-### ☁ 看远方 ☁ ###
-### ☁ 心忧虑 ☁ WinBoLL-APP 应用前置需求
-☁ WinBoLL-APP WinBoLL 项目根目录设定为手机的 /sdcard/WinBoLLStudio/Sources 目录。（需要用户手动建立文件夹）

+## 三、应用编译环境检查问题
+### 核心判断条件：
+☆ WinBoLL 项目以文件夹 `"/sdcard/WinBoLLStudio/APKs"` 是否存在为判断环境编译输出条件，因为编译输出的APK文件需要一个可供保存的环境。
 
-### ☁ 云游四方 ☁ ###
-### ☁ 呔！ ☁ WinBoLL-APP 应用需求规划
-☁ 如要使用 WinBoLL Android 项目的 Gradle 编译功能，则需要设置以下两个文件夹。
-☁ 1. 则需要建立数据存储目录 /sdcard/WinBoLLStudio/APKs。
-   WinBoLL 项目源码编译出来的安装包会拷贝一份到 /sdcard/WinBoLLStudio/APKs 目录下。 
-☁ 2. 则需要建立数据存储目录 /sdcard/AppProjects。
-   WinBoLL 项目源码编译出来的安装包会拷贝一份并命名 "app.apk" 的安装文件为到 /sdcard/AppProjects 目录下。 
+☆ 文件夹"/sdcard/WinBoLLStudio/APKs" 目录条件设置方法：
+***Linux 服务器端方面***：建立 `/sdcard/WinBoLLStudio/APKs` 目录即可。
+***手机开发端方面***：建立 `"/sdcard/WinBoLLStudio/APKs"` 目录(即 `"/storage/emulated/0/WinBoLLStudio/APKs"` 目录) 即可。
 
+## 四、前置条件
 
-### ☁ 吁！ ☁ WinBoLL-APP 共享计划前景
-☁ WinBoLL-APP 将会实现 https://winboll.cc/api 访问功能。
-☁ WinBoLL-APP 将会实现手机端 Android 应用的开发与管理功能。
+### 1. WinBoLL APP 开发环境配置介绍
+####  WinBoLL APK 编译输出内容包括：
+☆ "/sdcard/WinBoLLStudio/APKs"` 目录内的所有应用分支的 APK 文件。
+☆ "/sdcard/AppProjects/app.apk"文件。
+#### WinBoLL APK 源码命名空间规范
+☆ WinBoLL 项目使用 "cc.winboll.studio" 作为源码命名空间。在此命名空间下进行源码定义。
 
-## ☁ WinBoLL ☁ WinBoLL 主机忧虑
-☁ WinBoLL 将会提供 gitea.winboll.cc 域名用户注册登录功能。
-☁ WinBoLL 将会提供 WinBoLL-APP 及其衍生应用的 Gitea 仓库管理服务。
-☁ WinBoLL 将会提供 winboll.cc 域名 WinBoLL 项目组注册登录功能。
+## 五、核心需求规划
 
-# 本项目要实际运用需要注意以下几个步骤：
-# 在项目根目录下：
-## ★. 项目模块编译环境设置(必须)，settings.gradle-demo 要复制为 settings.gradle，并取消相应项目模块的注释。
-## ★. 项目模块编译环境设置(必须) 在根目录拷贝 gradle.properties-androidx-demo 或者 gradle.properties-android-demo 文件为 gradle.properties。
-## ★. 项目 Android SDK 编译环境设置(可选)，local.properties-demo 要复制为 local.properties，并按需要设置 Android SDK 目录。
-## ★. 应用签名密钥 keystore 设置问题。一般调试编译只需用【Termux】cd 进 GenKeyStore 目录执行 $ bash gen_debug_keystore.sh 命令即可完成设置。
-## ☆. 应用 WiBoLL 签名密钥配置问题<非必须考虑>。设置时需要 clone 【keystore】模块源码并拷贝模块目录的 appkey.jks 与 appkey.keystore 到项目根目录即可。
-## ☆. 类库型模块编译环境设置(可选)，winboll.properties-demo 要复制为 winboll.properties，并按需要设置 WinBoLL Maven 库登录用户信息， 和 APK 文件额外输出路径。
+### 1. WinBoLL 应用安全验证需求
+#### ☆ 支持访问 https://console.winboll.cc/ 服务器以校验应用包签名与版本。
 
+### 2. 手机端源码开发管理需求
+#### ☆ 支持切换不同 WinBoLL 分支，以开发不同安卓应用。
 
-# ☆类库型项目编译方法
-## 先编译类库对应的模块测试项目
-### 修改模块测试项目的 build.properties 文件
-设置属性 libraryProject=<类库项目模块文件夹名称>
-### 再编译测试项目
-$ bash .winboll/bashPublishAPKAddTag.sh <应用项目模块文件夹名称>
-#### 测试项目编译后，编译器会复制一份 APK 到 路径："/sdcard/WinBoLLStudio/APKs/<项目根目录名称>/tag/" 文件夹。
-#### 若是 winboll.properties 文件的 [ExtraAPKOutputPath] 属性设置了路径。编译器也会复制一份 APK 到这个路径。
-### 最后编译类库项目
-$ bash .winboll/bashPublishLIBAddTag.sh <类库项目模块文件夹名称>
-#### 类库模块编译命令执行后，编译器会发布到 WinBoLL Nexus Maven 库：Maven 库地址可以参阅根项目目录配置 build.gradle 文件。
-             
-# ☆应用型项目编译方法
-## 直接调用以下命令编译应用型项目
-$ bash .winboll/bashPublishAPKAddTag.sh <应用项目模块文件夹名称>
-#### 应用模块编译命令执行后，编译器会复制一份 APK 到
-#### 测试项目编译后，编译器会复制一份 APK 到 路径："/sdcard/WinBoLLStudio/APKs/<项目根目录名称>/tag/" 文件夹。
-#### 若是 winboll.properties 文件的 [ExtraAPKOutputPath] 属性设置了路径。编译器也会复制一份 APK 到这个路径。
+## 六、编译与使用指南
 
