UPDATE : 10/12/2012
After making with images:
WeakHashMap<Bitmap, WeakReference<Bitmap>> objReferenciaDebilBitmaps;
Bitmap imagen = datossss.getImagen();
objreCReferencias.RegristrarReferenciaDebilBitmap(imagen, objReferenciaDebilBitmaps);
my class Creferencias
public class CReferencias {
public CReferencias(){
}
public void RegristrarReferenciaDebilBitmap(Bitmap img, WeakHashMap<Bitmap, WeakReference<Bitmap>> objReferenciaDebilBitmaps){
WeakReference<Bitmap> objrererencia1 = new WeakReference<Bitmap>(img);
objReferenciaDebilBitmaps.put(img, objrererencia1);
}
After using this every time I do I create an Image, I do not know if it's the right way to use weak references to the bitmap,
but still gives me the problem sigiente
this is my logcat

that's what I'm doing wrong? I might say, as is the proper way to use weak references for all images and are deleted when I do not need?
If you are using bitmaps in your app, don't forget to call bmp.recycle() as GC in android cannot recycle bitmaps (for < Android v4.0, From 4.0 onwards, bitmaps are part of dvm). Also see my answer on same problem. I have addressed many answers, it will definitely solve your problem.
bitmap size exceeds Vm budget error android
