android get list of files from package

Issue

How can I get all list of .json config files, which are located NOT on SD card, but in my package? Bellow on the image showed the files in the folder which I want to access. The idea is the following: when application starts I want to get list of config files, the path to them and display that to testers to choose to what server connect to. How can I do that? I was looking for PackageManager and AssetManager, but resultless.

When I put folder configs to folder assets, this code game me a list of available configs, but how can I get full path to them to read them?

AssetManager am = getAssets();
String s = getPackageName();
Resources tmp = pm.getResourcesForApplication(s);
String [] arr = am.list("configs2");

Solution

I finally solved my problem. This is the structure of my project:

1. To get list of files from application package, you need to put all your files you want to get into assets folder. Here is the code:

   private ArrayList getPackageConfigList() { AssetManager am = getAssets(); String [] arr = null; try { arr = am.list(folder); } catch(IOException e) {e.printStackTrace();}

               ArrayList<String> flist = new ArrayList<String>();
   
               for (int i=0; i<arr.length; i++)
               {
                   flist.add(PKG + arr[i]);
                   Log.d(tag, PKG+ arr[i]);
               }
   
               return flist;
           }
   

   2. To read concrete file from package:

   private String loadConfigFromPackage(String fileName) { AssetManager am = getAssets(); InputStream in = null; String result = null;

   try
   {
       //open file, read to buffer, convert to string
       in = am.open(folder + "/" + fileName);
       int size = in.available();
       byte[] buffer = new byte[size];
       in.read(buffer);
       in.close();
       result = new String(buffer);
   }
   catch(IOException e)
   {
       e.printStackTrace();
   }
   finally
   {
       try
       {
           in.close();
       }
       catch(Exception ex){}
   }
   return result;
   

   }
