• I should put my folder in res or asset which one is better?
• Can I path folder by string path (I've tried it but didn't work for me)

Answer 1

Better and most suitable way is to put your asset in res folder. After that you can assess them like this.

 Drawable image = getResources().getDrawable(R.drawable.your_file_name_goes_here);
