Can App Inventor convert Image to Byte Array

[Devan Spence]

I'm working with an API linked to web service and they require a byte array for all images being uploaded to their servers via POST.  Is there a way to convert images to byte arrays using App Inventor or a service/activity accessible in App Inventor?  Any help or input would be a huge help.

there is no such block available in MIT App Inventor

is there any documentation about that API? can you provide a link?

you probably could write your own extension and create a block yourself...

more information about how to create an extension see here https://groups.google.com/d/msg/mitappinventortest/Ip2AX036d0U/5NJlAEbFCgAJ

however that will be more advanced and will require some Java skills...

Here is a link to the API documentation:

https://www.methodintegration.com/documentation/MethodAPIv2_0_Documentation.pdf

I'm working under the MethodAPIUpdateFile section.

I assumed it would take a custom extension but I wanted to double check first.

One thing to consider is that Images could be large files and it may impact app performance.

I agree.  I'm not a fan of their requirement for byte arrays.
