How can I access files in res/raw folder or any other location in android?

Question

I posted a day ago similar question, but I simplified my problem here so hoping to get resolved. I think I know when reading a file with 'filename.ext', I use

InputStream inputStream = getResources().openRawResource(R.raw.filename);

But how I can access multiple files? I need a function looks like

InputStream inputStream[] = getResources().openRawResource(R.raw.*.*);

Thanks!

If you place your files in assets/ instead of res/raw/, then something like this might work for you:

    AssetManager am = getAssets();
    String assetFileNames[] = am.list("");
    InputStream inputStream;
    for(String assetFileName : assetFileNames) {
        inputStream = am.open(assetFileName);
        // Replace with whatever you want to do with the file here
        processAssetFile(inputStream);
        inputStream.close();
    }

Note that several of the methods above throw java.io.IOException, which you'd have to handle in your own implementation.
