Firstly, you say that your files are in the assets folder, which means that they are bundled with the apk and are read only. Therefore, it is not possible to write data to this part of your app, and hence you cannot update it.

Here’s what I would recommend:

1. Don’t bundle anything with your app. Instead, download the images etc. on the first run of the app, preferably to the external storage if they take up more than a bit of space. Downloading to the internal storage it possible, but most devices have very limited internal storage, and your app is a candidate for immediate uninstall if it hogs this space.
2. Setup a webservice on your server in whatever language you like that can report the latest update date of the files and provide them for download if required.
3. Whenever your app is run, check the last modified date of the downloaded files vs. the last update date provided by your webservice. If the file has been updated since it was downloaded, download it again and overwrite the old one.
