下載源碼遇到的問題一：

這個error信息忘了詳細記錄了，就是某個./repo/projects/.............下面報錯了，把報錯的文件夾刪掉，repo sync

error:

………………………………………………………………………...

Traceback (most recent call last):

File "/Volumes/aosp/android-6.0.1/.repo/repo/main.py", line 531, in

_Main(sys.argv[1:])

…………………………….

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd4 in position 578: ordinal not in range(128)

解決辦法：根據error的提示，刪除./repo/projects/...相應下的git就行了，然后再repo sync

編譯源碼遇到的問題二：

build/core/combo/mac_version.mk:39: * Can not find SDK 10.12 at /Developer/SDKs/MacOSX10.6.sdk

build/core/combo/mac_version.mk:40: *****************************************************

build/core/combo/mac_version.mk:41: *** Stop.. Stop.

配置mac_sdk_versions_supported里添加10.12

編譯源碼遇到的問題三：

system/core/libcutils/threads.c:38:10: error: 'syscall' is deprecated: first deprecated in OS X 10.12 - syscall(2) is unsupported; please switch to a supported interface. For SYS_kdebug_trace use kdebug_signpost(). [-Werror,-Wdeprecated-declarations]

return syscall(SYS_thread_selfid);

^

host C: libcutils <= system/core/libcutils/iosched_policy.c

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/unistd.h:733:6: note: 'syscall' has been explicitly marked deprecated here

int syscall(int, ...);

MacOSX-SDKs下載地址：https://github.com/phracker/MacOSX-SDKs

刪除10.12，下載MacOSX10.11.sdk，解壓拷貝到/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

然后確保AOSP源碼下build/core/combo/mac_version.mk文件中

mac_sdk_versions_supported := 10.9 10.10 10.11

后面不要寫10.12。

編譯源碼遇到的問題四：

找不到com.sun.javadoc.ClassDoc
