Question

Is there any way to access a file into assets folder by name with regular expression?

Only selected one file but obvious the suffix into the name

Something like:

    aFD =SessionManager.getAppContext().getAssets().openFd("box*.png");

The case:

      /assets/box_1223.png

Answer 1

You should get all files from assets folder

AssetManager amgr = getAssets();
    String[] list = amgr.list("./");
    for(String s : list){
        Log.d("File:", s);
        //check if filename is what you need
        if (s.contains(what you need OR regex pattern)){
            //do staff
        }
    }

You can view all files and take only what you need, by using REGEX or contains()
