编译android sdk问题汇总：

官方的文档和问题：

src/sdk/docs/howto_build_SDK

$ . build/envsetup.sh

$ lunch sdk-eng

$ make sdk

Package SDK: out/host/darwin-x86/sdk/android-sdk_eng._mac-x86.zip

make window sdk 需要mingw的支持

$ make win_sdk

实际工作的步骤

1. 修改 ”\4030\external\libvpx\vpx_config.h” 如下

//#define CONFIG_ARM_ASM_DETOK 1

2. $ source build/envsetup.sh

lunch 1 ; make

3. $ lunch sdk-eng

4. $ make sdk

在 out/host/linux-x86/sdk/android-sdk_eng.xxxx_linux-x86.zip 下

注意： android-sdk_eng.xxxx_linux-x86.zip 並不包含 emulator,

你必須手动將out/host/linux-x86/bin/emulator 复制到 android-sdk_eng.xxxx_linux-x86.zip/android-sdk_eng.xxxx_linux-x86/tools/ 下

问题汇总，qcom的BSP也有许多问题。在android 标准的sdk上修改了许多。有些在原先在android标准的版本上没有的：经历了几个版本，问题先后记录如下：

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
ERROR 1：
error: undefined reference to 'vp8_decode_mb_tokens_v6'
make sdk error:
target SharedLib: libstagefright (out/target/product/generic/obj/SHARED_LIBRARIES/libstagefright_intermediates/LINKED/libstagefright.so)
prebuilt/linux-x86/toolchain/arm-linux-androideabi-4.4.x/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld: out/target/product/generic/obj/STATIC_LIBRARIES/libvpx_intermediates/libvpx.a(detokenize.o): in function vp8_decode_mb_tokens:external/libvpx/vp8/decoder/detokenize.c:223: error: undefined reference to 'vp8_decode_mb_tokens_v6'
collect2: ld returned 1 exit status
make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libstagefright_intermediates/LINKED/libstagefright.so] 错误 1

修改方法：
1. 修改 ”\4030\external\libvpx\vpx_config.h” 如下

//#define CONFIG_ARM_ASM_DETOK 1 这句话是针对armv6的。sdk的模拟器是armv5，所以不需要

ERROR2：

解决办法：

这里的framework目录指的是：~/Android_Src/out/host/linux-x86/framework 这个目录，

是sdk/build/tools.atree这个文件有bug，上面那几个文件的路径写的不对，其实在

Src/out/host/linux-x86/framework 目录下是有这几个文件的，

$cp ~/Android_Src/prebuilt/common/pc-bios ~/Android_Src/usr/share

$ cd ~/Android_Src/out/host/linux-x86/framework

$cp ddmlib.jar ddmlib-test.jar
