title: Android loading many images into gridview
body: <p>In one section of my app , I m showing images to 1024+ websites inside a gridview. When the images are not present on the devices they are downloaded with an async task and the image is saved in the data folder. The grid view has a section indexer, adapter and fast scroll associated with it.</p>
  
  <p>However I have noticed that the app becomes really slow when I try to fast scroll to different positions in the app. A solution <a href="https://stackoverflow.com/questions/541966/how-do-i-do-a-lazy-load-of-images-in-listview"><code>\[here\]\[1\]</code></a> hints implementing a hashmap to store images. The total size of the images I have are around .3mb . Will storing the bitmap in the map help speed up the app ?</p>
