本文主要包含以下内容

一、查看项目所在分支
二、切换到目标分支
三、查看当前所在分支
四、编译android源码
五、source android 编译环境
六、lunch 所需的编译项目
七、单编 模块
八、push 模块 验证修改是否生效

一、查看项目所在分支

git branch -a
表示：查看并列出当前项目所有分支

高通项目举例如下：

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ git branch -a
* linux_android_development
  master
  remotes/origin/a/b_update_linux_android_development
  remotes/origin/head -> origin/master
  ... ...
  remotes/origin/secure_linux_android_development
  remotes/origin/streamlined_code_engineering
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

二、切换到目标分支

git checkout 分支名
表示： 切换到某个分支。

高通项目举例如下：
git checkout linux_android_development

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ git branch -a
* linux_android_development
  master
  remotes/origin/a/b_update_linux_android_development
  remotes/origin/head -> origin/master
  remotes/origin/cts_development_branch
  ... ...
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ git checkout linux_android_development 

三、查看当前所在分支

git branch
表示：查看当前所在分支

高通项目举例如下：

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ git branch 
* linux_android_development
  master
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

四、编译android源码

android 源码编译，每个项目由于脚本各不相同，编译的命令 有时候也会有说差异。

google 官方编译命令如下

1.source ./build/envsetup.sh
2.lunch 项目
3.make -j8

高通项目编译命令 如下:

./buildall_userdebug.sh e5527m all

五、source android 编译环境

首先进入android 源码根目录，执行source ./build/envsetup.sh,
如不source,后续则无法单编模块。

高通项目举例如下：

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ source ./build/envsetup.sh 
including device/generic/car/vendorsetup.sh
including device/generic/mini-emulator-arm64/vendorsetup.sh
including device/generic/mini-emulator-armv7-a-neon/vendorsetup.sh
including device/generic/mini-emulator-x86_64/vendorsetup.sh
including device/generic/mini-emulator-x86/vendorsetup.sh
including device/generic/uml/vendorsetup.sh
including device/google/muskie/vendorsetup.sh
including device/google/taimen/vendorsetup.sh
including device/qcom/common/vendorsetup.sh
including device/qcom/qssi/vendorsetup.sh
including vendor/partner_gms/products/vendorsetup.sh
including vendor/qcom/opensource/core-utils/vendorsetup.sh
including vendor/qcom/proprietary/common/vendorsetup.sh
including vendor/qcom/proprietary/prebuilt_hy11/vendorsetup.sh
created 9 symlinks out of 9 mapped links..
including sdk/bash_completion/adb.bash
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

六、lunch 所需的编译项目

执行 lunch 命令，查看所有 编译项目列表，然后选择 编译项目。
高通项目 举例如下：

1. lunch ,然后选择所需编译分支

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ lunch
you're building on linux
lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_arm64-eng
     3. aosp_mips-eng
     ... ...
     40. msm8937_64-userdebug
     41. msm8937_64-user
     ... ...
     65. taimenb2-userdebug
// 选择要编译的分支名
which would you like? [aosp_arm-eng] msm8937_64-userdebug
device/qcom/msm8937_64/msm8937_64.mk:42: warning: "build with 4.9 kernel"
 ... ...
out_dir=out
============================================
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

2. 直接lunch 分支

比如我们需要编译msm8937_64-userdebug项目，其实我们可以执行最简单的方法,直接lunch这个项目所排列的位置，比如lunch 40

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ lunch 40
device/qcom/msm8937_64/msm8937_64.mk:42: warning: "build with 4.9 kernel"
============================================
platform_version_codename=rel
platform_version=9
target_product=msm8937_64
... ...
host_cross_2nd_arch=x86_64
host_build_type=release
build_id=pkq1.190601.001
out_dir=out
============================================
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

七、单编 模块

我们常用 mmm 以及mm 来及对单模块进行编译。
mmm 与mm 主要区别在于你当前所在的目录位置。
如果当前正在所要编译模块的地方（需要有android.mk文件，才可以进行），请使用 mm，否则使用mmm。

高通项目举例如下：

1. mmm使用举例（此时不在fm 目录）

比如单编fm，不在fm目录下，需要执行mmm vendor/qcom/opensource/commonsys/fm/fmapp2/

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ mmm vendor/qcom/opensource/commonsys/fm/fmapp2/
/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android/vendor/qcom/opensource/commonsys/fm/fmapp2/
restriction checker not present, skipping..
device/qcom/msm8937_64/msm8937_64.mk:42: warning: "build with 4.9 kernel"
============================================
... ...
out_dir=out
============================================
qssi: not enabled for msm8937_64 target as vendor/qcom/proprietary/release/qssi/qssi_enforced_targets_list.txt was not found.
... ...
#### build completed successfully (7 seconds) ####
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ 

2. mm使用举例(在fm 目录下)

比如单编fm，在fm目录下，需要执行mm

wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android$ cd  vendor/qcom/opensource/commonsys/fm/fmapp2/
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android/vendor/qcom/opensource/commonsys/fm/fmapp2$ mm
restriction checker not present, skipping..
device/qcom/msm8937_64/msm8937_64.mk:42: warning: "build with 4.9 kernel"
============================================
platform_version_codename=rel
platform_version=9
... ...
out_dir=out
============================================
qssi: not enabled for msm8937_64 target as vendor/qcom/proprietary/release/qssi/qssi_enforced_targets_list.txt was not found.
ninja: no work to do.
... ...
build/make/core/base_rules.mk:412: warning: ignoring old commands for target `out/target/product/msm8937_64/vendor/lib64/hw/fingerprint.default.so'
ninja: no work to do.
#### build completed successfully (41 seconds) ####
wangjie@wangjie:/wangjie/qualcomm_p/e5527m_msm8917_qm215_r26/la.um.7.6.2/linux/android/vendor/qcom/opensource/commonsys/fm/fmapp2$ 

八、 push 模块 验证修改是否生效

1. 使用debug版本，挂载手机

adb shell getprop ro.build.type 主要用来查看当前使用的版本，调试只能使用debug 版本，user版本无法调试。

高通项目举例如下：

c:\users\administrator>adb shell getprop ro.build.type
userdebug
c:\users\administrator>adb root
c:\users\administrator>adb remount
remount succeeded
c:\users\administrator>

2.将生成的单模块编译的apk 拷贝到桌面并push到手机中

adb push 本地文件 手机目录
adb push主要用来 替换手机中的apk，调试验证单编是否生效。

高通 fm 举例如下：

c:\users\administrator>adb push c:\users\administrator\desktop\fm2.apk /system/app/fm2
c:\users\administrator\desktop\fm2.apk: 1 file pushed. 9.7 mb/s (861880 bytes in 0.085s)
c:\users\administrator>

3. 清除 push apk 的存储数据

adb shell pm clear 包名
用来清除当前包名的数据。
比如：adb shell pm clear com.caf.fmradio

高通 fm apk举例如下：

c:\users\administrator>adb shell dumpsys activity | findstr run
    running activities (most recent first):
        run #0: activityrecord{3bc8d7d u0 com.caf.fmradio/.fmradio t52}
    running activities (most recent first):
        run #0: activityrecord{89df584 u0 com.android.launcher3/com.android.searchlauncher.searchlauncher t51}
c:\users\administrator>adb shell pm clear com.caf.fmradio
success
c:\users\administrator>
