Add /tools to your path or instead of jobb use path/to/sdk/tools/jobb.bat

which type of files are put in these obb files

Big ones. Like drawables, sounds etc. Then, for example, you can use this code to put drawable file into ImageView:

imageView.setImageBitmap(
    BitmapFactory.decodeFile(
        sm.getMountedObbPath("/path/to/obb/file") + 
        "path/to/file/in/obb.png")

or, play sound:

mp.setDataSource(AcItem.this, 
    Uri.fromFile(new File(
        sm.getMountedObbPath("/path/to/obb/file") + 
        "path/to/file/in/obb.png"));
mp.prepare();
mp.start();

As I promised, GitHub link to my obb manager class: https://github.com/uncleLem/AndroidUtils/blob/master/src/io/github/unclelem/androidutils/utils/ObbExpansionsManager.java I hope it would help.
