Why does Arcgis Runtime for Android download of Preplanned Workflow fail because of unreasonable memory allocations?

[NathanMellor]

I have some ready preplanned map areas that I decided to try with the runtime 100.2.1 before I do this on a larger scale. 

I below captured the layer errors below upon failure. 

Caused by: java.lang.OutOfMemoryError: Failed to allocate a 710258114 byte allocation with 16777216 free bytes and 40MB until OOM

Why in the world would you be trying to allocate 710 Megabytes?

On a MOBILE DEVICE, no less?

I can only guess that you are trying to allocate enough memory for the entire file. 

Why would that ever be a good idea?

The destination for the file is a folder on disk. 

BUFFERING is a fairly standard practice for downloading a file from disk. There is no way you need 710 megabytes of memory to download a 710 megabyte file. 

You are advertising this preplanned workflow, and I was attracted to all of the benefits.

But it obviously isn't well coded or well tested. 

Please fix it or provide some workaround, so I don't regret the trust I have placed in ESRI for the 10th time.

To add to that, the OnDemand Workflow doesn't work either, for other reasons I don't understand. 

Error is: Token required.

Hmm, the documentation doesn't say a word about tokens. It appears that they are used internally, so It certainly isn't my fault if it doesn't have a token.

Still not working.

I have seen this behavior consistently.

I have been in contact with ESRI support, but they are still in denial about this.
