Looking at Wikipedia entries, Google’s ID by appearance seems good (but might also be a Painted Stork). However, Yellow-Billed Storks are African, and Milky Storks South-East Asia, so given the OPs location, the latter seems more likely.
I find the Cornell Lab’s Merlin Photo ID very good, but it would be too much time & effort to download the SE Asia pack for one photo :)
