項目切換到Android Studio有一段時間了，來聊聊多渠道打包的做法。

1.在productFlavors添加你需要的所有渠道

android {

    productFlavors {  //在這裏添加你所有需要打包的渠道
        dev {}
        google {}
        myapp {}
        xiaomi {}
        app360 {}
        wandoujia {}
    }
    //添加如下代碼
    productFlavors.all { flavors->
    flavors.manifestPlaceholders=[CHANNEL_VALUE:name]
    }
}

同時修改androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="cn.op.zdf"
    android:versionCode="25"
    android:versionName="3.1.2">
    <application 
        android:name=".myApplication">
        <-- 在manifest中添加如下代碼--->
        <meta-data
                    android:name="UMENG_CHANNEL"
                    android:value="${CHANNEL_VALUE}"/>
    </application>
</manifest>

OK，在命令行運行gradle build，大功告成。你可以去喝杯茶了。

2.如何給apk重命名
恩，發佈產品的時候我們需要如下的命名規則
release版本的命名規則如下：
產品名稱-版本號-渠道號-sign-42.apk

在build.gradle中添加如下代碼
//獲取時間戳

def getDate() {
    def date = new Date()
    def formattedDate = date.format('yyyyMMddHHmm')
    return formattedDate
}
//從androidManifest.xml中獲取版本號
def getVersionNameFromManifest(){
    def manifestParser = new com.android.builder.core.DefaultManifestParser()
    return manifestParser.getVersionName(android.sourceSets.main.manifest.srcFile)
}
android{
    //修改生成的apk名字
    applicationVariants.all{ variant->
        variant.outputs.each { output->
            def oldFile = output.outputFile
            def newName = '';
            if(variant.buildType.name.equals('release')){
//                println(variant.productFlavors[0].name)
                def releaseApkName = 'yjf-android-v' + getVersionNameFromManifest() + '-' + variant.productFlavors[0].name + '-sign-42.apk'
                output.outputFile = new File(oldFile.parent, releaseApkName)
            }
            if(variant.buildType.name.equals('beta')){
                newName = oldFile.name.replace(".apk", "-v" + getVersionNameFromManifest() + "-build" + getDate() + ".apk")
                output.outputFile = new File(oldFile.parent, newName)
            }
            if(variant.buildType.name.equals('debug')){
            }
        }
    }
}

哦，怎麼取得版本號？怎麼取得渠道號？怎麼判斷是不是release版本？上面的代碼裏面都有。
我的項目是從eclipse中遷移過來的，所以我是從manifest文件中讀取的版本號，就是上面的那個函數 getVersionNameFromManifest()
如果你的版本號定義在build.gradle中，那defaultConfig.versionName就是你的版本號。
