to be sure you freed all Bitmap data using Bitmap.recycle(), which Bitmap allocated by yourself.
and invoke PDFView.vClose() to free PDFView or PDFThumbView.
PDFView may takes 12M memory to allocate Bitmap, when zooming.

I am closing all open things as below.

Code:

if (m_thumb != null) {
				m_thumb.thumbClose();
				m_thumb = null;
			}
			if (m_reader != null)
				m_reader.PDFClose();
			if (m_doc != null)
				m_doc.Close();
			if (mContentView != null)
				mContentView.removeAllViews();

But i don't have an Bitmap related variable.But still it gives me blank screen.When i zoom out again it show me the pdf.This happens after when i try to zoom several pdfs.
