question

Hi there, Thanks for posting. Any more information would be appreciated. What are you actually trying to do? Feel free to post the code you're using and we will investigate to see what is going wrong. Thanks! Jamie

Thanks for Answering. I'm WhiteList completed ( Scope : read & write) also completed security profile settings. I tried nodelist. public static final String[] APP_CLOUD_SCOPES = { "profile", "clouddrive:read_all", "clouddrive:write" }; ListNodesRequest listNodesRequest = new ListNodesRequest(); listNodesRequest.setFilters("isRoot:true"); ListNodesResponse listNodesResponse = mAmazonCloudDriveClient.listNodes(listNodesRequest); Please confirm. ===================== log ========================= D/com.amazon.identity.auth.device.endpoint.TokenVendor.PII?

Thanks for your reply but some additional info is required. It appears that you are creating an array and then making a request. There is a bit of configuration missing in between that should help answer the question. The log output knows the app_id and the list of scopes, but the code sample never shows them being given as parameters to anything.

Hi Ross ~! I'm asking information under review. public static final String[] APP_CLOUD_SCOPES = { "profile", "clouddrive:read_all", "clouddrive:write" }; public static synchronized AmazonCloudDriveClient getAmazonCloudDriveClientInstance(Context context) { if ( sAmazonCloudDriveClient == null ) { sAmazonCloudDriveClient = new AmazonCloudDriveClient( new AccountConfiguration( new AmazonAuthorizationConnectionFactory( getAmazonAuthorizationManagerInstance(context), ACDConstants.APP_CLOUD_SCOPES)), new ClientConfiguration(ACDConstants.USER_AGENT)); } return sAmazonCloudDriveClient; } public int getFileList(final String path, final ArrayList fileList) { mAmazonCloudDriveClient = UserState.getAmazonCloudDriveClientInstance(context); ListNodesRequest listNodesRequest = new ListNodesRequest(); if ( path.equals("/") ) { listNodesRequest.setFilters("isRoot:true"); } try { ListNodesResponse listNodesResponse = mAmazonCloudDriveClient.listNodes(listNodesRequest); List nodes = listNodesResponse.getData(); FileInfoParcel fileInfoParcel; for (Node node : nodes) { FileInfo fileInfo = new FileInfo(); fileInfoParcel = new FileInfoParcel(); fileInfo.id = node.getId(); fileInfo.isFolder = node.getKind().equals(NodeKind.FOLDER) ? true : false; fileInfo.parentPath = path; fileInfo.name = node.getName(); fileInfo.size = node.getContentProperties().getSize(); fileInfo.updateTime = getTimeInMillis(node.getModifiedDate()); fileInfoParcel.setFileInfo(fileInfo); fileList.add(fileInfoParcel); } } catch (CloudDriveException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } }

Thanks for your reply and I am wondering if I can get additional answers as soon as possible.. (I am quite urgent...T_T) Thanks :)

From this code snippet we cannot tell if you are setting up the clientId and clientSecret correctly. Before making the call to CDS, the SDK needs to call LWA to fetch the token. It is possible that the call to LWA is failing and no token is being returned.
