create a sub directory in asset directory on run time in android

Question

Can anybody tell me how to create a sub folder in asset folder at run time and copy the files from res folder to my assets sub folder?

Answer 1

It is not possible to do this in runtime.

Answer 2

As far as I know this is not possible because of security restrictions. Your asset folder is merged with all your other files into one .apk package. That's your app ready for deployment.

When installing the package the user is asked if he's granting a set of privileges to the app such as accessing private data (text message, contacts) as well as technical stuff like writing on the external storage (SD card).

At this moment you can't modify your asset folder any more because it became a part of the app and application's code and resources may not be change after installation.
