Treating A20 boards like outdated piece of HW by vendors makes building Android
for Cubietruck not trivial task. Finding documentation, mailing list or blog
post that clearly describe steps is almost impossible. Most of links to SDK are
broken and instructions outdated. Because of that I decided to leave couple
notes for me and all of you lost in this madness.
Hopefully below steps can build foundation for future development and
improvements.
Get the code
It took me couple of googling hours to realize that key was to carefully search
cubietech sever.
Edit 19.06.2023: There is no possibility to download this repo nowadays.
Based on other
instruction
that I hit previously (but download link was broken) I run build process:

After some digging I managed to narrow down issue to piece of smart code, that
injected version string through define, which generated above mess. Without
thinking much about fix I just changed incorrectly generated define to driver
version string. This string will be presented in UMP modinfo. Patch which fix
above looks like that:

Android
I assume you directory layout looks like this:
1

3

.
├── a20-android4.2_android
└── lichee
|
Go to Android directory and source environment setup script. Android do not like
shells other then bash, so change you shell if you using something different:
1

|
cd a20-android4.2_android
bash
source build/envsetup.sh

You will get menu which will look like this:

Then update and install required Java SDK.

You also may need to update alternatives if Java SE 1.6 was installed
previously:

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip xsltproc

Summary
As you can see Android boots to initial screen and it looks like we have working
prcedure for building Cubietech Android SDK. This gives good ground for future
experimentation.
Hopefully above instructions works for you and will not outdate soon. If you
found any problems/errors please let me know in comment. I you think content can
be useful to others please share.
Thanks for reading.
