We can't send complete project.
We are using below code for graphic annotation:

public void graphicannotation(Bitmap bitmap)
{
m_doc.SetCache(Global.tmp_path + "/temp.dat");
int c_page = Constant.currentpage;
pa = m_doc.GetPage(c_page);
pa.ObjsStart();
PDFVPage vpage = m_rPDF.m_view.vGetPage(c_page);
float[] rect = { 200, 200, (200 + bitmap.getWidth()),
(200 + bitmap.getHeight()) };
pa.AddAnnotBitmap(bitmap, true, rect);
float m_ratio = ((float) m_doc.GetPageHeight(c_page))
/ ((float) m_doc.GetPageWidth(c_page));
Matrix mat = new Matrix(m_ratio, -m_ratio, 0,
m_doc.GetPageHeight(c_page) * m_ratio);

pa.RenderToBmp(bitmap, mat);
m_rPDF.m_view.vRenderSync(vpage);
pa.Close();
mat.Destroy();
bitmap.recycle();
}


To save pdf:

m_rPDF.PDFEndAnnot();
savedailog(); (here it updates file name)
boolean a = m_rPDF.PDFSave();

onResume() we are not using any object or method of this library.

Can you suggest anything form this?

this line has problem:
m_doc.SetCache(Global.tmp_path + "/temp.dat");
it invoked every time when function "graphicannotation" call.
to be sure: only once of m_doc.SetCache method invoked.

It added by mistake. We are not using it every time. Invoking only once after m_doc.Open().

the simplest debug is:
set debug point in Document.SetCache();
and check it invoked times.

Yes, we have checked that. It invoked only once.
