ANDROID_BUILD_TOP not set

[tianyishan]

I ran into this error while building the example code. I tried to export ANDROID_BUILD_TOP in my bash profile. Didn't work. I also browsed the previous questions. Didn't really help. I have sdk and ndk installed. So now I am really confused. Please help. Thank you.

If I recall correctly, you probably need to set ANDROID_NDK_HOME, or put ndk-build in your path so it can be discovered by the Makefile.
