I want to download file from Data & Storage >> Files. I use method "download" of AsyncFile, but it needs MetaData. Therefore iI try to download MetaData using method "downloadMetaData" which needs ID of file. After using this method, App crasches.

How correctly to download the file? Thaks.

======================================

I use this code for download metadata to download image.

client.file().downloadMetaData("518fb003a6b1878c340040c8", new KinveyClientCallback()

{

@Override

public void onSuccess(Void arg0) { }

@Override

public void onFailure(Throwable arg0) { }



});

Hey,



I just did some looking into this, and it looks like this is a bug-- thanks for reporting it, and I will get a new version of the android library out soon with the fix.



In the meantime, since you just want to download a file, you can create a `FileMetaData` object inline and send it over to the download method.



For example:



FileMetaData myMetaData = new FileMetaData("518fb003a6b1878c340040c8");

client.file().download(myMetaData, myOutputStream, new DownloaderProgressListener() { ... });
