解決辦法：
步驟1：找到下載源碼里的art/build/Android.common_build.mk
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),false) （修改處：將true改為false）ture--->false
# By default, host builds use clang for better warnings.
ART_HOST_CLANG := ture
endif
步驟2：直接輸入命令：ln -sf /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld

******************************
You have tried to change the API from what has been previously approved.
To make these errors go away, you have two choices:
1) You can add "@hide" javadoc comments to the methods, etc. listed in the
errors above.
2) You can update current.txt by executing the following command:
make update-api
To submit the revised current.txt to the main Android repository,
you will need approval.
******************************
解決辦法：
2.1 錯誤分析：錯誤信息表明是由于API錯誤導致，進一步研究發現：谷歌對于所有的類和API，分為開方和非開放兩種，而開放的類和API，可以通過“Javadoc標簽”與源碼同步生成“程序的開發文檔”；當我們修改或者添加一個新的API時，我們有兩種方案可以避免出現上述錯誤，其一是將該接口加上 非公開的標簽：/**{@hide}*/；再者可以在修改后執行：make update-api(公開)，將修改內容與API的doc文件更新到一致。
2.2 解決辦法：
步驟1：執行： make update -api ;
步驟2：修改后相應API文件后，在base庫下面會產生“.current.txt”文件的差異，提交時將該差異一并提交審核即可。
