Per Box example easy way to get user's root folder using below code
http://opensource.box.com/box-java-sdk/
BoxAPIConnection api = new BoxAPIConnection("your-developer-token");
BoxFolder rootFolder = BoxFolder.getRootFolder(api);
for (BoxItem.Info itemInfo : rootFolder) {
System.out.format("[%d] %s\n", itemInfo.getID(), itemInfo.getName());
}
But if i need to access someone else info using As-user, I'm unable to use BOX SDK classes (BoxFolder, BoxFile, BoxUser...) and need to get the data only from JSON directly like below. If i do so, i'm loosing the latest features added in the new SDK. Is it the best way? How about the performance? Is there any alternative way available?
url= new URL("https://api.box.com/2.0/folders/0");
BoxAPIRequest request = new BoxAPIRequest(api,url,"GET");
request.addHeader("As-User", "12345678");
BoxJSONResponse response = (BoxJSONResponse) request.send();
JsonObject responseJSON = JsonObject.readFrom(response.getJSON());
Later get the folder properties using JsonObject / JsonArray. If i need the folder items, i need to loop the JsonArray like below
JsonArray entries = responseJSON.get("entries").asArray();
for (JsonValue entry : entries)
{ ....}
