List of files in assets folder and its subfolders

private boolean listAssetFiles(String path) {    String [] list;    try {        list = getAssets().list(path);        if (list.length > 0) {            // This is a folder            for (String file : list) {                if (!listAssetFiles(path + "/" + file))                    return false;                else {                    // This is a file                    // TODO: add file name to an array list                }            }        }     } catch (IOException e) {        return false;    }    return true; } 

Call the listAssetFiles with the root folder name of your asset folder.

    listAssetFiles("root_folder_name_in_assets");

If the root folder is the asset folder then call it with

    listAssetFiles("");    

try this it will work in your case

f = getAssets().list("");for(String f1 : f){    Log.v("names",f1);}

The above snippet will show the contents of the asset root.

For example... if below is the asset structure..

assets |__Dir1 |__Dir2 |__File1

Snippet's output will be ....Dir1 Dir2 File1

If you need the contents of the Directory Dir1

Pass the name of Directory in the list function.

  f = getAssets().list("Dir1");

Hope This Help:

following code will copy all the folder and it's content and content of sub folder to sdcard location:

 private void getAssetAppFolder(String dir) throws Exception{    {        File f = new File(sdcardLocation + "/" + dir);        if (!f.exists() || !f.isDirectory())            f.mkdirs();    }     AssetManager am=getAssets();     String [] aplist=am.list(dir);     for(String strf:aplist){        try{             InputStream is=am.open(dir+"/"+strf);             copyToDisk(dir,strf,is);         }catch(Exception ex){            getAssetAppFolder(dir+"/"+strf);         }     } } public void copyToDisk(String dir,String name,InputStream is) throws IOException{     int size;        byte[] buffer = new byte[2048];        FileOutputStream fout = new FileOutputStream(sdcardLocation +"/"+dir+"/" +name);        BufferedOutputStream bufferOut = new BufferedOutputStream(fout, buffer.length);        while ((size = is.read(buffer, 0, buffer.length)) != -1) {            bufferOut.write(buffer, 0, size);        }        bufferOut.flush();        bufferOut.close();        is.close();        fout.close(); }
