How to acces file outside of .apk

Hello~~~

(I hope you will undrstand for my bad English)

I develop a game based on Android platform.

This app contain many resource files and when I package the app, it seems that all resources packaing into the apk file.

But I have the problem when I access (exactly calling function - file::open), it takes too much time.

I could get this result after profiling my app.

And I had some test for loading speed.

In first case, I was packaging with dummy files which is not using. Thease files were not accessed. (not trying to open)

But strangely, It takes more times. So I guess If I try to acces the file, the apk file would be unpackaged.

I hope that there is any solution to improve loading speed. But unfortunately If there is no solution for it, I want to ask how to I avoid packaging my resources

outside of apk and how to I access thease file.

It's really very important issues T,,T)...

Please any body give me a solutioin.

Thank you.
