onCompleted is not called

• Android Upload Service version (e.g. 3.0.3):
• Android version and API version (e.g. 6.0.1 API 23):

I expect the onCompleted callback to be called when the upload is finished But it’s not called

This is my request code:

final String uploadId =
             new net.gotev.uploadservice.MultipartUploadRequest(getApplicationContext(), "https://www.motolife.bg/post_avatar.php")
             .addFileToUpload(filename, "photo")
             .addParameter("parameter","value")
             .setDelegate(new net.gotev.uploadservice.UploadStatusDelegate() {
               @Override
               public void onProgress(net.gotev.uploadservice.UploadInfo uploadInfo) {
                 Log.e("gotev","onProgress eltstr="+uploadInfo.getElapsedTimeString()+" elt="+uploadInfo.getElapsedTime()+" ratestr="+
                 uploadInfo.getUploadRateString()+" prc="+uploadInfo.getProgressPercent()+" tb="+uploadInfo.getTotalBytes()+" ub="+uploadInfo.getUploadedBytes());
               }
               @Override
               public void onError(net.gotev.uploadservice.UploadInfo uploadInfo, Exception e) {
                 Log.e("gotev","onError "+e.getMessage() + e.getStackTrace());
               }
               @Override
               public void onCompleted(net.gotev.uploadservice.UploadInfo uploadInfo, net.gotev.uploadservice.ServerResponse serverResponse) {
                 Log.e("gotev","onCompleted "+serverResponse.getHttpCode()+" "+serverResponse.getBodyAsString());
               }
               @Override
               public void onCancelled(net.gotev.uploadservice.UploadInfo uploadInfo) {
                 Log.e("gotev","onCancelled "+uploadInfo);
               }
             }).startUpload();

This is my library initialization code

net.gotev.uploadservice.UploadService.NAMESPACE = bg.motolife.app.BuildConfig.APPLICATION_ID;

And this is my logcat output

08-19 19:31:21.649 1706-1706/bg.motolife.app E/gotev: uploadId=7e9235a9-de5a-4ead-8e2f-93ca25f30b20

                                                      {"st":0}

The request is successfully received by the server. But there is now output from the onCompleted callback

Updated the Monitoring upload status wiki page:

The recommended way to use delegates inside Activities or Services is to implement the UploadStatusDelegate interface in your Activities or Services instead of using the anonymous inner class, to prevent variable out of scope problems.

Please make use of markdown syntax to improve readability the next time, as I’ve noted in the asking for help wiki page. I’ve done that for you this time in your posts.

Made some tests using the node.js demo server and the demo app provided in the examples, and this is what I get in the LogCat:

I/UploadServiceDemo: ID 27a37309-dde3-47cf-8f89-cc223d4fb767: completed in 0s at 0,00 Kbit/s. Response code: 200, body:[Upload Ok!]

So those CR and LF characters are added by your PHP server-side script in the response. Here you can see the code which is being executed in the onCompleted method. If you dump network traffic I’m pretty sure you will see CR and LF at the beginning of the response body coming from your server.

[andsh]

To ensure the server response encoding I’ve modified the PHP script the following way: header(‘Content-Type: application/json; charset=utf-8’); echo utf8_encode(json_encode(array(“st”=>0)));

On the client side in the onCompleted method I inserted the following code int code = serverResponse.getHttpCode(); Log.e(“gotev”, “onCompleted3 " + code); byte[] ba = serverResponse.getBody(); for (int j=0; j<ba.length; j++) { Log.e(“byte”,String.format(”%02X ", ba[j])); } String str2 = new String(ba, Charset.forName(“UTF8”)); Log.e(“gotev”, "strs equ= " + resps.equals(str2)); JSONObject jo = new JSONObject(resps); int st = jo.getInt(“st”); Log.e(“gotev”, “onCompleted5 st=” + st);

And I’ve got the following in the Logcat in my Android Studio 08-20 12:13:50.999 20111-20111/bg.motolife.app E/gotev: onCompleted3 200 {“st”:0} 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 0D 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 0A 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 7B 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 22 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 73 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 74 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 22 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 3A 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 30 08-20 12:13:51.000 20111-20111/bg.motolife.app E/byte: 7D 08-20 12:13:51.000 20111-20111/bg.motolife.app E/gotev: strs equ= true 08-20 12:13:51.001 20111-20111/bg.motolife.app E/gotev: onCompleted5 st=0

See, in the second string i don’t see any string header because of new line and carriage return characters in the string And then In the byte loop we see first 2 bytes are exactly line_feed and carriage_return

From where are these two bytes in the beginning of the serverResponse?
