Does Android apk require pre-decompression

Today, when visiting the forum, I found a friend asked the question.
The main purpose is to achieve the first time the player enters the game, or a new version installed, the APK decompression, write to the SD card.
This way, the game will no longer read resources from the APK during the run. To improve efficiency.
I also see this in the code of "Don Gate World".
And I have other friends, I did not deal with this matter, efficiency is not too much impact.

This brings me back to this tangled emperor again.

After the discussion in the forum to decide, or to see the project, if there is demand, add, if not the problem. Even if it is.
