title: Is it needed to call Bitmap.recycle() after used (in Android)?
body: <p>According to Android Reference Document of <code>Bitmap.recycle()</code>:</p>
  
  <blockquote>
    <p>Free the native object associated with this bitmap, and clear the
    reference to the pixel data. This will not free the pixel data
    synchronously; it simply allows it to be garbage collected if there
    are no other references. The bitmap is marked as "dead", meaning it
    will throw an exception if getPixels() or setPixels() is called, and
    will draw nothing. This operation cannot be reversed, so it should
    only be called if you are sure there are no further uses for the
    bitmap. <strong>This is an advanced call, and normally need not be called,
    since the normal GC process will free up this memory when there are no
    more references to this bitmap.</strong></p>
  </blockquote>
  
  <p>But, many books I read suggest to free memory by calling Bitmap.recycle() once make sure no longer need it.</p>
  
  <p>It make me confused: Is it needed to call <code>Bitmap.recycle()</code> after used?</p>
