How to avoid OutOfMemoryError

Hello,

I am developing an android app which uses the pdf sdk (latest version) in a viewpager. Before I open the document, I called vClose() to avoid memory leaks (I got an OutOfMemoryError without that).

But now, I sometimes got another error which seems to be deeper in the library:

09-16 10:36:53.593 17291-17291/de.***.meinort W/Adreno-GSL﹕ <sharedmem_gpumem_alloc_id:1489>: sharedmem_gpumem_alloc: mmap failed errno 12 Out of memory

How can I avoid this crash?

Thanks for your help!

what mean of:
m_pdv = new PDFCustomView(getContext());
m_pdv.vClose();
???

as i tink, it should be:
if( m_pdv != null ) m_pdv.vClose();
m_pdv = new PDFCustomView(getContext());

Thanks for your help! I've tried this but it did not solve my problem. I still get the same error:

// Edit:
PS: Now, the OOM occurs when I try to resize the view with m_pdv.vResize(getWidth(), getHeight());

How to solve this issue?

are width and height of view are very large?

or any large bitmaps out of PDFView?
using Bitmap.recycle() to free memory, if you has many Bitmap objects or a large Bitmap object allocated.
