[原创]Nexus5 移植OneStep

OneStep 简介 https://github.com/SmartisanTech/android

One Step 涉及的工程列表：

frameworks_base (需要更改WindowManager) https://github.com/SmartisanTech/android_frameworks_base
frameworks_native (需要更改input, 响应调整window后touch事件)https://github.com/SmartisanTech/android_frameworks_native
packages_apps_OneStep(OneStep UI层) https://github.com/SmartisanTech/packages_apps_OneStep
build（加入smartisanos框架编译以及OneStep应用） https://github.com/SmartisanTech/android_build
external_sepolicy (为新引入的OneStepService设置权限)https://github.com/SmartisanTech/android_external_sepolicy
frameworks_smatisanos_base (smartisanos 框架层) https://github.com/SmartisanTech/android_frameworks_smartisanos-base

由于自己已经下载过android的全套源码，移植时采取部分更新的方式进行，具体就是只替换git上 6-7月份之间更新的代码，这部分是onestep改动的地方，其他部分的代码原封不动

替换完直接进行编译,主要遇到只有两个的问题：

1、

搜索build目录下，发现build/core/tasks/check_boot_jars/check_boot_jars.py脚本里CheckJar函数会打印上面的提示

参考https://zhidao.baidu.com/question/1387700248427899620.html，检查移植过程，发现package_whitelist.txt 忘记替换了。

问题2：

报错部分位于：

查找代码，

发现只是实现和调用没有同步更新

新的实现：

移值完成后

近日，重新编译源码，发现突然编译不过去了

网上说法一堆，很多是资源文件没按照规则写导致的，没法解决根本问题

可以看到不合理的地方在已经指定了TARGET_DEVICE 为hammerhead，为什么编译时变成了common

No private recovery resources for TARGET_DEVICE hammerhead

            || exit 31; 
        $(ACP) -fp $$GENERATED_R_FILE $@ || exit 32; 
    done;

报错变成

target R.java/Manifest.java: BasicDreams (out/target/common/obj/APPS/BasicDreams_intermediates/src/R.stamp)
sain begin

#### make failed to build some targets (54 seconds) ####

可见问题出在 $(create-resource-java-files)

这个问题最后也没有解决，删除所有的apps和 framework，重新repo sync也不行（2018年03月11日）

但自己在package新建的app就可以编译通过，是不是support包导致的呢，在ide中曾经也碰到过这种问题
