Depends on the context. आदमी is a lot like the English word 'man' in that it is sometimes used to mean 'human' or 'person' but is still an explicitly gendered word.

Eg: 'कुत्ता आदमी का सबसे अच्छा दोस्त है'- Dog is man's best friend. Here, you are making a generalised sentence where आदमी does mean human.

'आम आदमी'- Common man. Usually includes women but you can also have sentences like भारत की आम औरत आम आदमी से कम कमाती है (The common woman of India earns less than the common man).

It may also introduce some ambiguity. 'कल हमारे सारे आदमी हड़ताल पर होंगे' - 'Tomorrow, all our men (may mean 'workers' here in this context) will be on strike'. Will the female employees also be on strike or will they be working as usual?

In general, if you are comfortable using the word 'man' in an English sentence, you can probably translate it to आदमी.
