Hi,

after the first start of my application the first opened document is rendered correctly. If I open the same document once again, all texts in the document are not rendered. Did I miss something? My setup:

I call Global.Init(this) in my activity, then open a Fragment with PDFLayoutView provided by your test application. In my Fragment I open the file with:
document = new Document();
document.Open(documentPath, "");
pdfView.PDFOpen(document, this);

in onDestroyView() of my Fragment I call:
pdfView.PDFClose();
document.Close();
super.onDestroyView();

and in onDestroy() of my Activity:
Global.RemoveTmp();

It seems second time fonts are not instantiating properly.
Is your pdf file embedding fonts?
Is your pdf file relying on external fonts?

I think the fonts are embedded, At least if I set a PDFFontDelegate on the document it is not being called.

Where are you calling Global..init?
Try not calling the RemoveTmp then let's me know.

I call Global.init in the onCreate Method of my activity.

If I do not call RemoveTmp the document is shown properly.

I could expect that your file isn't containing all the embedded fonts and some resources are taken from the temporary directory.
Cleaning it up such resources, moved in the tmp while Init() is executed, are completely absent after the RemoveTmp.

To double check it: may you forward one of your PDF file?
We will look at it.
