+#### 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
+```
+
+```

+
+#### 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

+  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
