SQLite / Core Data Persistence in Mobile

Persistence in Mobile Android iOS SQLite android.database.sqlite  Tables and relations Core Data  Objects  DataModel Content Providers /data/data/<Application-Package> /databases/<database-name> Only acces with root DataModel editor in Xcode for register objects and their relationships

Persistence in Mobile Objects vs Tables Object Relational Mapping

Persistence in Mobile public class Event extends Entity { public int id; public String name; } Event e = Entity.query(Event.class).where("id=1") .execute(); p.name = “Techfest"; p.save();

Cloud Computing BaaS(Backend as a Service) /MBaaS SaaS(Software as a Service)

BaaS

BaaS MBaaS= Cloud-Mobile Services + Mobile SDKs + Management Console

MBaaS APIs

MBaaS architecture

MBaaS features  API REST for CRUD operations(GET,POST,UPDATE,DELETE,PATCH)  Multi platform SDK  Cloud Storage  Push notifications  User management  Data Browser  Query language  Import/Export data  Analytics / Monetization

MBaaS features Reduce server side coding developers can focus on front-end development often providers offer SDKs that wrap REST API calls and handle in/out parameters: both HTML/JS and native (iOS, Android,Windows Phone) No server setup, ready to use (HOSTED SERVICE) Deployed on the cloud, with built-in scalability

Push Notifications Var channel= _application.pubSub.Subscribe(“channel name”); channel.Send({message}); Push Notification Service MBaaS

Push Notifications  Multiplatforms messages  Enable server applications to send information to mobile apps even when the app isn’t in use  The device displays the information using a “badge,” alert, or pop up message. A push notification uses the service provided by the device’s operating system:  iOS - Apple Push Notification service (APNS)  Android - Google Cloud Messaging (GCM)

Parse CROSS-PLATFORM SUPPORT

Connect your app with services APPLICATION ID CLIENT KEY + Parse.initialize(“APP_ID”,”C_KEY”);

Parse Application Keys + Installations

Parse Objects Parse stores data internally as flat JSON Documents, called ParseObject, with have the restriction that keys must be alphanumeric strings. Parse automatically creates ‘classes’ for ParseObjects, grouping objects with similar properties. Classes and all objects associated to them belong to applications, which can be defined on the Parse web interface. ParseObject event = new ParseObject(“Event"); event.put(“eventName", “techfest”); event.put(“eventURL", “http://techfest.uc3m.es"); event.put(“eventDate", new Date());

Parse Data browser + filter

Parse Data browser

Parse Cloud Code  Write our owns API functions with javascript

Parse with ANDROID <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> // Enable Local Datastore. Parse.enableLocalDatastore(this); Parse.initialize(this, “APPLICATION_ID", “CLIENT_KEY"); ParseObject event = new ParseObject(“Event"); event.put(“eventName", “techfest”); event.put(“eventURL", “http://techfest.uc3m.es"); event.put(“eventDate", new Date()); event.saveEventually(); //Object saved when user has network connection event.saveInBackground();

Parse Object import com.parse.ParseClassName; import com.parse.ParseObject; @ParseClassName(“Event") public class Event extends ParseObject{ public Event(){} public String getName(){ return getString(“eventName"); } public void setName(String name){ put(“eventName", name); } }} ParseObject.registerSubclass(Event.class);

Parse Object with files byte[] data = myPhotoObject.toByteArray(); ParseFile eventPhoto = new ParseFile("t3chfest.jpg", data); eventPhoto.saveInBackground(); ParseObject event = new ParseObject("Event"); event.put("name", "t3chFest"); event.put(”photo”, eventPhoto); event.saveInBackground();

Parse Object with files

Parse Data Entity type

Query Language ParseQuery<ParseObject> query = ParseQuery.getQuery(“Event"); query.whereEqualTo(“eventName", “techfest"); query.findInBackground(new FindCallback<ParseObject>() { public void done(List<ParseObject> eventList, ParseException e) { if (e == null) { Log.d(“events", "Retrieved " + eventList.size() + " events"); } else { Log.d(“events", "Error: " + e.getMessage()); } } }); query.setCachePolicy(CachePolicy.CACHE_THEN_NETWORK);

CACHE  query.cachePolicy property  CachePolicy.CACHE_ELSE_NETWORK The query first tries to load from the cache, but if that fails, it loads results from the network.If neither cache nor network succeed, there is a PFError.  CachePolicy.CACHE_THEN_NETWORK The query first loads from the cache, then loads from the network. In this case, the callback will actually be called twice - first with the cached results, then with the network results. Since it returns two results at different times, this cache policy cannot be used synchronously with findObjects.

JavaScript var event= Parse.Object.extend ("Event"); var query = new Parse.Query (event); query.find ({ success: function (results) { $scope.data.events = results; }, error: function (error) { alert ("Error:" + error.code + "" + error.message); } });

Parse Push Notifications Enabling Push Notifications

Parse SDK

Parse Push Notifications

Parse Push Notifications //Enable to receive push PushService.setDefaultPushCallback(this, RespondToPushActivity.class); ParseInstallation pi = ParseInstallation.getCurrentInstallation(); //Register a channel to test push channels Context ctx = this.getApplicationContext(); PushService.subscribe(ctx, "ch1", RespondToPushActivity.class); pi.saveEventually();

API REST

API REST AJAX CALL var headers = {"X-Parse-Application-Id":"YOUR-APP-ID-HERE", "X-Parse-REST-API-Key":"YOUR- REST-API-KEY-HERE"}; function getData() { $.ajax({ "type":"GET", "url":"https://api.parse.com/1/classes/Event", "dataType":"json", "contentType":"application/json", "headers":headers, success:function(data, status, xhr) { var result = ""; for(var i = 0; i < data.results.length; i++) { result = result +""+ data.results[i].eventName+" / "+ data.results[i].eventURL+""; }} }); }
