Good Morning all ! 

As you might know, we are currently adding Amazon Device Messaging support to the UnifiedPush server. 
The server side has been PRed and it's now time to work on the client SDK.

once our java-adm is on maven central, I will take a look at the PR
 
As you probably know, the amazon devices :  the Kindle Fire (2nd and third generation), Fire Phone and FireTV are running FireOS which is basically a fork of Android OS. And since we have an Android Push SDK I start looking if we could reuse it.

First good news, is that since AGDroid 2.0, things has been nicely isolated and is open for extension. But there is still some refactoring to do, the "UPS Registration" flow/logic is still in the "gcm" package[1].

the package name shouldn't be the smallest concern :-) 

 
That logic should be moved one package level higher in a new Abstract class. 
In the end we will have a "gcm" package and a "adm" package (or project, see later in my questions)

+1
 

This way the ADM logic would be able to reuse that registration code. I started to play a bit with this refactoring here[2], disclaimer here, I'm not even sure that this code compiles, is just to give an idea. 

So before I go further,  some questions (mainly for our Android Gods ;)  ) : 

- Is this a good idea (reusing your SDK) ? I think yes, even if there is some time and effort needed for refactoring to make it completly generic.

sounds reasonable to me, to extend it and apply changes on a separate ADM-PUSH-SDK
 

- How do we build / package / deliver ?

gradle? or, what does Amazon do / prefer ? 
 
We probably want 2 distinct JAR/aar. We could use profile in Maven to only package one feature but that sounds a bit "messy".
What about having sub-projects, this way we would have aerogear-android-push and then : aerogear-android-push-gcm and aerogear-push-gcm.

Not sure I get that, but do you mean "aerogear-android-push"
- aerogear-android-push-gcm
- aerogear-android-push-adm

sounds reasonable
No it isn't.  For starters it will break the 2.0 API and require a 3.0 API release. 
 

- The registration flow for ADM[3] (so device <-> Amazon's server) is a bit different thant the GCM one
, it's the same interface that receive the registration event and the push notification events. We have to check how this fit with the current architecture of android-push.

Other challenge will be shipping ADM jar, since this one is on Maven and must be downloaded manually but that is for later ;)

not sure, why do we need to ship it? what's the license? Why do I need a manual download from maven ? Not following here
Amazon's SDK is a giant zip bundle.  We will need to find a way to package it into the local maven repo. 
 Yeah it's a nightmare. You can get this ZIP only from their developer's portal. Once unzipped, you have to dig some folder before finding the ADM jar (the only one that we need)

They do publish some things to central, but it looks like that is their AWS APIs but not ADM.
Yep, I checked as well and it's only for AWS stuff :(
