android studio 生成带签名和指定名称的APK

    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
    signingConfigs {
        release {
            keyAlias 'androiddebugkey'
            keyPassword 'android'
            storeFile file('D:\\my_path\\xxxxx.jks')//签名文件的路径
            storePassword 'android'
        }
    }

......

    buildTypes {
        release {
            minifyEnabled true//是否启动混淆 ture:打开   false:关闭
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release//release版本
        }
        debug {
            signingConfig signingConfigs.release//debug版本也使用签名
        }
    }

    //生成指定名称的APK
    android.applicationVariants.all {
        variant -> variant.outputs.all { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                outputFileName = "myApp_" + buildType.name + "_v${defaultConfig.versionName}.apk"
            }
        }
    }
