How I can compile android from source by myself?

I was follow step by step, re-follow step by step but allways error for compile full android or u-boot only.

i follow this tutorial http://www.udoo.org/docs-neo/Advanced_Topics/Compile_Android_From_Source.html
Hallo udoo admin, could you test your tutorial?

I attached file.

My System:
Host = Core i7, Windows 7 64bit
Guest = Ubuntu 16.04 64bit, RAM 3GB, CPU Core 2, Swap 2GB, HD 100GB

 

What's your board? Neo or Dual/Quad?

 

Udoo Dual.
Can you give me another tutorial tested budy?

 

Follow this tutorial: http://www.udoo.org/docs/Advanced_Topics/Compile_Android_From_Source.html

 

I've tried to follow the tutorial above, but always just errors like the file log.error I included above.
What else ?

 

Try to install the package liblz4-dev

 

I had also to do this to generate that static library: https://gerrit.omnirom.org/#/c/15028/1/lib/Android.mk

That is: add to extemal/lz4/lib/android.mk this lines:

include $(CLEAR_VARS)
LOCAL_MODULE := liblz4-static
LOCAL_SRC_FILES := $(liblz4_src_files)
LOCAL_MODULE_TAGS := optional
include $(BUILD_STATIC_LIBRARY)

Good luck
