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：
同一个项目
不同的apk图标
不同的服务器域名
不同的包名
不同的名称
不同的签名
不同的第三方key
不同的版本名版本号
解决思路
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。
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）
相信还有其他的。。。
相关的几个要点
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 {}
}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）
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"
}
}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。
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 1
versionName "1.0.0"
signingConfig signingConfigs.userquhuaRelease // 配置签名
String qq_id = '"xxxxxxxxx"' //配置qq appid
buildConfigField "String", "QQ_ID", qq_id
buildConfigField "String", "WX_ID", '"wxxxxxxxxxxxxxxxxx"' // 配置微信appid
manifestPlaceholders = [ 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。
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。
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${applicationId}代替。在打包的时候，会自动替换成当前包名。
比如，类似下配置：
<permission android:name="com.xxx.xx.permission.JPUSH_MESSAGE" android:protectionLevel="signature" /><uses-permission android:name="com.xxx.xx.permission.JPUSH_MESSAGE" /><receiver android:name=".push.MyJPushMessageReceiver" android:enabled="true" android:exported="false" > <intent-filter> <action android:name="cn.jpush.android.intent.RECEIVE_MESSAGE" /> <category android:name="com.xxx.xx" /> </intent-filter></receiver><provider android:name="android.support.v4.content.FileProvider" android:authorities="com.xxx.xx.provider" android:exported="false" tools:replace="android:authorities" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /></provider>
可改为：
<permission
android:name="${applicationId}.permission.JPUSH_MESSAGE"
android:protectionLevel="signature" /><uses-permission android:name="${applicationId}.permission.JPUSH_MESSAGE" /><receiver
android:name=".push.MyJPushMessageReceiver"
android:enabled="true"
android:exported="false" >
<intent-filter>
<action android:name="cn.jpush.android.intent.RECEIVE_MESSAGE" />
<category android:name="${applicationId}" />
</intent-filter></receiver><provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
tools:replace="android:authorities"
android:grantUriPermissions="true">
<meta-data
android: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

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。
