Thank you @Michel Morais and @Joshua Zhu,  your link is what i need, but i cant compile the first repo. The second link is very useful because its belong to Google. Thank you!

Author of the first repo here. It was quite a surprise to see my study repo listed here.

Anyway, to build it, all you need is gradle. The wrapper will fetch the experimental plugin.

OTOH, I would actually recommend using NanoVG. In fact, I have another repo that uses it, but might be a little overwhelming for what's supposed to be a simple example: https://github.com/TheFakeMontyOnTheRun/dungeons-of-noudar

Feel free to contact me if you need further help.
