如何使用纬度和经度获取地址信息？

Question

I made this tutorial for get user's address and location but I got error when I changed AVD's location. When I didn't call getCityName function at getLastLocation function, I can get user's location but when I call it, it gave that error. How can I solve it?

it was give an error which was :

Edit: I tried real device, location services working well I can get city name, street name etc. But in simulator it was give error again. I tried to change AVD's location after that it was going to crash. I believe solution is simple but I don't know how can I search this situation.

Try run the operation in a new Thread, and then if I need to update some UI view I'll do it on runOnUiThread.
