Flyme patchrom项目笔记
1.官方流程
## 标准流程 ##
下载完代码以后, 在开源项目根目录, 执行以下命令初始化开发环境:
$ source build/envsetup.sh
创建一个新的机型工程的目录(以demo为例), 后续的移植都在机型目录完成。
$ mkdir -p devices/demo
$ cd devices/demo
按照如下步骤，完成一个新机型的适配：
$ flyme config # 生成机型配置文件Makefile
$ flyme newproject # 生成新机型目录
$ flyme patchall # 自动插桩
$ flyme fullota # 生成适配完成的ROM包
## 冲突处理 ##
自动插桩可能会造成代码合并冲突。冲突会以下面的形式标注出来, 开发者需要在厂商的文件中手工解决这些冲突。
<<<<<<< VENDOR
原厂的代码块
=======
Flyme的代码块
>>>>>>> BOSP
## 版本升级 ##
可以跟随官方发布的最新ROM包，将已经是适配完成的机型升级到最新版本：
$ flyme cleanall
$ flyme upgrade
2.个人总结流程及注意事项
- 连接手机，打开usb调试，运行flyme config，生成makefile，关于makefile配置

include $(PORT_BUILD)/main.mk2.完成Makefile配置后，将机型的boot.img和recovery.img放入机型目录，然后执行flyme patchall
3.将base_cm目录下的FlymeLauncher、Keyguard、MmsService、SystemUI、Telecom、TeleService、overlay、custom_app.sh、custom_jar.sh文件夹和文件复制到机型目录，然后进行手动patch
4.手动patch完成后，运行flyme fullota进行打包，完成后删除刷机脚本的机型验证方可刷入
5.刷入后，运行adb logcat >1.txt进行log分析
6.打包时遇到问题：

很多开发者之前遇到过framework.jar的函数超过限制，需要拆分，所以在Android 5.0以下的版本，会有诸如framework2.jar, framework-ext.jar, secondary-framework.jar这样的framework拆分包。但Android 5.0不再拆分jar包，而是直接拆分dex包，所以在framework.jar包中，会包含 classes.dex和classes2.dex这两个dex包，同样是为了解决函数超过限制的问题。
当其中某一个dex包的函数数量超过限制，在做apktool重编译时，就会出现如上错误。只需要将部分文件挪到另一个dex包中便可解决这个报错。
