This document provides an overview of developing a mobile application with Firebase. It discusses that developing a mobile app requires functionality like authentication, databases, storage, analytics etc. It then summarizes the key services Firebase provides for mobile development including authentication, realtime database, storage, hosting, cloud messaging, remote config, testing services, crash reporting, dynamic links, invites, monetization services and analytics. The document demonstrates how to integrate and use these Firebase services in a mobile app with code snippets. It positions Firebase as providing an easy way to add functionality to an app without needing to hire backend engineers.

- 16. With Firebase • Compact team: You don’t need to hire Backend engineers • Fast iteration • Scalable • Your team can sleep at night !
- 18. Here comes the new
- 19. DEVELOP GROW EARN Backend Services Realtime Database Authentication Hosting Storage Cloud Messaging Remote Config App Quality Services Test Lab for Android Crash Reporting Acquisition Dynamic Links Invites AdWords Re-Engagement Notifications App Indexing In-app Ads AdMob Analytics
- 23. Easy to read documentation
- 25. Firebase • Strongly Integrated with Android Studio 2.2 • You can integrate Firebase with your app with just few clicks ! • [Live Demo]
- 26. Authentication • Register / Login with • Email + Password • Google • Facebook • Twitter • GitHub • Email address verification • Password reset
- 27. Authentication private FirebaseAuth mAuth; //... mAuth = FirebaseAuth.getInstance();
- 28. Creating User mAuth.createUserWithEmailAndPassword(email, password) .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful()); if (!task.isSuccessful()) { Toast.makeText(EmailPasswordActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show(); } // ... } });
- 29. Logging In mAuth.signInWithEmailAndPassword(email, password) .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { Log.d(TAG, “signInWithEmail:onComplete:" + task.isSuccessful()); if (!task.isSuccessful()) { Toast.makeText(EmailPasswordActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show(); } // ... } });
- 32. Facebook Login privatevoidhandleFacebookAccessToken(AccessTokentoken){ Log.d(TAG, "handleFacebookAccessToken:"+ token); AuthCredentialcredential= FacebookAuthProvider.getCredential(token.getToken()); mAuth.signInWithCredential(credential) .addOnCompleteListener(this,new OnCompleteListener<AuthResult>(){ @Override publicvoidonComplete(@NonNullTask<AuthResult>task) { Log.d(TAG, "signInWithCredential:onComplete:"+ task.isSuccessful()); // If signin fails, displayamessageto the user.If signin succeeds // theauthstatelistenerwill benotifiedandlogic tohandlethe // signedin usercan be handledin the listener. if (!task.isSuccessful()){ Log.w(TAG, "signInWithCredential",task.getException()); Toast.makeText(FacebookLoginActivity.this,"Authenticationfailed.", Toast.LENGTH_SHORT).show(); } // ... } }); }
- 33. Realtime Database • Cloud-hosted NoSQL database • Synchronization & conflict resolution • Access directly from your app
- 35. Realtime Database //Write a message to the database FirebaseDatabase database = FirebaseDatabase.getInstance(); DatabaseReference myRef= database.getReference("message"); myRef.setValue("Hello, World!");
- 36. Realtime Database //Readfromthedatabase myRef.addValueEventListener(newValueEventListener(){ @Override publicvoidonDataChange(DataSnapshotdataSnapshot){ //Thismethodiscalledonce withtheinitialvalueand again //wheneverdataatthislocationisupdated. Stringvalue= dataSnapshot.getValue(String.class); Log.d(TAG,"Valueis:" + value); } @Override publicvoidonCancelled(DatabaseErrorerror){ //Failedtoreadvalue Log.w(TAG,"Failedtoreadvalue.",error.toException()); } });
- 37. Storage • Easy file storage • Handles poor connectivity • Backed by & accessible from Google Cloud Storage
- 39. Uploading a file Urifile= Uri.fromFile(newFile("path/to/images/rivers.jpg")); StorageReferenceriversRef= storageRef.child("images/"+file.getLastPathSegment()); uploadTask= riversRef.putFile(file); //Registerobserverstolistenforwhenthedownloadisdoneorifitfails uploadTask.addOnFailureListener(newOnFailureListener(){ @Override publicvoidonFailure(@NonNullException exception){ //Handleunsuccessfuluploads } }).addOnSuccessListener(newOnSuccessListener<UploadTask.TaskSnapshot>(){ @Override publicvoidonSuccess(UploadTask.TaskSnapshottaskSnapshot){ //taskSnapshot.getMetadata()containsfilemetadatasuch assize, //content-type,anddownloadURL. UridownloadUrl= taskSnapshot.getDownloadUrl(); } });
- 40. Downloading a file islandRef= storageRef.child("images/island.jpg"); File localFile= File.createTempFile("images","jpg"); islandRef.getFile(localFile) .addOnSuccessListener(newOnSuccessListener<FileDownloadTask.TaskSnapshot>(){ @Override publicvoidonSuccess(FileDownloadTask.TaskSnapshottaskSnapshot){ //Localtempfile hasbeencreated } }).addOnFailureListener(newOnFailureListener(){ @Override publicvoidonFailure(@NonNullException exception){ //Handleanyerrors } });
- 41. Hosting • Serve static assets • SSL by default
- 42. Hosting Install the Firebase CLI npminstall –g firebase-tools Initialize your app $firebaseinit Add a file Deploy your website $firebasedeploy
- 43. Hosting Install the Firebase CLI npminstall –g firebase-tools Initialize your app $firebaseinit Add a file Deploy your website $firebasedeploy
- 44. Remote Config • Dynamically configures your app on-the-fly • [Live Demo]
- 45. Remote Config mFirebaseRemoteConfig=FirebaseRemoteConfig.getInstance(); Set default parameter value as a XML file in res/xml Fetch new configurations with fetch() and replace the current one
- 47. Cloud Messaging • Firebase Cloud Messaging (FCM) • Enable Push Notifications in just few LoCs • Build on top of GCM, switch to FCM ! • See in details in the next session

