Could I apply for a visa for the People's Republic of China in Indonesia, if I dont have Indonesian nationality and have my permanent residence in Germany (my nationality is Polish)?

I will travel to Indonesia at 30.12. 2009 and from there, at 19.04.2010 directly next to China (jump on over Malaysia). Ill arrive Shanghai on 24th April.I would prefer to apply for a visa already in Germany before leaving for Indonesia, but that doesnt work, because the visa is valid for only 3 months after the issue.
