Android系統源碼下載與編譯、刷機--Nexus6實測

在設備驅動頁中找到相應的驅動程序sh腳本，並下載
Nexus對應驅動頁：https://developers.google.com/android/nexus/drivers

將這三個壓縮包下載後，解壓縮得到三個sh文件。
將這三個sh文件copy到Android編譯目錄下。

執行這3個sh文件，會下載相關驅動文件到 vendor 目錄

./extract-broadcom-shamu.sh
./extract-moto-shamu.sh
./extract-qcom-shamu.sh

過程中會讓我們看一些聲明信息，看完後輸入I ACCEPT即可：

編譯Android系統

(1).環境初始化

source build/envsetup.sh

執行完後，會將一些文件include進來：

panghu@panghu:~/Android$ source ./build/envsetup.sh 
including device/asus/deb/vendorsetup.sh
including device/asus/flo/vendorsetup.sh
including device/asus/fugu/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-mips/vendorsetup.sh
including device/generic/mini-emulator-x86_64/vendorsetup.sh
including device/generic/mini-emulator-x86/vendorsetup.sh
including device/htc/flounder/vendorsetup.sh
including device/huawei/angler/vendorsetup.sh
including device/lge/bullhead/vendorsetup.sh
including device/lge/hammerhead/vendorsetup.sh
including device/moto/shamu/vendorsetup.sh
including sdk/bash_completion/adb.bash

(2)lunch選擇要build的類型

lunch

執行該命令後，會列出當前可供選擇的build type，對應選擇自己需要的即可

panghu@panghu:~/Android$ lunch

You're building on Linux

Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_arm64-eng
     3. aosp_mips-eng
     4. aosp_mips64-eng
     5. aosp_x86-eng
     6. aosp_x86_64-eng
     7. aosp_deb-userdebug
     8. aosp_flo-userdebug
     9. full_fugu-userdebug
     10. aosp_fugu-userdebug
     11. mini_emulator_arm64-userdebug
     12. m_e_arm-userdebug
     13. mini_emulator_mips-userdebug
     14. mini_emulator_x86_64-userdebug
     15. mini_emulator_x86-userdebug
     16. aosp_flounder-userdebug
     17. aosp_angler-userdebug
     18. aosp_bullhead-userdebug
     19. aosp_hammerhead-userdebug
     20. aosp_hammerhead_fp-userdebug
     21. aosp_shamu-userdebug

Which would you like? [aosp_arm-eng] 21          

機型對照表

(3)開始編譯

make -j8

等待編譯結束………灰常灰常漫長.機器比較好的大概1-2小時，機器不好的，那個酸爽…..!!!!!

編譯結束後提示如下即可：
####make completed successfully ####

刷機

Nexus6關機狀態下,長按音量下+電源,進入recovery模式

然後在源碼根目錄下(Android根目錄下)執行下面命令:

fastboot -w flashall

如果這時候提示：< waiting for device > 的話，證明你的虛擬機VirtualBox沒有識別到你的手機，可以在VirtualBox上菜單中 “設備” -> “分配USB設備” -> 選中你的手機對應的設備名就可以了。

panghu@panghu:~/Android$ fastboot -w flashall
< waiting for device >

結語

OK，到此為止，Android系統下載，編譯，刷機都結束了，大家可以開始自己的Android系統定制之旅了。(PS:原生的弄完後，建議可以去試試弄CM的系統，CM做了一些優化，感覺比較不錯！)
