gradle多渠道打包

实战场景两个：
1.使用Umeng打多个渠道包。
2.应用生成 正式站、测试站两个版本，一下分别介绍。

成功打包的几个注意事项：
1.仔细看gradle-wapper的版本：文件位置：根目录\gradle\wrapper\gradle-wrapper.properties
仔细看gradle插件的版本：文件位置：根目录\build.gradle
不同的gradle版本和gradle插件版本，相应api会发生变化
我使用的gradle:gradle-3.3 plugin:'com.android.tools.build:gradle:2.3.3'
2.Manifest.xml文件中，渠道号的写法。
android:name="UMENG_CHANNEL"
android:value="${UMENG_CHANNEL_VALUE}" />
3.keystore文件。位置：根目录\app\xxx.keystore
4.app moudle下build.gradle的配置。
a.配置签名信息。

        release {
            v1SigningEnabled true
            v2SigningEnabled false
            storeFile file("easaa_useinterface.keystore")
            storePassword "easaa.com"
            keyAlias "easaa.keystore"
            keyPassword "easaa.com"
        }
    }```

b.指定生成的apk文件名。
```buildTypes {
        debug {
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        release {
            minifyEnabled false
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'


            applicationVariants.all { variant ->
                if (variant.buildType.name.equals('release')) {
                    variant.outputs.each { output ->
                        def outputFile = output.outputFile
                        if (outputFile != null && outputFile.name.endsWith('.apk')) {
                            // 输出apk名称为test_v1.0_2015-01-15_wandoujia.apk
                            def fileName = "DM_${variant.productFlavors[0].name}_${defaultConfig.versionName}.apk"
                            output.outputFile = new File(outputFile.parent, fileName)
                        }
                    }
                }
            }
        }
    } ```

c.指定多少种渠道。
productFlavors {
        YstenJS {
            //这是生成正式站、测试站两种app包用的
           /* manifestPlaceholders = [app_name:"xxxx" ,icon: "@mipmap/ic_launcher_xxxx"]
            resValue("string" , "baseUrl","xxxxxxx")
            android:label="${app_name}"
            android:icon="${icon}"
            value=context.getResource().getString(R.string.key)*/
        }
        dangbei {}
        damai {}

        productFlavors.all {
            flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
        }
    }
4.运行:gradle clean 
            gradlew assembleRelease
5.完整的代码。
