I'm using the following code to play mp4 from obb APKexpansion file using APKExpansionSupport lib:

ZipResourceFile expansionFile = null;
AssetFileDescriptor mAFD= null;
try {
    expansionFile = APKExpansionSupport.getAPKExpansionZipFile(this, 1, 0);
    mAFD = expansionFile.getAssetFileDescriptor(strVideoFile);
} catch (IOException e) {
    e.printStackTrace();
} catch (NullPointerException e) {
    e.printStackTrace();
}
    if (expansionFile==null || mAFD == null){
        Toast.makeText(this, "obb is not here or doesn't contain file: "+strVideoFile, Toast.LENGTH_LONG).show();
        return false;
    }
        mMediaPlayer.setDataSource(mAFD.getFileDescriptor(), mAFD.getStartOffset(), mAFD.getLength());

Remember - you have to pack obb zip archive without any compression level. This is very important. It must be a zip archive with no compression (level=0).
However there is a URI mentioned in APKES docs (speaking of VideoView) but I cant get a glue how to get the URI from APKES. Finally I found how to do it here So to use URI you has to extend com.android.vending.expansion.zipfile.APEZProvider like in his example and make changes to Manifest and it should work.
