RxFirebase

RxJava wrapper on Google's Firebase for Android library.

Usage

Library provides set of static methods of classes:

• RxFirebaseAuth
• RxFirebaseUser
• RxFirebaseDatabase
• RxFirebaseStorage

Authentication:

Sign in anonymously and get token:

RxFirebaseAuth.signInAnonymously(FirebaseAuth.getInstance())
                .flatMap(x -> RxFirebaseUser.getToken(FirebaseAuth.getInstance().getCurrentUser(), false))
                .subscribe(token -> {
                    Log.i("RxFirebaseSample", "user token: " + token.getToken());
                }, throwable -> {
                    Log.e("RxFirebaseSample", throwable.toString());
                });

Database:

You can query single value like:

RxFirebaseDatabase.observeSingleValue(reference.child("users").child("nick"), User.class)
            .subscribe(user -> {
                userTextView.setText(user.toString());
            }, throwable -> {
                Log.e("RxFirebaseSample", throwable.toString());
            });

or the list of values:

RxFirebaseDatabase.observeValuesList(reference.child("posts"), BlogPost.class)
            .subscribe(blogPosts -> {
                postsTextView.setText(blogPosts.toString());
            }, throwable -> {
                Log.e("RxFirebaseSample", throwable.toString());
            });

Storage

Download file from Firebase storage

StorageReference storageRef = FirebaseStorage.getInstance().getReferenceFromUrl("gs://project-1125675579821020265.appspot.com");
RxFirebaseStorage.getFile(storageRef.child("README.md"), targetFile)
        .subscribe(snapshot -> {
            Log.i("RxFirebaseSample", "transferred: " + snapshot.getBytesTransferred() + " bytes");
        }, throwable -> {
            Log.e("RxFirebaseSample", throwable.toString());
        });

or download file as bytes array

RxFirebaseStorage.getBytes(storageRef.child("README.md"), 1024 * 100)
                .subscribe(bytes -> {
                    Log.i("RxFirebaseSample", "downloaded: " + new String(bytes));
                }, throwable -> {
                    Log.e("RxFirebaseSample", throwable.toString());
                });
