For Android smartphones, is it possible to set the loudness in decibel for the headphone jack or internal speaker instead of using the percentage Loudness?
I want to produce a sound which loudness is the exact same across all smartphones.

No. Differing sensitivities of headphones would make this impossible, even if you could standardise the voltage at the headphone jack.
