+# 光环助手Android客户端
+
+### APK打包配置
+
+* 使用[ApkChannelPackage](https://github.com/ltlovezh/ApkChannelPackage)的方案
+* 打包命令，视情况使用：
+
+    > 打包Tinker基准包：`./scripts/tinker_release_base.sh`
+
+    > 以Tinker基准包打渠道包：`./scripts/tinker_release_channel.sh`
+
+    > 以Tinker基准包打补丁包：`./scripts/tinker_release_patch.sh`
+
+### 混淆配置
+
+* 配置文件：Android默认配置+proguard-rules.txt等
+* 参考libraries下每个项目独立的配置文件`proguard-project.txt`
+
+### apk大小优化
+
+* 限制resConfig资源集
+* 开启ShrinkResources
+* 开启混淆，使用minifyEnabled(仅在release开启）
+* pngquant对png压缩、png/jpg->webp(未尝试)
+
+### 第三方appkey等配置
+
+* 修改`gradle.properties`文件将各种key填入其中，实现统一管理
+* 通过gradle文件内的resValue/buildConfigField/manifestPlaceHolder方式实现编译期间修改，具体情况请参考``./build.gradle``和``./app/build.gradle``配置
+
+### 拉取代码步骤
+
+1. 拉取主项目代码: `git clone -b dev git@gitlab.ghzhushou.com:halo/assistant-android.git`
+2. 初始化公用类库: `bash ./scripts/submodules_init.sh`
+
+### submodule管理方式(只拉取master)
+
+* 提交代码，需要cd到submodule文件夹去做修改
+* 更新远端代码，`bash ./scripts/submodules_update.sh`
+
+### TODO
+
+* GSON 序列化用统一的一个, GsonUtil fromJson
+* CleanApkAdapter 转化字符串size工具函数 比如SpeedUtils
+* getString 解决 字符串hardcode问题
+* ~~Adapter 里面clicklistener 用接口传参将点击操作委托给controller~~
+* ~~Adapter ViewHolder的功能，部分重写到ViewHolder类本身~~
+
+* ~~activity 统一入口未完成(外部入口相关)，去除多余activity使用，统一toolbar~~
+* ~~release / debug compile不同的类库，不需要再做什么开关~~
+
+* ~~Toolbar分离，有图形按钮/没有图形按钮~~
+
+### TODO Since 3.1
+
+- 解决 Utils 工具类引发的内存泄漏问题
+- 把原有 EventBus 的消息 Type 统一到一个文件内
+- 将实现细节从 View(Fragment、Activity) 剥离并以 MVVM 结构改造
+- ~~将 ListViewModel 所对应的 ListRepository 合并到 ListViewModel 中~~
+- 依照光环助手界面功能以大模块 - 小模块的方式去修改包结构，包内文件建议以包名摘要作为前缀
+- ~~使用 RxJava 的 Debounce 和 Map 操作优化搜索触发机制 参考资料:[1](https://proandroiddev.com/building-an-autocompleting-edittext-using-rxjava-f69c5c3f5a40),[2](https://medium.com/@kurtisnusbaum/rxandroid-basics-part-2-6e877af352)~~
+
+- ~~把 ListViewModel 的数据结构类型转换方式换为抽象方法，让继承的类实现，避免出现无响应的问题~~
+
+- ~~rxjava2 如果接口返回为空 会发生异常:java.lang.NullPointerException: Null is not a valid element (答案编辑) 解决方法->com.gh.gamecenter.retrofit.Response~~
+- constraintLayout 1.1.2 导致布局出现异常(问题编辑标签选择弹窗)
+
+- 搞清楚 GameManager 的用途，看能不能去掉
+- 重构一下 MainActivity

-    	是必须的，其中的AppKey是您在ShareSDK上注册的开发者帐号的AppKey
-    	
-    	2、所有集成到您项目的平台都应该为其在表格中填写相对应的开发者信息，以新浪微博为例：

-    	其中的SortId是此平台在分享列表中的位置，由开发者自行定义，可以是任何整型数字，数值越大
-    	越靠后AppKey、AppSecret和RedirectUrl是您在新浪微博上注册开发者信息和应用后得到的信息
-    	Id是一个保留的识别符，整型，ShareSDK不使用此字段，供您在自己的项目中当作平台的识别符。
-    	Enable字段表示此平台是否有效，布尔值，默认为true，如果Enable为false，即便平台的jar包
-    	已经添加到应用中，平台实例依然不可获取。

-/**
- * Helper class that can enqueue and process adapter update operations.
- * <p>
- * To support animations, RecyclerView presents an older version the Adapter to best represent
- * previous state of the layout. Sometimes, this is not trivial when items are removed that were
- * not laid out, in which case, RecyclerView has no way of providing that item's view for
- * animations.
- * <p>
- * AdapterHelper creates an UpdateOp for each adapter data change then pre-processes them. During
- * pre processing, AdapterHelper finds out which UpdateOps can be deferred to second layout pass
- * and which cannot. For the UpdateOps that cannot be deferred, AdapterHelper will change them
- * according to previously deferred operation and dispatch them before the first layout pass. It
- * also takes care of updating deferred UpdateOps since order of operations is changed by this
- * process.
- * <p>
- * Although operations may be forwarded to LayoutManager in different orders, resulting data set
- * is guaranteed to be the consistent.
