I am slightly confused with the Firebase client library that is available for Java. In the documentation, it says that the library should be used on the server. Recently, I came across Google App Engine. A PaaS service that allows application code to be put in the cloud.
Could I write the server code using the Firebase client library and deploy that as application code on Google App Engine? That way my application could connect with Firebase through the App engine.
I am asking this questions from the perspective of creating a Java application; the same libraries available for Android are not available for Java desktop applications. The only library that can be used in Java is the server library.
Thank you.
That is possible with the firebase-server-sdk.
You find an example deploying a servlet to appengine and access firebase from within the servlet here: https://cloud.google.com/solutions/mobile/firebase-app-engine-android-studio
Just skip the android stuff and scroll down to MyServlet source code.
But be aware of the scaling setting you need to use firebase on app engine.
I am seeking information about using Firebase (as database) for Java. Is this possible along with hosting of Java (using Spring framework) project over Firebase hosting.
It is possible. Use Google App Engine an environment for running application code in the cloud; Platform as a service (PaaS).
Below is description how make to make basic example.
In the this tutorial, you'll learn how to:
Create a backend service running on App Engine using Android Studio.
Connect the backend service to your data in Firebase.
The sample app stores a to-do list in Firebase, which automatically synchronizes the data across devices, and then uses backend logic running on App Engine to send out daily reminder emails:

By connecting App Engine to a Firebase database, you can perform complex logic on data without having to manage synchronization and updates; Firebase handles that for you.
No. Firebase offers hosting for static assets only.
The Google Cloud Run seems is most suitable for what you want.
Consider to check the documentation and pricing. Like firebase, cloud run also has a free tier that can help you develop your app with no costs.
The cloud run supports several programming languages including Java.
Once created the service you can try to connect to your firebase project...

I'm creating a network based android application. So
1) I've installed Google App Engine Plugin in eclipse IDE and start developing a network based android applications where all information of customers are stored in GAE Datastore.
2) I've created a new Web-Application and stored Entities in datastore. Can i retrieve those values and show in my android application and add new details in from my application to GAE Datastore.
Please Help Me, I'm new to Web Service, SOAP, REST, JSON etc.
Can anyone tell me a simple method to store and fetch values from Cloud DB to Android App.
There are two apparent options:
Use Cloud Endpoints. They are proprietary and not my favourite. Also they are only available for Android, iOS and JS.
Use web services, my favourite would be JAX-RS, specifically RESTEasy+Jackson. See this GAE example and simple Android client.
I apologise for the very general question but I'm looking for some advice. I have two products that I have created for a project. An android app and a website service. I want the android app to be able to connect to a PostgreSQL database in order to authenticate user login and submit a small amount of data.
The data on the PostgreSQL database will then be produced on the website. Simples!
I'm wondering if there are some tutorials or discussions that provide a simple solution to this. I've looked at loads of forums which mention using a lot of complicated protocols, frameworks, etc.
I'm just looking for some nice efficient android examples on how to achieve this.
Any advice would be appreciated.
You should not worry about android and PostgreSQL communication because they won't communicate directly.
All what you need is a simple HTTP communication between your android and the web service to send and receive information (e.g. credential for authentication)
Your web service should take care of storing and retrieving data from the database
What is the best way to access Google Documents (documents, spreasheets etc from Google Apps or Gmail) using Java on Google App Engine. We are using GWT on the client side.
Thanks,

The Google Data Client for Java suppose to work on the Google App Engine.
It gives you access to must of Google Apps Services.
Google has Google Client API which probably has a better support for OAuth2, json and support for the API discovery, but still The old API should work.
Read about Migrating To Google Api Java Client this should resolve any confusion you might have.
