            try {
                files = assetManager.list("");
            } catch (IOException e1) {
                e1.printStackTrace();
            }
            for (int i = 0; i < files.length; i++) {
                File file = new File(files[i]);
                try {
                    Scanner scanner = new Scanner(file);
                    while (scanner.hasNextLine()) {
                        Log.e(" ", " " + scanner.next());
                    }
                    scanner.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }

You cannot use the File class for a 'file' in assets folder. This is because File can only handle real files on the file system. Instead your only option is to call assets manager to open an inputstream fot the assets file and read from that stream. Examples have been posted many times on this forum.

The AssetManager.list gives a path that is relative within the assets. If you need to open a file, you need to provide an absolute path of the file. For assets files, you can use the AssetManager.open method.
