I've bought the license to use Radaee in Android app.
I need to setup the pdf using a ViewPager, I found the example in RDPDFReader..
But the PDFViewPager throws an out of memory exception after some pages.

I was looking into PDFViewPager implementation and I found an array with the pages, and it's never released by GC.
maybe this is the problem.. I really don't know how can i solve this. I need to implement my own viewpager with my own adapter?

hi, u maybe using old version.
plz check codes for PDFViewPager class, there are implment codes for PagerAdapter:
    private class PDFPageAdapter extends PagerAdapter
    {
        private Document m_doc;
        public PDFPageAdapter(Context ctx, Document doc)
        {
            m_thread = new VThread(m_hand_ui);
            m_thread.start();
            m_thread_cache = new VThread(m_hand_ui);
            m_thread_cache.start();
            int cnt = doc.GetPageCount();
            m_pages = new PDFPageView[cnt];
            m_doc = doc;
            int cur;
            for(cur = 0; cur < cnt; cur++)
            {
                m_pages[cur] = new PDFPageView(ctx);
                //m_pages[cur].vOpen(m_thread, m_thread_cache, doc, cur, m_fit_type);
            }
        }
        @Override
        public java.lang.Object instantiateItem(android.view.ViewGroup container, int position)
        {
            if(!m_pages[position].vIsOpened())//lazy loading.
                m_pages[position].vOpen(m_thread, m_thread_cache, m_doc, position, m_fit_type);
            container.addView(m_pages[position]);
            return m_pages[position];
        }
        @Override
        public int getCount()
        {
            return m_pages.length;
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object)
        {
            m_pages[position].vFreeCache();
            container.removeView(m_pages[position]);
        }
        @Override
        public boolean isViewFromObject(View view, Object o)
        {
            return view == o;
        }
        @Override
        public CharSequence getPageTitle(int position)
        {
            return "Page:" + position;
        }
    }
callback method destroyItem shall free memories.
