }

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