1.配置 productFlavors

productFlavors {
        _dev {//开发环境
            applicationId "com.demo.video.dev"
            //设置baseUrl 使用方法Application.getContext().getResources().getString(R.string.API_SERVER)
            resValue "string","API_SERVER","www.baidu.dev.com"
            manifestPlaceholders = [app_name: "U视频_dev"]
        }

        _test {//测试环境
            applicationId "com.demo.video.test"
            resValue "string","API_SERVER","www.baidu.test.com"
            manifestPlaceholders = [app_name: "U视频_test"]

        }

        _prod {//正式环境
            applicationId "com.demo.video"
            resValue "string","API_SERVER","www.baidu.com"
            manifestPlaceholders = [app_name: "U视频"]
        }
    }

2.配置APK输入路径 （可配置或者不配置 默认在build/outputs下）

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

        debug {
            minifyEnabled false
            signingConfig signingConfigs.config
            debuggable true
        }

        //打包输出
        applicationVariants.all { variant ->
            def fileName
            def buildName
            variant.outputs.each { output ->
                def outputFile = output.outputFile
                variant.productFlavors.each { product ->
                    buildName = product.name //获取渠道名字
                }

                if (outputFile != null && outputFile.name.endsWith('.apk')) {
                    //打包后的apk名称 ： UVideo_V1.0_test_0808_1109.apk
                    fileName = "UVideo_V${defaultConfig.versionName}" + buildName + "_" + createDate() + ".apk"
                    output.outputFile = new File("apk" + '/', fileName)

                }
            }
        }
    }

//获取时间的方法
def createDate() {
    return new Date().format("MMdd_HHmm", TimeZone.getTimeZone("GMT+8"))
}

3.打包

使用AndroidStudio可在Terminal下输入./gradlew assembleRelease
或者输入对应的./gradlew assemble_dev
也可在右侧Gradle中选中要打包的版本执行

4.安装/测试应用

1.使用ADB
可在终端下输入 adb install apk路径
即可
2.使用Gradle
在右侧Gradle下选择install目录下对应的版本运行即可
