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_engineeringwangjIE@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  masterwangjIE@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.shincluding device/generic/mini-emulator-arm64/vendorsetup.shincluding device/generic/mini-emulator-armv7-a-neon/vendorsetup.shincluding device/generic/mini-emulator-x86_64/vendorsetup.shincluding device/generic/mini-emulator-x86/vendorsetup.shincluding device/generic/uml/vendorsetup.shincluding device/Google/muskIE/vendorsetup.shincluding device/Google/taimen/vendorsetup.shincluding device/qcom/common/vendorsetup.shincluding device/qcom/qssi/vendorsetup.shincluding vendor/partner_gms/products/vendorsetup.shincluding vendor/qcom/opensource/core-utils/vendorsetup.shincluding vendor/qcom/proprIEtary/common/vendorsetup.shincluding vendor/qcom/proprIEtary/prebuilt_HY11/vendorsetup.shCreated 9 symlinks out of 9 mapped links..including sdk/bash_completion/adb.bashwangjIE@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$ lunchYou're building on linuxLunch 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-userdeBUGdevice/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 40device/qcom/msm8937_64/msm8937_64.mk:42: warning: "Build with 4.9 kernel"============================================PLATFORM_VERSION_CODEname=RELPLATFORM_VERSION=9TARGET_PRODUCT=msm8937_64... ...HOST_CROSS_2ND_ARCH=x86_64HOST_BUILD_TYPE=releaseBUILD_ID=PKQ1.190601.001OUT_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$ mmRestriction Checker not present, skipPing..device/qcom/msm8937_64/msm8937_64.mk:42: warning: "Build with 4.9 kernel"============================================PLATFORM_VERSION_CODEname=RELPLATFORM_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.typeuserdeBUGC:\Users\administrator>adb rootC:\Users\administrator>adb remountremount succeededC:\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/FM2C:\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.fmradioSuccessC:\Users\administrator>
