# APPUtils
|
||||
|
||||
#### 介绍
|
||||
应用开发工具套件类
|
||||
|
||||
#### 软件架构
|
||||
适配安卓应用 [AIDE Pro] 的 Gradle 编译结构。
|
||||
也适配安卓应用 [AndroidIDE] 的 Gradle 编译结构。
|
||||
|
||||
|
||||
#### Gradle 编译说明
|
||||
调试版编译命令 :gradle assembleBetaDebug
|
||||
阶段版编译命令 :git pull && bash .winboll/bashPublishAPKAddTag.sh apputils
|
||||
阶段版类库发布命令 :git pull &&bash .winboll/bashPublishLIBAddTag.sh libapputils
|
||||
|
||||
#### 使用说明
|
||||
|
||||
#### 参与贡献
|
||||
|
||||
1. Fork 本仓库
|
||||
2. 新建 Feat_xxx 分支
|
||||
3. 提交代码 : ZhanGSKen(ZhanGSKen<zhangsken@188.com>)
|
||||
4. 新建 Pull Request
|
||||
|
||||
|
||||
#### 特技
|
||||
|
||||
1. 使用 Readme\_XXX.md 来支持不同的语言,例如 Readme\_en.md, Readme\_zh.md
|
||||
2. Gitee 官方博客 [blog.gitee.com](https://blog.gitee.com)
|
||||
3. 你可以 [https://gitee.com/explore](https://gitee.com/explore) 这个地址来了解 Gitee 上的优秀开源项目
|
||||
4. [GVP](https://gitee.com/gvp) 全称是 Gitee 最有价值开源项目,是综合评定出的优秀开源项目
|
||||
5. Gitee 官方提供的使用手册 [https://gitee.com/help](https://gitee.com/help)
|
||||
6. Gitee 封面人物是一档用来展示 Gitee 会员风采的栏目 [https://gitee.com/gitee-stars/](https://gitee.com/gitee-stars/)
