Is there any Android distribution statistic for single countries?
Here you can find statistics of mobile operative systems reach by country, based on the web traffic generated by mobile devices. The web interface gives the possibility to filter the data, choose the country, differentiate by distribution of OS. The data are collected by the domain registry Afilias, which manages domain names like .org, .mobi and .info. Of course the statistics cannot be precise, as they are bounded to accesses on the particular domain names owned by Afilias, but I think they can serve well for an overview.
