Serving audio / video / image files to mobile using Google App Engine Mobile Backend

Question

So, I'm new to Google App Engine and I'm trying to use it to setup my mobile backend. What I want to do is to be able to put up some songs on the backend and be able to GET those files as a request in my android app. I've followed a few steps that I found online:

1) Deployed a backend for my app with a unique ID

2) Tried the example app that was provided and was able to connect and send data to my app's backend:

However, I still can't figure out how to do what I want which is to put files on the backend and be able to request them from the app and have them show up (e.g a streaming a song on my app). I would really appreciate any help here. Again keep in mind that I'm very new to the Google App Engine. Thanks in advance!

MBS is primarily to let you store and access your data in datastore, directly from devices, without necessarily having your own server process.

For a streaming service, you will need to have a server process. Best way is to store files with full control, is to use BlobStore and use the BlobReader to read and serve in chunks.

More convenient way, but with less control is to store in cloud-storage and serve directly to client with cloud-storage URI, without streaming through your server, in which case, you do not need a server process.
