if (!dirent.isDir || dirent.contents == null) {
// It's not a directory, or there's nothing in it
mErrorMsg = "File or empty directory";
return false;
}
此代码无效DownloadRandomPicture.java
有谁知道如何解决它?

如果我们正在使用
final static private AccessType ACCESS_TYPE = AccessType.DROPBOX;
我们应该
Entry dirent = mApi.metadata(mPath, 1000, null, false, null);
但如果我们正在使用
final static private AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
我们应该使用
Entry dirent = mApi.metadata(mPath, 1000, null, true, null);
差异在于dirent的布尔值

试试这个,它对你有用......
try
{
Entry existingEntry = mApi.metadata("/" + SavedProperties.selectedAddress , 1, null, false, null);
if(existingEntry.isDir)
{
Log.d(TAG, "Folder exists : " + existingEntry.fileName());
uploadPictures("/"+SavedProperties.selectedAddress + "/");
}
}
catch (DropboxException e)
{
Log.d(TAG,"Folder does not exist..." + e.fillInStackTrace());
try
{
Entry createFolder = mApi.createFolder("/"+SavedProperties.selectedAddress);
Log.d(TAG,"Folder created..." + createFolder.rev);
uploadPictures("/"+SavedProperties.selectedAddress + "/");
}
catch (DropboxException e1)
{
Log.d(TAG,"Create Folder DropboxException : " + e1.fillInStackTrace() );
}
}
