简介

如题所示！本篇文章就是为了解决这种问题。方便打包和运行的时候能做到无需手动替换配置，即可打包想要的apk。打包的时候，只需选一下想打哪种配置的apk就OK啦。 (^o^)/~

先来看，有需求如下：

1. 同一个项目
2. 不同的apk图标
3. 不同的服务器域名
4. 不同的包名
5. 不同的名称
6. 不同的签名
7. 不同的第三方key
8. 不同的版本名版本号

解决思路

1. 当然最直接的方式不过于每次打不同包的时候都去替换对应的配置，这种方式的麻烦之处不言而喻。
2. 将所有配置，资源等都配置入项目中，打包的时候，根据选择渠道打包不同配置的apk。（本篇文章就是要讲怎么这么做的）
3. 相信还有其他的。。。

相关的几个要点

1. 首先我们需要知道productFlavors来配置渠道，这里我将渠道用来表示哪种apk，如下我需要配置四种应用:

productFlavors {userquhua {}quhua {}cuntuba {}xemh {}
}

1. 如果我们选择了某一个渠道，那么运行打包的时候会根据渠道名选择资源文件（可结合第6点一起看）
   
2. 签名可在signingConfigs中配置多个（我将所有签名文件放在了项目跟目录的key文件夹中），这样我们就可以通过signingConfigs指定预制好的签名配置。

signingConfigs {userquhuaRelease {storeFile file("../key/xxx1.keystore")storePassword "xxxxxx"keyAlias "alias"keyPassword "xxxxxx"}quhuaRelease {storeFile file("../key/xxx2.keystore")storePassword "xxxxxx"keyAlias "alias"keyPassword "xxxxxx"}cuntubaRelease {storeFile file("../key/xxx3.keystore")storePassword "xxxxxx"keyAlias "alias"keyPassword "xxxxxx"}xemhRelease {storeFile file("../key/xxx4.keystore")storePassword "xxxxxx"keyAlias "alias"keyPassword "xxxxxx"}
}

1. 可在build.gradle中配置动态配置java代码调用的常量数据（如：通过该方式我们可根据不同渠道动态配置第三方appid，或其他需要根据渠道而改变的数据）

• 比如：我们在defaultConfig {} 中定义了:

buildConfigField "String", "SERVER_URL", '"http://xx.xxxx.com/"'

• 此时，您看一下清单文件中manifest标签里的，package的值，假如是：

com.xxx.xx

• 那么，您就可以在java代码中通过导入文件：

import com.xxx.xx.BuildConfig;

• 然后调用

BuildConfig.SERVER_URL

它的值就是上边配置的字符串：http://xx.xxxx.com/。

• 您可以进入BuildConfig看一看，里面还包含了一些当前的包名版本号等信息。
  

1. 在渠道配置那里可以配置对应的包名版本名签名等等
   如下所示：

// 省略其他配置...
android {// 省略其他配置...productFlavors {userquhua {applicationId "com.xxx.xx"versionCode 1versionName "1.0.0"signingConfig signingConfigs.userquhuaRelease // 配置签名String qq_id = '"xxxxxxxxx"' //配置qq appidbuildConfigField "String",           "QQ_ID", qq_idbuildConfigField "String",           "WX_ID", '"wxxxxxxxxxxxxxxxxx"' // 配置微信appidmanifestPlaceholders = [qq_id: qq_id,JPUSH_PKGNAME : applicationId,JPUSH_APPKEY : "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx", //JPush 上注册的包名对应的 Appkey.JPUSH_CHANNEL : "developer-default",]}}buildTypes {release {// 省略其他配置...signingConfig null  // 置空}debug {// 省略其他配置...signingConfig null // 置空}}
}

• 这样，如果我们打包userquhua这个渠道，看第2点中介绍选择userquhuaDebug。
• 然后，最好clean一下项目、然后我们运行项目。
• 该app的包名就是com.xxx.xx，版本号为1，版本名为1.0.0。
• 通过BuildConfig调用QQ_ID静态常量，就是该渠道里配置的值，WX_ID同理。
• manifestPlaceholders配置也可以这样配置。
• 签名问题经过个人反复尝试（然后半天就过去了￣へ￣），最终签名如上配置。需要注意buildTypes中的签名配置signingConfig如果不设置为null，那么打包的是有还是以内置的签名打包。

1. 资源文件替换
   再看到第2点的介绍，我们选择运行渠道后，会默认匹配对应渠道下的资源。下面我将xemh渠道的资源目录全部展开一下。
   

• 如上图这样，只需要资源名字和app目录对应的文件名字一样即可替换。
• strings.xml里的应用名，只需要将对应app_name修改既可替换app下strings的app_name，其他不用替换的不用写就行。

1. 打正式包的时候选好渠道，就可以打包不同配置的apk，当然您也可以使用命令的方式。
   

其他配置记录

获取当前时间

static def releaseTime() {return new Date().format("yyyy-MM-dd-HH.mm", TimeZone.getTimeZone("GMT+8"))
}

打包的时候，修改文件名，以方便区别渠道和版本打包时间

applicationVariants.all {variant ->variant.outputs.all {outputFileName = "${variant.productFlavors[0].name}-v${variant.productFlavors[0].versionName}-${releaseTime()}.apk"}
}

• ${variant.productFlavors[0].name}当前渠道名
• ${variant.productFlavors[0].versionName}当前版本名
• ${releaseTime()}当前时间

其他需要注意事项

如果您在清单文件AndroidManifest.xml中，有那种以包名开头命名的那种。因为如果包名都改了，有些也需要动态的改变。可以用${applicationId}代替。在打包的时候，会自动替换成当前包名。

比如，类似下配置：

<permissionandroid:name="com.xxx.xx.permission.JPUSH_MESSAGE"android:protectionLevel="signature" />
<uses-permission android:name="com.xxx.xx.permission.JPUSH_MESSAGE" />
<receiverandroid:name=".push.MyJPushMessageReceiver"android:enabled="true"android:exported="false" ><intent-filter><action android:name="cn.jpush.android.intent.RECEIVE_MESSAGE" /><category android:name="com.xxx.xx" /></intent-filter>
</receiver>
<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="com.xxx.xx.provider"android:exported="false"tools:replace="android:authorities"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" />
</provider>

可改为：

<permissionandroid:name="${applicationId}.permission.JPUSH_MESSAGE"android:protectionLevel="signature" />
<uses-permission android:name="${applicationId}.permission.JPUSH_MESSAGE" />
<receiverandroid:name=".push.MyJPushMessageReceiver"android:enabled="true"android:exported="false" ><intent-filter><action android:name="cn.jpush.android.intent.RECEIVE_MESSAGE" /><category android:name="${applicationId}" /></intent-filter>
</receiver>
<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="${applicationId}.provider"android:exported="false"tools:replace="android:authorities"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" />
</provider>

当然值得注意的是，在代码中我们也不能把包名写死了，可通过BuildConfig得到当前包名

结束

就这样就可以解放大量劳动力啦！每次项目打包各种软件，选一下就ojbk，哈哈哈~
如果有些配置在其他渠道没有的，也可通过BuildConfig在java中判断如果是某某渠道那么屏蔽。
