But in some PDF annoation added but in some PDF no added.
But some time annotation added in that file.
I can't under stand for real issue
reply here,it's urgent call.

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);
m_rPDF.m_view.vRender(vpage);
float[] rect = { 200, 200, (200 + bitmap.getWidth()),
(200 + bitmap.getHeight()) };
boolean b = pa.AddAnnotBitmap(bitmap, true, rect);
int count = pa.GetAnnotCount();
Log.e("TAG", b+ " annoation Annot count" + count);
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);
int dib = Global.dibGet(0, (int) m_doc.GetPageWidth(c_page),
(int) m_doc.GetPageHeight(c_page));
pa.RenderPrePare(dib);
pa.RenderToBmp(bitmap, mat);
m_rPDF.m_view.vRender(vpage);

1. Global.tmp_path + "/temp.dat" only can be used in 1 document object, the second document shall failed.
2. to be sure Constant.currentpage has exist in all PDF file.
3. to be sure (200, 200, 200 + bmp.width, 200 + bmp.height) are all at page area.
codes like:
m_doc.Open(...);
m_doc.SetCache(Global.tmp_path + "/temp.dat");
Page page = m_doc.GetPage(pageno);
page.ObjsStart();
page.AddAnnotBitmap(bmp);
Bitmap bmp_render = Bitmap.Create(...RGBA32);
bmp_rendr.erase(back_color);
page.RenerToBmp(bmp_render);
page.Close();
bmp_rendr.recycle();
m_doc.Close();
