入职小白随笔之高通项目编译流程
声明:本文来自我的导师wangjie.
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>
