List all files and folders (also Subfolders) in Assets Directory in my App and check if an asset is a file or a folder

Question

I want to check if the asset in Assets directory of my Android App is a File or a Directory.

I have already tried every solution available anywhere on internet including StackOverflow.

Most of the solutions use

File myFile = new File(path);

then check for myFile.isDirectory(); or myFile.isFile();

But it works only if I have my files and directories anywhere else other than under the Assets directory.

Any suggestions will be highly appreciated.

Here is a solution to my problem that I found out working 100% listing all directories and files even sub-directories and files in subdirectories. It also works for multiple levels.

Note: In my case

1. Filenames had a . in them. i.e. .htm .txt etc
2. Directorynames did not have any . in them.

Note: about -- path --

1. to get all files and directories in Assets root folder

   String path = ""; // assets

2. or to get files and directories in a subfolder use its name as path

   String path = "html"; // <<-- assets/html

   listAssetFiles2(path); // <<-- Call function where required
   //function to list files and directories
   public void listAssetFiles2 (String path){
   String [] list;
   
   try {
       list = getAssets().list(path);
       if(list.length > 0){
           for(String file : list){
               System.out.println("File path = "+file);
   
               if(file.indexOf(".") < 0) { // <<-- check if filename has a . then it is a file - hopefully directory names dont have . 
                   System.out.println("This is a folder = "+path+"/"+file);
                   if(path.equals("")) {
                       listAssetFiles2(file); // <<-- To get subdirectory files and directories list and check 
   
                   }else{
                       listAssetFiles2(path+"/"+file); // <<-- For Multiple level subdirectories
                   }
               }else{
                   System.out.println("This is a file = "+path+"/"+file);
               }
           }
   
       }else{
           System.out.println("Failed Path = "+path);
           System.out.println("Check path again.");
       }
   }catch(IOException e){
       e.printStackTrace();
   }
   

   }

Thanks
