title: what do we mean by Clamp target GC heap from 55.234MB to 48.000MB?
body: <p>I'm using ImageLoader in one of ma listview to display images from URL. While scrolling the list, app didn't response. I checked logcat and got this log report <a href="http://pastebin.com/Zfsk7r9X" rel="noreferrer">http://pastebin.com/Zfsk7r9X</a>. In this log, "Clamp target GC heap from 55.234MB to 48.00MB" is shown. How can I avoid this memory issue. I've done System.GC() in ImageLoader class.
  decodeFile() which i used is shown below</p>
  
  <pre><code>// decodes image and scales it to reduce memory consumption
  private Bitmap decodeFile(File f) {
      try {
  
          // decode image size
          BitmapFactory.Options o = new BitmapFactory.Options();
          o.inJustDecodeBounds = true;
          BitmapFactory.decodeStream(new FileInputStream(f), null, o);
  
          // Find the correct scale value. It should be the power of 2.
          final int REQUIRED_SIZE = 70;
          int width_tmp = o.outWidth, height_tmp = o.outHeight;
          int scale = 1;
          while (true) {
              if (width_tmp / 2 &lt; REQUIRED_SIZE
                      || height_tmp / 2 &lt; REQUIRED_SIZE)
                  break;
              width_tmp /= 2;
              height_tmp /= 2;
              scale *= 2;
          }
  
          // decode with inSampleSize
          BitmapFactory.Options o2 = new BitmapFactory.Options();
          o2.inSampleSize = scale;
          return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
      } catch (FileNotFoundException e) {
      }
      return null;
  }
