Android API - listfolder returns nothing

nzmike

I have to admit here that I'm both new to Android and new to the DropBox API (but not new to development) so maybe I'm doing something wrong but I cannot get listFolder to return any files no matter what I try.

 

My code is below and the loop that gets the files is taken from the example API code. There is no issue conencting with the API but no matter what path I put in I either get nothing (if I use "") or an exception if use any other path.

 

One other thing I'm also confused about - once I've set up an app in the DropBox dashboard (say it's called MyTestApp) do I then need to create a folder of the same name in the root of my DropBox folder?  If not, where is the folder for the app to be found?  I am assuming using "" as the path is the same as saying DropBox/MyTestApp.  I have 5 files of mixed type in this folder but the code never returns anything.... can anyone help me out to get this working?

 

public class MainActivity extends AppCompatActivity {

private List<TestClass> filesList;

final static private String APP_KEY = "yyyyyyyyyyyy";
final static private String ACCESS_TOKEN = "xxxxxxxxxxx";

@Override
    protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

//I KNOW THIS IS NOT GOOD CODE BUT I JUST WANT TO GET THE listFolder WORKING
        //BEFORE MAKING A SEPERATE FUNCTION FOR THIS.
        StrictMode.ThreadPolicy policy = new
        StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

        DropboxClientFactory dbFactory = new DropboxClientFactory(ACCESS_TOKEN);
        DbxClientV2 client = dbFactory.getClient();

        //TestClass is just a simlpe class with an integer and a string
filesList =  new ArrayList<TestClass>();

try {
            ListFolderResult result = client.files().listFolder("");
while (true) {
for (Metadata metadata : result.getEntries()) {
                    System.out.println(metadata.getPathLower());   //Never prints anything
filesList.add(new TestClass(metadata.getPathLower()));
                }

if (!result.getHasMore()) {
break;
                }

                result = client.files().listFolderContinue(result.getCursor());
            }
        }
catch (DbxException ex)
        {
            System.out.println("EXCEPTION getting DropBox Files list: " + ex.getMessage());
        }
     }
}

Just registering an app (i.e., creating it on the App Console), does not automatically create the "app folder" in your account. The app folder is only created in the account once the app is "linked" to the account (i.e., when the user goes through the OAuth app authorization flow to authorize the app to connect to their account, or, for the account that owns the app, when you click the "Generate" button on the app's page on the App Console to get an access token for your app-account pair).

You don't need to delete or recreate any app or folder, nor do you need to make an API call to determine the path. (Apps with the app folder permission don't need to know the full path of the app folder. All paths in API calls made by apps with the app folder permission are automatically used relative to the app folder.)

I recommend going to https://www.dropbox.com/ to browse your account. Assuming your account is set to English, the app folder(s) will be inside a folder named "Apps".

There's an example Android app here:
