+#### springboot 下 java 调用 apktool
++ 从官网下apktool.jar
++ 把依赖加入gradle 
+dependencies 下添加
+```
+compile files('tool/apktool.jar')
+```
+但是apktool和springboot 里面的依赖冲突了 报 **java.lang.NoSuchMethodError**
+从报错种找到相关包:
+
++ org.yaml.snakeyaml
+springboot 下是1.25
+apktool 下是 1.12
+好吧
++ 要么编译springboot 要么编译 apktool 
++ 本着新版本应该会向老版本兼容的原则 尝试把 apktool 的 snakeyaml 从1.12提升到1.25
+#### 编译 apktool 
++ github 下载源码
+参考编译说明:
+https://ibotpeaches.github.io/Apktool/build/
++ 修改 build.gradle  Line:122 切换版本
+```
+snakeyaml: 'org.yaml:snakeyaml:1.12:android',
+修改为
+snakeyaml: 'org.yaml:snakeyaml:1.25:android',
+```
++ gradlew.bat 秒闪后退出 看不清报错信息
+修改gradlew.bat  在 :execute 后加 pause 看报错信息
+```
+:execute
+@rem Setup the command line
+
+set CLASSPATH=%APP_HOME%\gradle\wrapper\gradle-wrapper.jar
+
+@rem Execute Gradle
+"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" -classpath "%CLASSPATH%" org.gradle.wrapper.GradleWrapperMain %CMD_LINE_ARGS%
+pause
+```
++ 看到原因 Unsupported class file major version 57
+  好吧 jdk13 不支持 换jdk 8 
+  重新编译成功
+
++ 文件在: **brut.apktool/apktool-cli**, 没看到这句话 纠结了1kb好久
+```
+After build completes you should have a jar file at: ./brut.apktool/apktool-cli/build/libs/apktool-xxxxx.jar
+```
+
+```

+# build Apk with html
+[中文点这里](README_zh.md)
+#### Start
++ build Apk with html, which can be local(index_html) or network(http)
++ Using HTML as UI, can be used as server or local 
++ Three ways to local_html: sinlge-file, zip or  folders(only support chrome)
+
+#### require
++ java 1.8+
+
+#### theory
++ Decompilation through apktool[^1]
++ Modify decompiled content
++ Recompile and sign
+[^1]: 1 apktool.jar -> org.yaml.snakeyaml and springboot Version conflict (springboot snakeyaml-1.25, apktool snakeyaml-1.12) Must compile by yourself See [How to Build ApkToolJar](HowtoBuildApkToolJar.md)
+
+#### todo
++ Support for multi-user simultaneous use
++ UI adjustment
++ Support package name modification
++ Support version modification
++ More about WebView features
+  - Navigation bar
+  - progress bar
+  - etc..
+  
+#### How to use
++ Installing the Java environment 1.8 +
++ download releases 
++ java -jar html2apk-1.0.jar
++ defaul port 80, if u wana modify port:
+  java -jar demo.jar --server.port=8080
++ you must have apk-template dir : /apk/*   
++ you must have ui dir : /html/*   
+
+####  How to Build
++ ./gradlew for unix based systems or gradlew.bat for windows.
++ After build completes you should have a jar file at: build/libs/html2apk-xxx.jar

+# html 生成 Apk
+#### 简介
+
++ 使用一个本地/网络的网页, 生成一个apk
+
++ 使用html作为UI, 可以做服务器使用, 也可以在本地使用
+
++ 支持使用单index.html 压缩包 和 文件夹(仅支持chrome) 3种方式
+
+#### 需要环境
+java 1.8+
+
+#### 原理
+
++ 通过apktool[^1]反编译
++ 修改反编译后的内容
++ 重新编译并签名
+
+[^1]: 1 apktool.jar 由于 org.yaml.snakeyaml 和springboot 下的版本冲突(springboot 下是1.25 apktool 下是 1.12) 必须自己编译 详见 [如何编译apktool.jar](HowtoBuildApkToolJar.md)
+
+#### todo
++ 多用户同时使用的支持
++ UI 调整
++ 支持包名的修改
++ 支持版本号修改
++ 更多关于webview的功能
+  - 导航条
+  - 进度条
+  - 其他的东西
+#### 如何使用
++ 安装java 环境1.8 +
++ 下载realse 
++ java -jar html2apk-1.0.jar
++ 默认80 如果你想修改端口:
+  java -jar demo.jar --server.port=8080
++ 需包含 apk 的模板文件夹 apk  
++ 需包含 前端UI文件夹 html  
+####  如何编译 How to Build
++ ./gradlew for unix based systems or gradlew.bat for windows.
++ After build completes you should have a jar file at: build/libs/html2apk-xxx.jar
