    copied!<p>I am using <code>GZIPInputStream</code> to download PDF file. I want to show the download progress of the file on a UI button. But, I am not getting the actual size of the file, what I am getting is compressed size due to which I am unable to show the correct download progress. This download progress is exceeding <code>100</code> as the actual file size is greater than the compressed size of file.</p> <p>Header content of file from server: Following info I receive from server, from which I am using <code>content-length</code> which is giving compressed file size.</p> <pre><code>1.Connection 2.Content-Encoding 3.Content-length 4.Content-Type 5.Keep-Alive 6.Server 7.Date </code></pre> <p>Here is my code. Is there any way to get original size of file?</p> <pre><code>long fileLength = httpResponse.getEntity().getContentLength();// GZIPInputStream input = new GZIPInputStream(new BufferedInputStream( httpResponse.getEntity().getContent())); FileOutputStream output = new FileOutputStream(destinationFilePath); byte data[] = new byte[1024]; long total = 0; float percentage = 0; int count; currentDownloadingPercentage=0; while ((count = input.read(data)) != -1) { total += count; output.write(data, 0, count); // publishing the progress.... percentage = (float)total/(float)fileLength; percentage *= 100; if ((int)percentage &gt; (int)currentDownloadingPercentage) { currentDownloadingPercentage = percentage; Bundle resultData = new Bundle(); resultData.putBoolean(DOWNLOAD_FAILED, false); resultData.putInt(DOWNLOAD_PROGRESS ,(int)percentage); receiver.send(processID, resultData); resultData = null; } } </code></pre>
