    copied!<p>I am having a problem releasing memory. I have a <code>Hashmap</code> in which I am adding a <code>Bitmap</code> , and the number of bitmaps is quite large. For this reason, I am getting <code>OutOfMemoryError</code>. So for this I have decided to release <code>Bitmap</code> which is least used from <code>Collection</code>, on memory crunch or system getting low on heap memory.</p> <p>For getting the current memory available, I used "<strong>ActivityManager.MemoryInfo.availMem</strong>", but it gives the total RAM size memory, not available heap memory. And I found that this <strong>memory is not getting updated on releasing</strong> Bitmap from the collection.</p> <p>Then I have used these three methods:</p> <pre><code>Debug.getNativeHeapAllocatedSize() Debug.getNativeHeapFreeSize() Debug.getNativeHeapSize() </code></pre> <p>but I found the NativeHeapSize goes on increasing up to some certain level, say 16&nbsp;MB, changing after that an <code>OutOfMemoryError</code> occur. In this also, I found that the <code>NativeHeapAllocatedSize</code> and <code>getNativeHeapSize</code> is not decreasing on releasing <code>Bitmap</code> from <code>Collection</code>.</p> <p>How do I solve this problem?</p> <p>My problem is I want to calculate the maximum available application memory allocated and currently available memory, such that if the currently available memory goes beyond the threshold memory I will release some <code>Bitmap</code> from the collection and <a href="http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29" rel="nofollow">garbage collection</a> will reclaim the memory and free it without generating an error.</p>