- 50. Crash Reporting • See crashes & impact • Version & OS drill-down • Integrated with Analytics
- 51. Crash Reporting FirebaseCrash.report(new Exception("My first Android non-fatal error")); FirebaseCrash.log("Activity created"); Basically just add dependency compile 'com.google.firebase:firebase-crash:9.0.2'
- 53. Test Lab • Test on the most popular devices before you ship • Reports & screenshots • Robo & custom tests

- 59. Dynamic Links • Customize different user experiences via a single URL • Works across platforms • Preserves URL state, even through app install flow • Analytics insights
- 62. Invites • Drop-in widget for app sharing • Supports SMS and Email • Recipient suggestions from Google • Built on Dynamic Links
- 63. Invites
- 64. Invites private voidonInviteClicked() { Intent intent =new AppInviteInvitation .IntentBuilder(getString(R.string.invitation_title)) .setMessage(getString(R.string.invitation_message)) .setDeepLink(Uri.parse(getString(R.string.invitation_deep_link))) .setCustomImage(Uri.parse(getString(R.string.invitation_custom_image))) .setCallToActionText(getString(R.string.invitation_cta)) .build(); startActivityForResult(intent, REQUEST_INVITE); }
- 65. Invites @Override protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){ super.onActivityResult(requestCode,resultCode,data); Log.d(TAG,"onActivityResult:requestCode="+requestCode+ ",resultCode="+resultCode); if(requestCode== REQUEST_INVITE){ if(resultCode==RESULT_OK){ //GettheinvitationIDsofallsentmessages String[]ids= AppInviteInvitation.getInvitationIds(resultCode,data); for(Stringid :ids){ Log.d(TAG, "onActivityResult:sentinvitation" + id); } }else { //Sendingfailedoritwascanceled, showfailuremessagetotheuser //... } } }
