Note that it is not related to Basic4android. You will get the same results with Java.
It is hard to answer this question. The answer depends on the specific device you are using.

Ainol tablets is made in China. And I think it is more easy to access to Chinese software.
Only problem is that hope you can read Chinese. And you can also use Google to translate for you.
Hope I can help you.
