[Android] I always want to open the first page when I open a pdf file from a reader

Hello 오승훈오,

Sorry for the delay in response to your query and apologize for the inconvenience caused. As per the description above, you want to open the first page of a PDF file always in Adobe Reader, Is that correct?

Please refer to the following KB link Acrobat Reader Help for Android: Opening PDFs Link: https://www.adobe.com/devnet-docs/rm/android/acrobatandroid_en/open.html

You can also set the first page from File > Properties > Initial View (tab) > Layout and Magnification > Open to page.

Hope this helps, and keep us posted with the results.

Regards,

Anand Sri.
