So I'm developing a game for Android and I'm using Firebase for Authentication, to store user data, etc...
And now, I want to provide the user a way to share their score with their friends, so they can try to beat that score. I was thinking about sharing a dynamic link, and when the second user gets the link, the game would just start from that checkpoint.
But to do that, I would need to send a few data: the level Number, the first user's score, the first user's name.
I checked the documentation here and I saw that I can add some custom campaign parameters. But can I add those other parameters I need? If yes, How do I do it?
build Uri :
builder.scheme("https").authority("deepLink_from_firebase").appendQueryParameter("Param", Param_value).build();
and set that on setDeepLink()
To do this with Firebase, you would need to either encode all the custom data in the URL, or store it in your backend and use the URL as a key to retrieve the stored values. It's possible, but not as intuitive as you're hoping.
I would recommend investigating Branch.io (full disclosure: I am on the Branch team). The Branch service is free, does store an unlimited number of custom parameters with each link (exactly as you described), and interfaces perfectly with the other Firebase functions you are currently using. Branch links are used for this by many of the top apps in the world, including Airbnb, Pinterest, Tinder, and many others.

I've been working on an app which displays a list of websites when click on it will be redirected to webview in the app itself, I'm unable to find a way how to update the links dynamically without updating the app. So, If I want users to interact with new links the new links should automatically be updated in the app without update and in the webview too. Is it possible to do that?
You should use firebase remote config feature, which best fits in your case.
Firebase Remote Config is a cloud service that lets you change the
behavior and appearance of your app without requiring users to
download an app update.
Well to do that you first need to create a project in firebase console
In remote config feature you can add data in key-value pair. Like in this image:
I have added two key-value pair, as can add as much as you want. Now in the app side you have to add dependency:
implementation ‘com.google.firebase:firebase-config:11.8.0’
And to fetch the values which you have added in firebase, you can easily get those url but first you need to follow some steps to do that. You can check this simple tutorial.
Note: To get the values from firebase remote config you must need to click on publish changes button(Which you can see in above image top right corner).
You can store that link to a server and return that link when the app hits a certain API of that server. But for doing that, you need to setup a server, build a server application if you haven't already. Which is a lot of work for just storing a website link.
Another option could be, you can use services like http://bit . ly and create a custom link from that service, like http://bit . ly/my_specific_domain and use this link in your app. When you need to point to a different website, you can just update where http://bit . ly/my_specific_domain redirects to.
But you best bet would be to use Firebase Remote Config, which is both reliable and easy to implement, but that is already described in previous answer.
So I am currently struggling with 3 aspects related to email verification and setting it up in a way where when user clicks link in email he / she goes to app where I can then check if email was verified and show new view, aka dynamic linking?
1) I assume correct way to achieve this is by using User.sendEmailVerification(completion) ? I am struggling with setting up the completion step and would appreciate if someone could guide me through the process, also I am not 100% sure that this configures the deeplink, I might've miss-understood it.
2) If my assumption above is wrong, do I need to set up a dynamic link in firebase and then in my email templates section set it as url instead of default one i.e. myApp.firebaseapp.com/__/auth etc... If I do it this way I can retrieve token for verifying user, do I need to perform a call in app to post it to firebase somehow once I have it?
3) If I do need to use approach no.2, is there a way to use my own domain for dynamic links? i.e. I can set up small landing page with app-associate file for iOS and equivalent for Android, will this be enough? Do I miss out on any things like analytics here? Would you recommend for or against using custom domain for dynamic links?
https://firebase.google.com/docs/auth/ios/passing-state-in-email-actions is the primary guide for this.
user.sendEmailVerification(withActionCodeSettings:actionCodeSettings) - see the snippet in the doc above.
You need to support Dynamic Links, that is how the user is returned to your app.
Your own domain is not necessary.
I am currently using api.ai , to create agent to perform specific tasks, but one question i don't have answer to is , can i make it learn something while chatting , mean that i speak my name is 'John Cena' and she should store it and then whenever i ask her again bot should answer me that. i know there is a way to do it by logging into api.ai web and manually add entries , but it will not help, is there any work around programmatically or automatically ? the file i've been using to practice is given in github . and here is working DEMO
You basically need for your bot to "learn" facts. There are many different ways to achieve this, but recently the most common way is to arrange knowledge into Semantic "Triples" and store the knowledge into a Graph repository (like Neo4j, Titan, Spark Graph, etc). In your example, "my name is John Cena" would translate into a Triple like ("anubava","Name","John Cena"). That way, the next time you are logged in as anubhava and ask "What is my name?", it would translate into a Graph search that will return "John Cena". A word of caution, achieving this is not trivial and would require some significant amount of fine tuning. For more info, you can check here and here.
Finally, most complete solutions (that I know of), are Server Side solutions. If you want for the whole knowledge base to reside in your mobile device, you could probably use the resources there as inspiration, and build your own Linked Data repository using an embedded database.
