I recently read a fact about glycosides:

Strong reagents like $\ce{C6H5NHNH2}$ or $\ce{NH2OH}$ are required to decompose it and acidic hydrolysis fails to do so.

Why is it so? What makes it different from other hemiacetals which can be decomposed by both acidic and alkaline hydrolysis?

This information is wrong. Glycosides do undergo acidic hydrolysis. The accepted mechanism of this hydrolysis is as follows1:
