Android: How to find the absolute path of the assets folder?

I need to get the absolute path of the assets folder in my app as I want to serve the files within using a webserver and it needs the absolute path. Is this possible?

I would have thought there might be something like this:

String rootDir = getAssets().getRootDirectory();

but there's not.

Any help appreciated, cheers.

If you have any asset like PDF file stored inside assets folder then get its path using below line:

/assets/file_name.pdf

As mentioned, Android assets cannot be accessed with absolute paths in the device file system. So whenever you have to provide a filesystem path to a method, you're out of luck.

However, in your case there are additional options:

I want to serve the files within using a webserver and it needs the absolute path.

Needing the absolute path is only true if you want to serve the file as a static file with the default mechanism a webserver provides for that. But webservers are much more flexible: you an map any path in an URL to any data source you can access: files, databases, web resources, Android resources, Android assets. How to do that depends on the web server you use.

For example, you can define for youself that any URL starting with https://example.com/assets/ should be mapped to the assets folder of your Android APK. You can then open the asset as an InputStream and serve the content to the webserver's client.

You can always copy files from the assets directory in the APK to a folder on the device, then serve that folder.

Is this possible?

No. There is no "absolute path of the assets folder in [your] app". Assets are stored in the APK file.

In select cases, such as URLs supplied to a WebView, you can use the special file:///android_asset base URL to reference files in your assets.
