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="${jush_appkey_value}" />
<meta-data
android:name="SHOUCANG_CONFIG0"
android:value="${SHOUCANG_CONFIG_VALUE0}" /> build.gradle:
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-android.txt'), '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-android.txt'), 'proguard-rules.pro'
//是否zip优化
zipAlignEnabled true
//删除一些无用资源
shrinkResources false
//
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:
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
def demo = '0000';//DemoAPK
def demo1 = '0001';//DemoAPK1
def demo2 = '0002';//DemoAPK2
def demo3 = '0003';//DemoAPK3
def demo4 = '0004';//DemoAPK4
def demo5 = '0005';//DemoAPK5
def demo6 = '0006';//DemoAPK6
android {
signingConfigs {
debug {
keyAlias '****'
keyPassword '****'
storeFile file('签名文件.jks路径')
storePassword '****'
}
release {
keyAlias '****'
keyPassword '****'
storeFile file('签名文件.jks路径')
storePassword '****'
}
}

} 接着就是多版本的代码判断书写：
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
//TODO 多版本切换 写此方法bufen
which_version();
// ShoucangConfig0.config();//manifestPlaceholders的妙用
super.onCreate(savedInstanceState);
}
private void which_version() {
if (ConstantNetUtil.VERSION_APK == NetConfig.version_name0) {
ShoucangConfig.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name1) {
ShoucangConfig1.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name2) {
ShoucangConfig2.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name3) {
ShoucangConfig3.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name4) {
ShoucangConfig4.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name5) {
ShoucangConfig5.config();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name6) {
ShoucangConfig6.config();
}
}
//TODO 多版本模式bufen
SparseArrayCompat<Class<? extends BaseFragment>> array = which_version_fragment_config();//demo
private SparseArrayCompat<Class<? extends BaseFragment>> which_version_fragment_config() {
if (ConstantNetUtil.VERSION_APK == NetConfig.version_name0) {
return ShoucangConfig.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name1) {
return ShoucangConfig1.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name2) {
return ShoucangConfig2.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name3) {
return ShoucangConfig3.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name4) {
return ShoucangConfig4.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name5) {
return ShoucangConfig5.getFragments();
} else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name6) {
return ShoucangConfig6.getFragments();
}
return ShoucangConfig.getFragments();
} 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~
