How to speed up the launch of an android application?

Question

Android

There is such a problem: after installing the apk application on the phone, the first launch of the application lasts from 5 to 15 seconds. Subsequent launches are fast, without problems.
With what it can be connected? Can you give any advice on speeding up the first launch or optimizing the application as a whole?

Answer 1

without seeing the application it is difficult to say something about
the application who wrote it, you? if not, then it is likely that the application caches / loads / grinds its information into a faster form.
