菜鸟级别的程序媛，首次做多渠道打包，也是查了一些资料，希望可以帮到你们。

因项目需求，需要给定制客户在原有基础上出一个APP,只更换APP的icon和name。同时项目也有少量部分需要修改的地方，为了更好的迭代开发，Gradle的多渠道打包就派上用场了。
先贴一份主Module的build.gradle文件参考
apply plugin: 'com.android.application'
//************************新增***************************
//获取当前的时间
def releaseTime() {
return new Date().format("HHmm")
}
//设置自增长版本号
def getVersionCode() {
def versionFile = file('version.properties')// 读取第一步新建的文件
if (versionFile.canRead()) {// 判断文件读取异常
Properties versionProps = new Properties()
versionProps.load(new FileInputStream(versionFile))
def versionCode = versionProps['VERSION_CODE'].toInteger()// 读取文件里面的版本号
def runTasks = gradle.startParameter.taskNames
if ('assembleRelease' in runTasks) {//仅在assembleRelease任务是增加版本号,其他渠道包在此分别配置
// 版本号自增之后再写入文件（此处是关键，版本号自增+1）
versionProps['VERSION_CODE'] = (++versionCode).toString()
versionProps.store(versionFile.newWriter(), null)
}
return versionCode // 返回自增之后的版本号
} else {
throw new GradleException("Could not find version.properties!")
}
}
def getVersionName() {
def date = new Date()
def versionName = date.format('yyyyMMdd')
return versionName
}
def currentVersionCode = getVersionCode()
def currentVsionName = getVersionName()
android {

下面请跟着我的步骤来
由于andorid对每个app唯一标识是用applicationId来标识的，所以每个渠道的包根据applicationId来区分。
productFlavors {
//********（默认渠道）******
pro {
manifestPlaceholders = [
UMENG_CHANNEL_VALUE: "pro",
app_icon : "@drawable/pro_icon",
app_name : "@string/pro_app_name",
]
}
//********定制的xxx（applicationId不一样）******
dev {
applicationId "com.android.xxx.xxx"
manifestPlaceholders = [
UMENG_CHANNEL_VALUE: "dev",
app_icon : "@drawable/dev_logo",
app_name : "@string/dev_app_name",
]
}
}
记得在AndroidManifest文件的application节点中引用app的icon和name
meta-data节点一定不能少的哦别忘记了。这里的配置是动态改变icon和name
<application···
android:icon="${app_icon}"
android:label="${app_name}"
<meta-data
android:name="CHANNEL_ID"
android:value="${UMENG_CHANNEL_VALUE}" />
接下就是打包app里，我这里做了一个判断，给apk包名命名是debug的还是release的
android.applicationVariants.all {
variant ->
variant.outputs.all {
output ->
def outputFile = output.outputFile
def fileName
if (outputFile != null && outputFile.name.endsWith('.apk')) {
if (variant.buildType.name.equals('release')) {
fileName = "${variant.productFlavors[0].name}_release_${defaultConfig.versionName}_${releaseTime()}.apk"
} else if (variant.buildType.name.equals('debug')) {
fileName = "${variant.productFlavors[0].name}_debug_${defaultConfig.versionName}_${releaseTime()}.apk"
}
outputFileName = fileName
}
}
}
接下来就让我们来看一下打包的效果吧！

另外如果程序里面某些配置需要根据不同的渠道配置，可以获取applicationId,也就是包名。
例如：
