[Android] CMIS connection exception

[sbalajis]

Hi, I am currently developing an android app using OpenCMIS to download files from alfresco hosted on the AWS. I am trying to do concurrent downloads. Say, One one tab, I click a button to download a file. When the download is happening , I go to another tab and click an image view to download it and display it on the server. This works fine on a normal WIFI connection(around 2mbps) but when I try to do the above activities from the app on a mobile connection(2G/3G) connection, I get the following error. I am not sure if this is due to a slow internet connection. If so is there a work around? Is there a better way to do concurrent activities in a single session.

Please let me know if the information provided is insufficient. Thanks for your help.
I attached a log file showing the error, but was not displayed in the preview. So I pasted the chunk of the error here.

The code that is causing error:

Folder folder = (Folder)o;                     
String folderName = folder.getName();
Log.d(TAG,folderName);
ItemIterable<CmisObject>photos = folder.getChildren();
if (photos.getTotalNumItems() > 0) 
   for (CmisObject p : photos){
   if (p.getBaseTypeId().equals(BaseTypeId.CMIS_DOCUMENT)){
   Document photo = (Document) p;
   String photoName = photo.getName();
   Log.d(TAG,photoName);
   ImageFolder imageFolder = new ImageFolder(folderName," ",photoName,,getContext());

Following is the error message

Aloah,

What version of opencmis do you use ?

Related to your log it seems the url is malformated. It terminated with an ":" character instead of nothing.

Hi Pascal, Thanks for your time.
I used opencmis for android client version 0.8.0. The URL was generated by the CMIS. Not sure what went wrong there.

Thanks

[jm_pascal]

Could you try with this version 0.8.0-alfresco-patched or eventually with the latest one from apache chemistry  CI

[sbalajis]

Thank You very much for your help. I will try with the latest from apache chemistry CI and will update how it worked.

Hi, I tried with the latest version of the opencmis android client but I am having the same problem. Again, it works with a tablet connected to WIFI but it is giving problem on a mobile phone on a 2G/3G connection.Please let me know if you would need any other details. Thanks.
