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

2.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：

    I: Using Apktool 2.0.0-RC4I: Checking whether sources has changed...I: Smaling smali folder into classes.dex...Exception in thread "main" org.jf.util.ExceptionWithContext: Unsigned short value out of range: 71412at org.jf.dexlib2.writer.DexDataWriter.writeUshort(DexDataWriter.java:116)at org.jf.dexlib2.writer.InstructionWriter.write(InstructionWriter.java:312)at org.jf.dexlib2.writer.DexWriter.writeCodeItem(DexWriter.java:990)at org.jf.dexlib2.writer.DexWriter.writeDebugAndCodeItems(DexWriter.java:769)at org.jf.dexlib2.writer.DexWriter.writeTo(DexWriter.java:222)at org.jf.dexlib2.writer.DexWriter.writeTo(DexWriter.java:200)at brut.androlib.src.SmaliBuilder.build(SmaliBuilder.java:57)at brut.androlib.src.SmaliBuilder.build(SmaliBuilder.java:41)at brut.androlib.Androlib.buildSourcesSmali(Androlib.java:354)at brut.androlib.Androlib.buildSources(Androlib.java:294)at brut.androlib.Androlib.build(Androlib.java:280)at brut.androlib.Androlib.build(Androlib.java:255)at brut.apktool.Main.cmdBuild(Main.java:225)at brut.apktool.Main.main(Main.java:84)

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。
