最近在学习撸撸的代码规范和写法，有些心得，准备好好写一写~包括了多渠道打版（以前有写过方法），工厂模式，mvp，以及最近刚封装出来的多渠道多版本展示不同页面的manifestPlaceholders的配置方法，大家应该也碰到过线上和线下环境的切换换地址，换私钥的头大问题，本篇就来解决这些问题。
先在androidmanifest文件配置一个节点，这里以极光为例：

<meta-data
android:name=
"JPUSH_APPKEY"
android:value=

/>
<meta-data
android:name=
"SHOUCANG_CONFIG0"
android:value=
"${SHOUCANG_CONFIG_VALUE0}"
/>

buildTypes {
release {
//自定义buildconfig字段
buildConfigField(
"boolean"
,
"APP_ENV"
,
"true"
)
//指定签名为release
signingConfig signingConfig.release
//是否开启混淆
minifyEnabled
false
proguardFiles getDefaultProguardFile(

),
'proguard-rules.pro'
//是否zip优化
zipAlignEnabled
true
//删除一些无用资源
shrinkResources
false
//
manifestPlaceholders = [
"jush_appkey_value"
:
"release key"
]
}
debug {
//自定义buildconfig字段
buildConfigField(
"boolean"
,
"APP_ENV"
,
"true"
)
//指定签名为release
signingConfig signingConfig.release
//是否开启混淆
minifyEnabled
false
proguardFiles getDefaultProguardFile(

),
'proguard-rules.pro'
//是否zip优化

//删除一些无用资源

//
manifestPlaceholders = [
"jush_appkey_value"
:
"debug key"
]
}
}

在bulidtypes节点下有release节点和debug节点，正式签名时就会走release节点的下编译脚本，调试签名时就会走debug节点。主要点就是manifestPlaceholders的用法，jpush_appkey对应的就是之前在androidmanifest文件配置的${jush_appkey_value}的这个值。
在程序入口出打上log，用来输出key的值:

/**
* 在程序入口出打上log，用来输出key的值bufen
*/
private
void
jpush_key_manifest_xml_string() {
String jpush_appkey;
try
{
ApplicationInfo appInfo = getPackageManager()
.getApplicationInfo(getPackageName(),
PackageManager.GET_META_DATA);
jpush_appkey = appInfo.metaData.getString(
"JPUSH_APPKEY"
);
Log.e(
"jpush_appkey"
,
"jpush_appkey="
+ jpush_appkey);
}
catch
(PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}

接下来给大家介绍多版本多页面多apk的配置切换方法：举个例子：如果你要一次性打七个版本，而且七个版本都是不同的页面，但是页面各个模块大体一样，只是顺序和大小不同，你要怎么做，别告诉我写七个页面分别打版哈~太low了~you know~这里就利用多版本打版和manifestPlaceholders来实现需求。
首先是build.gradle:

这样跑完apk你会发现会有神奇的事情发生，如下图：（不同的apk版本出来的页面也是不同的，但是只用了一份代码。）
图1：
图2：
这样做的好处在于，如果你的apk版本很多，需要给很多合作厂商提供定制化页面，就可以用上了~
卧槽，今天喷了好多，希望大家回去自己细化一下，能帮到你~
