Itext7 Stopped at PdfWriter with FileNotFoundException Error - android-studio

Question

I tried to make PDF file with Itext 7.2.2 and it just stop working at PdfWriter (im using Log to find where it stop) but the application doesnt crash. Here is my part of the code:
public void createPDF(ArrayList<ModelAttendance> arrayListAttendances, Integer attendeeCount){
try{
Log.i(TAG, "Create PDF with " +attendeeCount +" Attendee");
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Kegiatan/" + eventNama + ".pdf";
File file = new File(path);
file.mkdirs();
PdfWriter writer = new PdfWriter(file);
PdfDocument pdfDoc = new PdfDocument(writer);
Document document = new Document(pdfDoc, new PageSize(612, 936).rotate());
document.setMargins(0,0,0,0);
...
}
}
This the error:

Answer 1

I change my code from:
File file = new File(path);
file.mkdirs();
To:
File root = new File(path);
if (!root.exists()){
root.mkdirs();
}
File file = new File(path + eventNama + ".pdf");
if(root.exists()){
file.delete();
}
file.createNewFile();
FileOutputStream outputStream = new FileOutputStream(file);
