OutOfMemory in MuPdf

Hello, I use the MuPdf library in my project to view documents. The problem is that when you open 3-7 documents in action on 11 inches on the tablet, I get a memory overflow. When you upload a new document, all links to the previous document are destroyed, but the image of the document from memory is not deleted. objects are created in a 10-12 megabyte memory image. on a 7-inch tablet, this problem does not occur.

Perhaps someone ran into this problem?

This issue is resolved by calling recycle()in a bitmap in the relaeseBitmaps()PageView.java method

public void releaseBitmaps() {
        reinit();
        mEntireBm.recycle();
        mPatchBm.recycle();
        mEntireBm = null;
        mPatchBm = null;
    }

Inside mupdf.c find

"/* 128 . . */"

, PageView.java , , .

if (mEntireBm == null || mEntireBm.getWidth() != newSize.x
                              || mEntireBm.getHeight() != newSize.y) {
            mEntireBm = Bitmap.createBitmap(mSize.x, mSize.y, Bitmap.Config.ARGB_8888);
            System.gc();//Added
            Runtime.getRuntime().gc();//Added
        }
