经过从下载到编译的二十多个小时…终于成功的img编译出来了。先写一下遇到的两个坑，有空再写一下过程。

环境

Ubuntu 16.04JDK1.6Android_4.4.2

坑一

/content/common/android/hash_set.cc 报错，错误信息大概是这样的(来自百度)：

In file included from externalromium_org/content/common/android/hash_set.cc:5:0:out/target/PRoduct/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:10:26: error: extra tokens at end of #ifndef directive [-Werror]out/target/product/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:11:26: error: missing whitespace after the macro name [-Werror]out/target/product/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:24:20: error: expected initializer before '<' tokenout/target/product/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:26:17: error: expected initializer before '<' tokenout/target/product/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:29:22: error: expected '{' before '<' tokenout/target/product/xxx/obj/GYPd_intermediates/content/jni/HashSet_jni.h:29:22: error: expected unqualified-id before '<' tokenexternalromium_org/content/common/android/hash_set.cc:30:1: error: expected '}' at end of inputcc1plus: all warnings being treated as errorsmake: *** [out/target/product/xxx/obj/STATIC_LIBRARIES/content_content_common_gyp_intermediates/content/common/android/hash_set.o] 错误 1

原因是javap的版本，Android4.4.2需要用JDK1.6编译，除了要设置java、javac的版本之外还要设置javap的版本，方可解决这个错误。

sudo update-alternatives --install /usr/bin/javap javap /home/jdk1.6.0_45/bin/javap 300sudo update-alternatives --config javap

修改版本之后最好重新运行一下source build/envsetup.sh和lunch

坑二

Checking API: checkapi-last 报错，错误信息大概是这样的(来自百度)：

不要问我为什么错误信息都是来自百度..反正就是一大堆的api/19.txt:*****： error *： Removed xxxxxxxxxxxxxx。原因未知，解决方法如下： 1. 先运行

make update-api搜索文件current.txt(不要问我为什么要用搜索，因为我没记住路径)，打开那个创建/修改时间离现在最近的文件，全选 - 复制。打开prebuilts/sdk/api/19.txt(你的Android系统版本号)，全选 - 粘贴。make,成功(不用clean，可以继续编译…到这里已经离成功很近了)。若还报错，请检查的java、javac、javadoc、javap版本。
