Remove the option menu in top on touch the screen

This is my app screenshot, i hidden the other options in menu. only displaying the option to change the file scrolling.
Even i changed default view in Global.java class but not applying it. You can identify in the screen shot, Vertical scrolling.

It seems you wasn't confirming the image upload or the file was really big.
May you retry?

If your preference is “continuous horizontal scrolling”: it’s implemented in the old PDFView class and not yet moved to the new PDFLayout.
The reason that mode is not yet moved is due to some priorities and few requests from customers.
The feature is already in roadmap and will be distributed later in the mid of October.

For setting def_view, make sure that you are changing the value in Global.default_config method, or it will be overriden.
Generally:
Make sure that you are setting it before opening the pdf, or that you are using PDFLayoutView.PDFSetView.

As it's called in PDFLayoutView.PDFOpen:
You can also use RadaeePDFManager.setReaderViewMode (needs to be called before show/open methods)

Now i'm able to change the default view. But how to remove top menu bar which is appearing on touch on screen.?

I didn't understand below line
It seems you wasn't confirming the image upload or the file was really big.

You need to change PDFViewController.OnBlankTapped, something like:

case BAR_NONE:
//m_bar_cmd.BarShow();
m_bar_status = BAR_NONE;

If you need to hide it in all cases, then you need to handle all cases of m_bar_cmd.BarShow();
