Designed to help native mobile developers quickly and easily develop Firebase apps, FirebaseUI eliminates bloat in your application code by providing native bindings to common UI controls.

FirebaseUI adds support to quickly hook a Firebase database reference or query to a ListView, GridView, RecyclerView on Android or a UITableView or UICollectionView iOS.

Start by creating an Android Firebase project or iOS Firebase project then follow our Android or iOS quickstarts below.

Android Quickstart

On Android, add the latest version of FirebaseUI to your build.gradle:

compile 'com.firebase:firebase-ui:0.2.0'

Resync your project and you're ready to continue.

More information, including a more in-depth installation walkthrough, can be found on the FirebaseUI-Android README.

Once we've installed FirebaseUI, create a FirebaseListAdapter which binds a Firebase database reference or query to a ListAdapter and provides developers an easy way to populate ListView views with developer specified model objects (more information on using Java Objects is available in the docs).

Firebase.setAndroidContext(this);
Firebase ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");

mAdapter = new FirebaseListAdapter<ChatMessage>(this, ChatMessage.class, android.R.layout.two_line_list_item, ref) {
    @Override
    protected void populateView(View view, ChatMessage object) {
        /* Populate view with contents of the model object */
    }
};

mListView.setListAdapter(mAdapter);

If you want more examples, check out the Android README, or see our Android chat app example. The Javadoc is available here.

iOS Quickstart

On iOS, add the latest version of FirebaseUI to your podfile:

pod 'FirebaseUI', '~> 0.2.0'

If you're using Swift, make sure to add:

platform :ios, '8.0'
use_frameworks!

pod install, then open the generated .xcworkspace.

More information, including a more in-depth installation walkthrough, can be found on the FirebaseUI-iOS README.

Once we've installed FirebaseUI, create a FirebaseTableViewDataSource. This datasource will provide cells and the associated FDataSnapshots (or a custom model object, a feature in beta) to populate UITableViewCells, a custom subclass, or even a custom XIB.

Firebase *ref = [Firebase alloc] initWithUrl:@"https://<YOUR-FIREBASE-APP>.firebaseio.com/chat"];

self.dataSource = [[FirebaseTableViewDataSource alloc] initWithRef:ref
                                                        modelClass:[FDataSnapshot class]
                                                         cellClass:[UITableViewCell class]
                                               cellReuseIdentifier:@""
                                                              view:self.tableView];

[self.dataSource populateCellWithBlock:^void(UITableViewCell *__nonnull cell, FDataSnapshot *__nonnull snap) {
    /* Populate cell with contents of the snapshot */
  }
}];

self.tableView.dataSource = self.dataSource;

let ref = Firebase(url: "https://<YOUR-FIREBASE-APP>.firebaseio-demo.com")

self.dataSource = FirebaseTableViewDataSource(ref: ref,
                                       modelClass: FDataSnapshot.self,
                                        cellClass: UITableViewCell.self,
                              cellReuseIdentifier: "",
                                             view: self.tableView)

self.dataSource.populateCellWithBlock { (cell: UITableViewCell, obj: NSObject) -> Void in
    let snap = obj as! FDataSnapshot // Force cast to an FDataSnapshot
    /* Populate cell with contents of the snapshot */
}

self.tableView.dataSource = self.dataSource

FirebaseUI can also be used to back a UICollectionView using the FirebaseCollectionViewDataSource.

If you want more examples, check out the iOS README, or see our iOS chat app example. The Appledoc is available here.

Next up, Login

We're working on making mobile development as effortless as possible, so we're always looking for ways to improve development speed and reduce complexity. One major area that we hear a lot of developers struggle is around mobile authentication, which typically requires installation of third party SDKs and understanding lots of additional docs.

While we have login demo apps on Android and iOS that explain these processes, FirebaseUI 0.3 will incorporate a set of login helper classes and standard views to make adding authentication to your mobile apps simple.

Our long term strategy involves adding support for pagination, infinite scroll, and client side filtering. We'd also love to hear feature requests from you.

Submit a Pull Request!

Do you want to see those features added faster? Are you excited about making Firebase apps easier to develop? Is writing quality code your passion?

We'd love to have your help building and maintaining these libraries. Please submit issues for bugs and feature requests on Android and iOS, and pull requests are always welcome.

Lastly, if you've built anything, don't be shy! Share your apps with us on Twitter @Firebase or in our Google Group--we're excited to see what you build.

Firebase is growing faster every day, and since joining Google last year, we've gained access to world-class infrastructure and scale. Today, we're announcing across-the-board price drops to lower the barrier to entry for Firebase, so developers everywhere can create extraordinary experiences for their users.

Here are the changes we've made:

Removing Concurrent Caps

We've heard from you that concurrents are confusing. So today, we're eliminating the need to worry about them… they're now unlimited for our Candle plan and above!

To prevent abuse, we're limiting simultaneous connections to a single Firebase to 10,000 by default, which is generally enough for applications with at least 100,000 daily active users. We can scale far beyond that limit, and users can contact us to permanently raise the cap with 24 hours notice.

Doubling the Free Tier and $5 Custom Domains

Firebase is about giving people the tools to build extraordinary apps. Experimentation is core to what we stand for, and we believe people should be able to build non-trivial apps on Firebase for free.

Therefore, we are widening our free tier to:

• 100 concurrent users (2x the previous 50)
• 10 GB database bandwidth (2x the previous 5 GB)
• 1 GB database storage (10x the previous 100 MB)

In addition, you can now add a custom domain to your free app for only $5/month, with our new Spark plan. No more need to upgrade to the Candle plan just to get a custom domain!

Increasing Paid Plan Resources up to 300%

Finally, we're increasing the resource limits on all our paid plans. The Candle, Bonfire, Blaze, and Inferno plans are all seeing big increases in database bandwidth and storage, up to 3x. We've also lowered overage fees to increase flexibility as your app scales.

Here's a full summary of the changes, and you can check out our new pricing page here:

It has been a pleasure building Firebase, and it's humbling to see the great things you build with us. We've got some great new features coming soon, and are more excited than ever for the future.

Happy Coding!
