编译android sdk 遇到的问题

类似“W/ResourceType( 2888): Unable to get buffer of resource asset file ”这样的错误。是编译sdk的时候设置不正确。
正确的方法是：
在make sdk之前先执行'lunch sdk-eng'或者是：在没有执行过'build/envsetup.sh'的shell终端中直接执行'make PRODUCT-sdk-sdk'

Re: "Using lunch master without the GUI. No such file: sdk-eng." error while building

The command is not "./build/envsetup.sh", it's "source
build/envsetup.sh", abbreviated as ". build/envsetup.sh".

Without that, the Android lunch command doesn't get added to your
shell and you're falling back to some other command installed on your
system that has nothing to do with Android.
