Error in AreaBreak method in iText7 Android-Java

Question

I am outputting Pdf document with iText7 library in my android application. When I press the button once, I get pdf output (for example: namelastname.pdf), when I click it for the second time, pdf is created again and its name is (namelastname(1).pdf), but at that moment my application crashes and when I look at the file directory, I see that it has 0 bytes in size. My error is: com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy object to current pdf document.

E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.gokhankopuz.kopuzfilo, PID: 13704
com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy object to current pdf document.
