Whats new in Liferay Mobile SDK 2.0 for Android

Liferay Mobile SDK has been enabling developers to create native apps backed by Liferay Portal’s power. We’ve been using it in production since 2013 and have noticed many improvement points. We also listened to the community and added new features that will make app development even faster. The new Liferay Mobile SDK for Android brings a lot of new features that boosts apps development. Things from automatic JSON parsing and RxJava compatibility to better code generation are ones of the improvements in this new major release.

1. What’s New in Liferay Mobile SDK 2.0 for Android Silvio Santos, Mobile Lead Engineer DEVCON | MODCONF 2016
10. http://localhost:8080/api/jsonws
11. BUILD REQUEST JSONObject command = new JSONObject();
 String method = "/dlapp/add-folder";
 JSONObject params = new JSONObject();
 
 params.put("repositoryId", repositoryId);
 params.put("parentFolderId", parentFolderId);
 params.put("name", name);
 params.put("description", description);
 
 command.put(method, params);
12. DefaultHttpClient client = new DefaultHttpClient();
 
 AuthScope authScope = new AuthScope(
 AuthScope.ANY_HOST, AuthScope.ANY_PORT);
 
 Credentials credentials = new UsernamePasswordCredentials(
 username, password);
 
 client.getCredentialsProvider().setCredentials(
 authScope, credentials); CONFIGURE HTTP CLIENT
13. EXECUTE REQUEST HttpPost post = new HttpPost(url);
 post.setEntity(new StringEntity(command.toString()));
 
 HttpResponse httpResponse = client.execute(post);
 
 HttpEntity entity = httpResponse.getEntity();
 String response = EntityUtils.toString(entity); …handle exceptions

19. 1. @NNOTATION BASED API 2. DEFAULT PARAMETERS 3. POJO AUTO PARSING 4. REQUEST CANCELATION 5. BETTER CONFIGURATION API 6. RxJAVA INTEGRATION
20. @NNOTATION BASED API
21. CREATING API 
 public interface GroupService {
 
 
 Call<JsonArray> getUserSites();
 
 }

 public interface GroupService {
 
 
 Call<JsonArray> getUserSites();
 
 }
23. CREATING API @Path("/group")

 JsonArray sites = call.execute();
28. ASYNC INVOKE METHOD call.async(new Callback<JsonArray>() {
 public void onFailure(Exception exception) {

 public void onSuccess(JsonArray result) {
 } });
29. ASYNC INVOKE METHOD call.async(new Callback<JsonArray>() {

 //new data event, do something
 },
 throwable -> {
 //on error
 });

 .subscribe(sites -> {
 },
 throwable -> {
 });
67. RxJAVA INTEGRATION

 .subscribeOn(Schedulers.io())
 .observeOn(AndroidSchedulers.mainThread())
 .subscribe(sites -> {
 },
 throwable -> {
 });
68. RxJAVA OPERATORS map filter concat zip cache debounce
69. MAP map(x -> x + 1) 1 3 2 2 4 3
70. FILTER filter(x -> x > 1) 1 3 2 3 2
71. CONCAT concat 1 3 2 5 4 3 2 1 4 5
72. RxJAVA INTEGRATION 
 Observable.concat(dbSitesObservable, getUserSites())
 .first()
 .subscribeOn(Schedulers.io())

74. RxJAVA INTEGRATION 
 Observable.concat(dbSitesObservable, getUserSites())
 .first()
 .subscribeOn(Schedulers.io())
 .observeOn(AndroidSchedulers.mainThread())
 .subscribe(sites -> {
