It did not occur to me before leaving for China how much of my getting around relies on Google. I am looking for solutions that can be implemented from within China (since I didn't prepare sufficiently in advance).
The two big things are maps, and e-mail. (I've been using Bing as a second-rate substitute for search that is reasonably navigable in English—I had a hard time figuring out the Baidu interface—but I would be interested in other suggestions.)
For maps, I know I could have downloaded an offline map before leaving, so I didn't. I can use OpenStreetMap on my computer, but I'd like something I can use on my Android phone for turn-by-turn navigation. I know I could have downloaded offline maps in advance, but I didn't, so I'm looking for a solution that can be implemented from within China.
For e-mail, … well, I guess mostly I just have to do without, but all flight-related communications from my airline (Delta) go through my GMail address. Is there any way to have access to them so that I don't miss important information? (Probably the answer to this one is just 'no'. I see after posting that this part of the question is a duplicate.)
