Does Firebase support C++ for Realtime Database? I can't seem to find any documentation about it.
If there is, can you please point me out on the documentation? Please.
Thanks!
Since 2.0 version of Firebase C++ SDK it provides bindings for Realtime Database.
Also, in 2.1 version from (9 dec of 2016) Google adds the Firebase Storage bindings.
It does support C++.
This link has the guidelines for implementation of Firebase Realtime Database in C++:
https://firebase.google.com/docs/database/cpp/start
The Firebase Realtime Database Test Application (testapp) demonstrates Firebase Realtime Database operations with the Firebase Realtime Database C++ SDK. The application has no user interface and simply logs actions it's performing to the console.

I have basic understanding of .net and chatbot.
I wanted to integrate Amazon lex in xamarin(ios, android)app. There seems to be no example or sample. I have created chatbot from AWS platform intent and slots.
Also I wanted to use database to get query return. Any sample to integrate AWS Lex with Xamarin app would be helpful.
As I understand from your question, you already have some implementation of chatbot made with AWS services, but you are having issue on integrating it to your xamarin application to be able to use it in IOS and Android devices.
For that purpose, there is AWS Mobile SDK which happens to support also xamarin.
From their link:
https://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/Welcome.html
I also did not find a Lex tutorial directly, but a very promising quote:
Supported AWS services currently include, but are not limited to [narrow list of services]
was on the same page. I looked around, found this text:
The AWS Mobile SDK for .NET and Xamarin also allows you to use most of the AWS services supported by the AWS SDK for .NET. The AWS services specific to mobile development are explained in this developer guide. For more information about the AWS SDK for .NET, see [a link]
clicked the link and ended here:
https://docs.aws.amazon.com/sdkfornet/v3/apidocs/Index.html
and under link AmazonLex -> AmazonLexClient there was something, you probably wanted to see:
Version Information
.NET Standard:
Supported in: 1.3
.NET Framework:
Supported in: 4.5, 4.0, 3.5
Portable Class Library:
Supported in: Windows Store Apps
Supported in: Windows Phone 8.1
Supported in: Xamarin Android
Supported in: Xamarin iOS (Unified)
Supported in: Xamarin.Forms
Those 3 last let me understand that whenever you setup Mobile SDK, you get access to AWS services in Xamarin, also Lex.
Steps to install on
https://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/setup.html
mainly contain steps on how to create xamarin app and get AWS account, most important is to install the AWS Mobile SDK for .NET and Xamarin and configure it. More detailed steps are under that link.
After that the process is to follow the instructions on:
https://aws.amazon.com/getting-started/projects/bots-just-got-better-net-toolkit-lex-lambda-cognito/module-one/
like pointed in comments. I suppose once you have access to any service via Mobile SDK, the wire up of Lex may go in similar steps and no special just xamarin tutorial is not needed anymore.
It seems you are looking for both architecture and sample code for implementing AWS Lex bot with .NET backend that can be integrated with iOS/Android Frontend.
You have multiple choices here to do it
Build both chat user interfaces in iOS and Android and integrate them AWS iOS & Android SDKs to utilize the AWS LEX bot.
Just implement a bot user interface in iOS and Android app and integrate it with a .NET backend that can utilize AWS .NET SDK to integrate with your LEX bot.
I would recommend the second approach as it will save you writing the LEX integration code twice both in Android and in iOS. In the second appraoch you will be able to write a single integration for AWS LEX in .NET and that can give a unified experience across the mobile devices(iOS/Android)
Now for the .NET based backend integration with AWS LEX bot.
If you are an experienced .NET developer and you know how will you host your code then only thing that you need is the .NET API reference for AWS LEX, which can be found here
https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/Lex/TLexClient.html
But if you are not sure how to write this integration code and also not sure how the deployment will look like then you can follow the below tutorial
Bots Just Got Better with .NET and the AWS Toolkit for Visual Studio
Also, find here the architecture form the above tutorial
there is no direct solution like Amazon Lex is supported by React-native. i confirmed with xamarin team as well as AWS service one of the member. direct integration not possible.
Hi All: I am supposed to provide Google calendar support on my C++ application running on Linux machine.
I came to know Google APIs Client Library for C++ is deprecated.So, I would like to know as to how I can provide calendar support in my Cpp application.
What steps should I follow and better if you redirect me to some URL ?
Thanks
I think you can use google calendar api using REST API.

how to use AWS RDS in flutter dart code?
I went through - this post
It says -
I work on the AWS SDK team. I am not aware of any plans to support Flutter at this point. I will take this to my team as a feature request and will post back
Should I do as suggested here?
Build your own service layer using HTTP, gRPC that talks to some backend service that provides access to a data store. You can do this with Express, Rails, CloudFunctions, etc.
You can either use dart code to do HTTP/gRPC, or use Platform channel to wrap dart code around native iOS and Android code of AWS official SDK.
On another note, I'm highly concerned when you connect directly from mobile (Flutter) to database (AWS RDS). Please be aware that anything on mobile app can be reversed engineer, and your database connection credential is not safe. It's recommended to have only backend proxy, or at least severless (such as AWS lambda function) connect directly to database (not mobile or web frontend). The only exception is with Firebase Realtime Database because it has seamless integration with Firebase Authentication
I am planning to use Firebase database and want to know how it fits in to the following scenario.
lets say I have a browser app, android app / iOS which uses Web Services to get / insert data, web services talks to the Data Base and returns data to the client.
This way I have to write code once in my web services and all the clients use that to retrieve and insert data to the database.
If I want to use Firebase, will I be following the same approach of having webservices between the client's and the Firebase DB.
I have done some sample Firebase examples where it it gets data from database directly without web services and in this approach we have to write our logic on each client (Web browser/ android app/ iOs app).
I have looked into this article
https://firebase.googleblog.com/2013/03/where-does-firebase-fit-in-your-app.html?showComment=1480073224245#c464815735109872173
The Pattern 2 has the server concept but that does not look appropriate in my scenario.
Can I have my web service and Firebase database and get data Synchronization capabilities.
Correct me if I am wrong and please suggest the approach I need to take.
Thank you for your valuable suggestions in advance.
Thanks & regards,

The article you link gives you the most common options for integrating Firebase into your app. Pattern 2 is the easiest way to use the Firebase Database and run your own server-side code:
In this model the Firebase Database sits between the app on the user's device and your back-end code. By using this model, you can still get all the benefits of the realtime synchronization, security rules and scalability, but also have back-end code that runs in a trusted environment.
Of course you can also go for a more traditional three-tier model, where your app server sites between the devices and the database. But in that case the Firebase database won't have direct interaction with your app anymore, so you'll have to take care of the realtime aspects of the synchronization (if you want those) in your own code.
I also recommend reading the Google Cloud documentation on using the Firebase Database and App Engine's Flexible Environments. The architecture described there is the same, but a bit more up-to-date:
Hi Guys
I am trying to create a web app to share docs with all editor features (just like google docs).
My main requirements for this app are as follows:
1. Should have all editor features (can be done using open office api, google docs api, Microsoft office web apps api)
2. Should be shared between multiple users and can be edited by multiple users and other sync features (can be done using google docs api, Microsoft office web apps)
3. Can save the document created and edited on my own/ custom server addr. (Which api can support this??? I know open office can support this)
Guys can you please suggest me one api which can be used to do all the above. Also please suggest if I am underestimating any API above regarding any functionality that i thing is not supported.
Thanks
King
What you are asking for is so complex it takes a Google to make a "in progress" version!
Can't you just use Google API? Its is free. Your only issue would be logging users via OAuth, 1 simple API
