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

7. 2012

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