-## ☆应用调试编译方法
-使用以下命令编译调试：
+### 1. 项目初始化（必须）
+#### 1.  复制 `settings.gradle-demo` 为 `settings.gradle`。编辑 `settings.gradle` 文件内容，取消对应项目模块注释。
+#### 2.  复制 `gradle.properties-androidx-demo` (Android X 项目) 或 `gradle.properties-android-demo` (基本 Android 项目) 为 `gradle.properties`。
+#### 3.  复制（可选）`local.properties-demo` 为 `local.properties`，编辑 `local.properties` 文件内容，配置 Android SDK 目录。
+#### 4.  **签名设置**：
+    ☆ **调试编译秘钥制作**：使用 Termux 应用终端，cd 进入 GenKeyStore 目录，运行 `bash gen_debug_keystore.sh` 脚本即可生成应用调试秘钥。
+    ☆  **应用秘钥配置方法**：拷贝调试编译秘钥制作生成的 `appkey.jks` 与 `appkey.keystore` 文件到项目根目录即可。
 
-### Beta调试使用：
-$ bash gradlew assembleBetaDebug
+## 七、应用编译命令介绍
 
-### Stage调试使用：
-$ bash gradlew assembleStageDebug
+### （1）类库型模块配置要点
+#### 1.  **优先修改配置文件**：优先修改应用测试项目（目录为 `"<WinBoLl根目录>/<类库测试应用>/"`）内 `build.properties` 文件，设置对应的类库项目名称：`libraryProject=<类库项目模块名>`。
+#### 2.  **编译优先启动步骤**：使用 Termux 应用，进入 `"<WinBoLl根目录>"`，运行 `$ bash .winboll/bashPublishAPKAddTag.sh <类库测试项目模块名>` 命令。运行后可生成测试项目与类库项目的编译参数文件 `build.properties`。生成的 `build.properties` 文件有两份，一份在测试项目模块的文件夹内，一份在类库项目本身的模块文件夹内。
+#### 3.  **最后类库编译发布步骤**：使用 Termux 应用，进入 `"<WinBoLl根目录>"`，运行 `$ bash .winboll/bashPublishLIBAddTag.sh <类库项目模块名>` 命令。运行后可发布至 WinBoLL Nexus Maven 库、本地 maven 目录或者是通用默认的 Gradle Maven 库。
 
-### 若是 winboll.properties 文件的 [ExtraAPKOutputPath] 属性设置了路径。编译器也会复制一份 APK 到这个路径。
+### （2）单一应用型模块与类库测试型模块配置要点
+#### ☆ APK 编译方法：
+使用 Termux 应用，进入 `"<WinBoLl根目录>"`，运行 `$ bash .winboll/bashPublishAPKAddTag.sh <应用项目模块名>`。
+#### ☆ 运行后的 APK 输出路径：
+★ 默认路径 (`$ bash gradlew assembleBetaDebug` 任务)：APK 在 `/sdcard/WinBoLLStudio/APKs/<项目根目录名称>/debug/` 目录。
+★ 默认路径 (`$ bash assembleStageRelease` 任务)：APK 在 `/sdcard/WinBoLLStudio/APKs/<项目根目录名称>/tag/` 目录。
+★ 额外输出路径：(假设 `winboll.properties` 文件已配置 `ExtraAPKOutputPath` 属性) 输出至 `ExtraAPKOutputPath` 属性配置的目录下。
 
-# 应用版本号命名方式
-## statge 渠道

-## beta 渠道
-V<应用开发环境编号><应用功能变更号><应用调试阶段号>-beta<调试编译计数>_<调试编译时间(分钟+秒钟)>
-如：APPBase_15.9.6-beta8_5413
+### （3）手机端应用调试命令介绍
+#### ☆ Beta 渠道调试命令
+$bash gradlew assembleBetaDebug
+
+#### ☆ Stage 渠道调试命令
+$bash gradlew assembleStageDebug
+
+### （4）服务器端开发命令介绍
+##### ☆ Stage 渠道应用发布命令为：
+（"<WinBoLl根目录>/settings.gradle"文件需要配置编译模块开启参数，拷贝 settings.gradle-demo 为 settings.gradle 文件取消对应的分支配置部分即可。）
+$bash .winboll/bashPublishAPKAddTag.sh <应用项目模块名> 
+或者是
+$bash gradlew assembleStageRelease
+ 
+
+## 八、WinBoLL 应用 APK 版本号命名规则
+### ☆ Stage 渠道：
+#### V<应用开发环境编号><应用功能变更号><应用调试阶段号> （示例： APPBase_15.7.0 ）
+### ☆ Beta 渠道：
+#### V<应用开发环境编号><应用功能变更号><应用调试阶段号>-beta<调试编译计数>_<调试编译时间(分钟+秒钟)> （示例： APPBase_15.9.6-beta8_5413 ）
