Paypal integration for android deprecated

When I tried to find official documentation for android for integrating paypal express, I found
Important: PayPal Mobile SDKs are now Deprecated and only existing integrations are supported. For all new integrations, use Braintree Direct or Express Checkout'.
I couldn't find any android documentation in the recommended pages as well. Is it something like we have to use the REST API provided by them in android as well?
Please guide me how I can implement paypal in android.

Did you look at the Braintree SDK? It will tie PayPal, direct credit card processing, Venmo, Apple and Google Pay in a single integration. That's what I would recommend.
Specifically, you should use their Drop In UI. Here's a guide for Android integration with Braintree.

pulling shipping information from android PayPal sdk

Does the new native PayPal sdk for android have the ability to pull shipping information to give to the merchant? The sample code provided on the PayPal site will process cards etc, but it appears to me that the api only provides payment confirmation. What good is this api if you don't know where to send your product?
Anyone know how to do this?

Jeff from PayPal at your service. The PayPal Android SDK does not support shipping addresses just yet. Your feedback is heard, and we plan to add the feature as soon we can!

Android : Payment Processing

I've referred lot of things for payment processing system to android app. It proviedes Paypal's SDK as best to do. But, i've little confusion in there for below image -
What's the difference between these two - Mobile Express Checkout Library & Mobile Payment Libraries. And, which one will i choose to do the payment processing for android app. Anyone please, explain with brief explanation please. Thanks in Advance.

I hope this will help you :
Mobile Payment Libraries (MPL): Add in-app payments by just adding a
Pay with PayPal button to your iOS or Android app. PayPal’s library
will display an in-app UI to ask the buyer to log in and complete the
payment. It's the quickest way to add payments into your app, and you
can do it without having back-end services running.
Mobile Express Checkout Library (MECL): If you want the PayPal
checkout flow to be in a browser or webview, you can use our Mobile
Express Checkout Library. This is useful if you already have a express
checkout integration completed for your website or if app store
policies require you to complete your checkout flow in a browser. This
library will help you integrate the mobile web flow into your app.
I got this information from here.

Android In-app purchases with Phonegap

Is there any way to implement Android In-app purchases with Phonegap? I can't find any information abt this issue. For example I can do IAP on iOS using InAppPurchaseManager Phonegap plugin. But there are no relevant plugins for Android.
And if it's impossible for some reason can you suggest any other way to implement instant(or renewable) payments for Phonegap Android app. I know there is a PayPal API for Android but I can't use it because of Phonegap...
The only way I can see is to use PayPal API for web-sites (and I have website where I can implement it) but I believe it's a bad user experience.
Please Help! Any suggestions!?
Thanks.

A partner and I just open sourced Android PayPal PhoneGap plugin and did a pull request to incorporate it into the PhoneGap plugin repository.
The plugin and instructions are now available on a branch here in this fork.
Let us know if you have any feedback.

PayPal recently released a PhoneGap plugin for Android, which is actively supported by PayPal.
