I build a new class and make it extends BasePostprocessor, I do nothing in it. But when it ran, the sample throw the above exception; I just use imagepipeline to download the image, don't use the simpledraweeview.

com.facebook.imagepipeline.request.ImageRequestBuilder requestBuilder = com.facebook.imagepipeline.request.ImageRequestBuilder
                .newBuilderWithSource(uri);

        if (imageRequest.getTargetWidth() > 0 && imageRequest.getTargetHeight() > 0) {
            requestBuilder.setResizeOptions(new com.facebook.imagepipeline.common.ResizeOptions(imageRequest
                    .getTargetWidth(), imageRequest.getTargetHeight()));
        }

        requestBuilder.setAutoRotateEnabled(true);
        requestBuilder.setPostprocessor(new FPostProcessor(getImageConfig()));


public class FPostProcessor extends BasePostprocessor{

    private FImageConfig mImageConfig;

    public FPostProcessor(FImageConfig imageConfig){
        mImageConfig = imageConfig;
    }
    /*
    @Override
    public CloseableReference<Bitmap> process(Bitmap sourceBitmap, PlatformBitmapFactory bitmapFactory) {
        return super.process(sourceBitmap, bitmapFactory);
    }*/
    }

I suppose you're not handling the lifecycle of the underlying bitmap correctly. You have to keep the CloseableReference around until the image is not needed any more, see http://frescolib.org/docs/closeable-references.html