Hope this helps. Good luck.
To store and recall the user's name, you'll need to set up a webhook with some basic data persistence capabilities. Any database or key-value store would work fine.
Here's the breakdown:
Implement webhook fulfillment for the intent that captures the user's name. The webhook should store the name along with a unique, identifying ID that you should supply from your front-end in either the sessionId or as a context parameter in your call to /query.
Implement webhook fulfillment for the intent that reads the user's name. The webhook should look up the name by ID and return a response that tells the user their name.
The high-level docs for writing a fulfillment webhook are here:
https://docs.api.ai/docs/webhook
I'm in course of developing an application, which basically is a quiz. I store all the questions on an external server, and fetch them as JSON files. I'd like to implement some Facebook features, most importantly the possibility of challenging other players. However, in order to compare the results, I'd like that other user to use the same set of questions in a current game, as I do - situation similar as in SongPop, where two players guess the same songs. I'm not sure though if it's possible for a standard Android app, not Facebook app like SongPop. I'm looking for a way of somehow sending a 'data pack' to him, containing the questions I have for the current challenge.
Create a Question Set which is a collection of Questions.
e.g. QuestionSet1 will contain Question2, Question4, Question5.
You can just send QuestionSet1 to the user being challenged. e.g. mysite.com/game/?questionsetid=1
On your server, if the url contains the parameter 'questionsetid', that meets you'll get the questions from the Question Set.
I already published an android app where you can see a list of specific objects and detailed informations about them. The list changes every day but some of the objects can appear again.
The application is communicating with a PHP server over HTTP and periodically pulls the list of objects.
I now plan to extend the app to make it possible to rate the objects and add a comment similar to how it is done in the android market. I'd like to avoid forcing the user to sign up for an account for being able to comment.
I see two problems:
The comment-system could be abused by spammers
A comment could be added from another system
So my questions are:
How to protect the system from spam?
How to authenticate the application with the server?
How do I limit the number of comments to one per user and object?
What about the androids device id? Is it unique enough to use it as identifier for the user?
Which other problems do you see?
2020 Commenting/Rating/Reviews Options
Since Socialize is out, here are a few options you can explore:
Build your own comment/rating implementation. Personally I love reddit and how it handles nested comments and ratings. Here's a library I found that implements it beautifully. Please note you'll need to tie this with a cloud-database. This is based on groupie. Article & implementation. Many ways to do this - https://stackoverflow.com/a/59472206/668240
Disqus - SDK's coming soon to iOS and Android.
BazaarVoice - commercial
Social Networks SDKs like Facebook, Twitter, etc. Personally I dislike this as we'll need to authenticate users with respective networks to use the APIs. It's like we are shipping off users of our apps to social networks. If you don't have a problem with that - then it might be for you
Legacy Option in 2014:
You can try out Socialize SDK which is open-source and a really good SDK for the rating and commenting you are looking for. It already has a well-functioning Commenting system built-in along with a 'like/love' facility and sharing to FB and Twitter. Each 'entity' (object in your case) can have metadata associated with it. So all you have to do is construct/use a rating widget, then send that rating with the entity attached to your object. To display your rating/comment is as simple as retrieving them from Socialize.
Each object (element from your app) should be associated with an entity which has a unique key in the form of a URL - sort of like a primary key to recognize your items. This entity can have meta-data - any data that you can insert on behalf of your object. Once you do that, you can retrieve that metadata any time you want.
I've been using Socialize for around a year now. They've matured over this period and are always aspiring to be the best at what they do.
Look at the Socialize Bar at the bottom. Its can be customized to your needs.
What's more - Socialize is free.
As for your questions:
There is comment moderation built into the Socialize Web Component
where you can filter out anything you feel is out of place.
Socialize allows you to authenticate through Facebook and Twitter.
Limiting to one comment per user can be achieved by using their User
and Comments API.
Socialize has both Anonymous authentication as well as Social A/c
authentication. I believe you can remove anonymous auth. So that
ensure that every user is authenticated before rating/commenting.
For authentication, you could use OpenID like StackOverflow does or Facebook authentication. Once you have them authentication, it shoud be easy to limit the number of comments to one per user per object. As far as spam, you could follow StackOverflow's model and allow users to vote comments up or down or flag as spam. Perhaps users with comments that have been voted up would have more power and be able to flag comments as spam.
You'll need some sort of rate limiting. I've used this one in this example before.
So you need a table with the user's ID and how many api calls they have left, and then when their last api call was. Then use the algorithm to update the values in the table every time a method is called.
Read through this, I think it should be possible to create an UUID for every case:
http://android-developers.blogspot.de/2011/03/identifying-app-installations.html
And then keep a hidden api key which is hard coded, or at least get's everytime calculated the same or in enigma style influenced by the time it is used. But you will be never be sure, that it won't be find out by crackers/hackers and maybe abused, you will always have this Problem.
Authenticate with the UUID of the user + api-key.
