POCheck progress for Upload & Download (Google Drive API for Android or Java)

copied!<p>How to check the progress of an upload that use GoogleDrive API?</p> <p>The <strong><em>service.files().insert(body, mediaContent).execute();</em></strong> only return a <strong><em>file</em></strong> which we can check if the file has upload completely.</p> <p>But I need to check the progress in real time(at least each second or so), anyway to do it?</p> <p>And for download part, I think we can manually compare how many bytes we have already read from the inputstream to the total filesize, then calculate the current progress.</p> <p>But is this the correct way? Or there is other better way of checking progress?</p> <pre><code>private void saveFileToDrive() { Thread t = new Thread(new Runnable() { @Override public void run() { try { // File's binary content java.io.File fileContent = new java.io.File(fileUri.getPath()); FileContent mediaContent = new FileContent("image/jpeg", fileContent); // File's metadata. File body = new File(); body.setTitle(fileContent.getName()); body.setMimeType("image/jpeg"); File file = service.files().insert(body, mediaContent).execute(); if (file != null) { showToast("Photo uploaded: " + file.getTitle()); //startCameraIntent(); } } catch (UserRecoverableAuthIOException e) { startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION); } catch (IOException e) { e.printStackTrace(); } } }); t.start(); } </code></pre> <p>EDITED: Using this code <a href="http://code.google.com/p/google-api-java-client/source/browse/drive-cmdline-sample/src/main/java/com/google/api/services/samples/drive/cmdline/DriveSample.java?repo=samples&name=based-on-1.12&r=08555cd2a27be66dc97505e15c60853f47d84b5a" rel="noreferrer">http://code.google.com/p/google-api-java-client/source/browse/drive-cmdline-sample/src/main/java/com/google/api/services/samples/drive/cmdline/DriveSample.java?repo=samples&name=based-on-1.12&r=08555cd2a27be66dc97505e15c60853f47d84b5a</a></p> <p>I am able to get some progress now if I am using <strong><em>resumable upload</em></strong>, I set chunksize to 1MB. BUT there are 2 problems now.</p> <p>1) The resumable upload is much slower than single upload, because it stop many times in between, only sending 1MB each time.<br> If I set chunksize to higher, then it wont show progress at all for smaller file.<br> So, progress in resumable upload is not what I actually want. I want progress in single upload.</p> <p>2) If I set chunksize about 1MB, my upload always <strong>fail</strong> at about 70% for a normal 10MB file.<br> If I set chunksize to 10MB then it will success, but I wont see any progress.</p> <pre><code>Drive.Files.Insert insert = service.files().insert(body, mediaContent); MediaHttpUploader uploader = insert.getMediaHttpUploader(); uploader.setDirectUploadEnabled(false); uploader.setChunkSize(10*1024*1024); // previously I am using 1000000 thats why it won't work uploader.setProgressListener(new FileUploadProgressListener()); com.google.api.services.drive.model.File f = insert.execute(); </code></pre> <p>LogCat Error:</p> <pre><code>11-27 19:23:26.927: D/FileUploadProgressListener(11527): Upload is In Progress: 0.5235538030501893 11-27 19:23:33.692: D/FileUploadProgressListener(11527): Upload is In Progress: 0.56095050326806 11-27 19:23:38.294: D/FileUploadProgressListener(11527): Upload is In Progress: 0.5983472034859306 11-27 19:23:50.583: D/FileUploadProgressListener(11527): Upload is In Progress: 0.6357439037038013 11-27 19:23:55.091: D/FileUploadProgressListener(11527): Upload is In Progress: 0.673140603921672 11-27 19:24:05.130: D/FileUploadProgressListener(11527): Upload is In Progress: 0.7105373041395426 11-27 19:24:17.005: D/FileUploadProgressListener(11527): Upload is In Progress: 0.7479340043574133 11-27 19:24:28.888: D/FileUploadProgressListener(11527): Upload is In Progress: 0.785330704575284 11-27 19:24:28.896: W/HttpTransport(11527): exception thrown while executing request 11-27 19:24:28.896: W/HttpTransport(11527): java.io.IOException: unexpected end of stream 11-27 19:24:28.896: W/HttpTransport(11527): at libcore.net.http.FixedLengthOutputStream.close(FixedLengthOutputStream.java:58) 11-27 19:24:28.896: W/HttpTransport(11527): at com.google.api.client.http.javanet.NetHttpRequest.execute(NetHttpRequest.java:88) 11-27 19:24:28.896: W/HttpTransport(11527): at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:980) 11-27 19:24:28.896: W/HttpTransport(11527): at com.google.api.client.googleapis.media.MediaHttpUploader.upload(MediaHttpUploader.java:293) 11-27 19:24:28.896: W/HttpTransport(11527): at com.google.api.services.drive.Drive$Files$Insert.executeUnparsed(Drive.java:309) 11-27 19:24:28.896: W/HttpTransport(11527): at com.google.api.services.drive.Drive$Files$Insert.execute(Drive.java:331) </code></pre>
