    copied!<p>I would like to use Android's system cache when downloading images as per these previous instructions: <a href="https://stackoverflow.com/questions/1945201/android-image-cache/3893959#3893959">android system cache</a>. I was able to get the following code working but the log statements are telling me that the images are never being read from the cache. </p> <pre><code>try { //url = new URL("http://some.url.com/retrieve_image.php?user=" + username); URL url = new URL("http://some.url.com/prof_pics/b4fe7bdfa174ff372c9f26ce6f78f19c.png"); URLConnection connection = url.openConnection(); connection.setUseCaches(true); Object response = connection.getContent(); if (response instanceof Bitmap) { Log.i("CHAT", "this is a bitmap"); current_image.setImageBitmap((Bitmap) response); } else { Log.i("CHAT", "this is not a bitmap"); Log.i("CHAT", response.toString()); InputStream is = connection.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); current_image.setImageBitmap(BitmapFactory.decodeStream(bis)); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } </code></pre> <p>I have tried two different types of requests, one is to go through a PHP script that returns the image and another that is directly accessing the image file. I refresh the same image multiple times in a row and it never seems to get cached. For the direct image access, I get: </p> <pre><code>05-31 23:45:12.177 I/CHAT ( 2995): this is not a bitmap 05-31 23:45:12.177 I/CHAT ( 2995): org.apache.harmony.luni.internal.net.www.protocol.http.FixedLengthInputStream@40c1c660` </code></pre> <p>For the indirect image access, I consistently get:</p> <pre><code>05-31 23:45:14.550 I/CHAT ( 2995): this is not a bitmap 05-31 23:45:14.550 I/CHAT ( 2995): org.apache.harmony.luni.internal.net.www.protocol.http.ChunkedInputStream@40c02448 </code></pre>
