Answer 1

I've seen several questions on the same issue but it seems like none of them got a good and deterministic solution. The most common suggestion is to make sure you have the correct permission (which I see you do in your question) and there are some that say that this only works on 2G and not 3G.

Take a look at the following similar questions. It might point you in some new directions:

getNeighboringCellInfo() returning null list

Null Issue with NeighboringCellInfo, CID and LAC

Get neighboring cell in Android returns null

Answer 2

getNeighboringCellInfo() is deprecated in android . You should use getAllCellInfo() and save output of that in a List and using a loop on each element of List decide which is neighbor using element.isRegistered() . NeighboringCells have isRegistered() == false .
