Entry dirent = mApi.metadata(mPath, 1000, null, true, null);
 if (!dirent.isDir || dirent.contents == null) {
                    // It's not a directory, or there's nothing in it
                    mErrorMsg = "File or empty directory";

this code is not working at DownloadRandomPicture.java anyone know how to fix it?

Answer 1

If we are using

final static private AccessType ACCESS_TYPE = AccessType.DROPBOX;

we should

Entry dirent = mApi.metadata(mPath, 1000, null, false, null);

but if we are using

final static private AccessType ACCESS_TYPE = AccessType.APP_FOLDER;

we should use

Entry dirent = mApi.metadata(mPath, 1000, null, true, null);     

The difference is at the boolean at the dirent
