当直接运行release版本时，报错Error: The apk for your currently selected variant cannot be signed. Please specify a signing configuration for this variant (package64-release).

 

解决报错：添加签名，signingConfigs 写在buildTypes前面，添加signingConfig signingConfigs.release

android {
 signingConfigs {
        debug {
            keyAlias 'xx'
            keyPassword 'xx'
            storeFile file('xx.jks')
            storePassword 'xx'
            v1SigningEnabled true
            v2SigningEnabled true
        }
        release {
            keyAlias 'xx'
            keyPassword 'zikao.2021'
            storeFile file('xx.jks')
            storePassword 'xx'
            v1SigningEnabled true
            v2SigningEnabled true
        }
    }

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