Call a method from web app to android app - android

Is it possible to call a method / API / web service from a web application to an android application, something like android app become web service provider and the web app become web service client,
I would like to refresh data on an android app by clicking on a button on a web application,

Something like Google Cloud Messaging - http://developer.android.com/google/gcm/index.html
would probably be your best choice.

You can use I-Jetty in your app and make your app as the web server.. use the source code and run the server from a android service. More detail can be found at following link:

how to secure android and angularJS using REST API services spring boot backend

I have a project, angularjs webapp (backend java and spring boot) and uses google map too, there is an android app that sends alerts to this webapp and those show location on the webapp’s map. However when I implement spring security it would secure the webapp and REST api, but will prevent the alerts from android showing on the map (can not find resource)….
I want an easy simple way to secure the app without stopping the REST API services, yes I want to secure my API but still want to be able to show the alerts sent from android device, also still accepts new registration from android users....(android users cant access webapp they only register to use android app and will be added to database..they will need to be able to post their info...)
I tried oauth2 using google sing in, but I must be missing something as it wont load,..If you think this is the right approach please confirm...I will further look into it...Or direct me to tutorial or give me any suggestions...
P.S I am using bluemix platform as a service at the moment and CLearDB database service from bluemix
I am a student and all this is new to me...Thanks

Android app web service hacking

I have a one android application in store.I read and write to my data from web service (JSON).Hackers can download to apk and hack this app and see my web services address ?
Yes, they can if your Web Service is not secured enough. They will not even need to reverse-engineer your app, they could just see to what IP their phone connects when they open the app. So they can get these informations:
Where your Web Service endpoint is
What data you are sending to the web service
What data the service sends back
They could also reverse-enigneer (decompile) your App and see the source code and the logic behind it.
This should not be enough to get into your server. How do they sign on to the Web API? Is there any authentication service?
I use SSL.https
E.g :
www.domain.com?webservices.php?MethodName=ListStudents&className=12A&username=webserviceuser&password=webservicepassword&returntype=JSON
this web service return to JSON data.

Integrate Appcelerator Cloud Services to a custom website made with ASP.NET

I'm really new to mobile world, so I'd like to get some opinion from experienced people.
After several days searching over the internet, I'm wondering if it's possible
integrate Appcelerator Cloud Services to a custom website made with ASP.NET, for example.
Although my mobile application, built with Titanium, it's linked to ACS, and works fine, I don't know if
it's possible to manage data stored in ACS from a custom website. To clarify, in one point there is my mobile application
talks to a webserver (ACS, for example) and other point there is a website, to manage the data stored in ACS.
What do you think, someone achieved this?
Or is it preferable to write a webserver from the scratch, store my data in somewhere, and forget about ACS?
Thank you.
Appcelerator says
Appcelerator Cloud Services (ACS) is a Mobile Backend as a Service
(MBaaS), offering a fast and easy way to build connected mobile apps.
Choose from a library of services such as push notification, status
updates, photo storage, and social integration, or create your own
custom cloud services.
Here in this page - Getting Started: Using the Javascript SDK - you can see how we can use javascript SDK which lets you access the Appcelerator Cloud Services server through some simple to use JavaScript calls. You can use this to develop web-based app.
ACS has a REST API which you can access through anything that supports xhr (which .NET does). For instance, to create a new user in ACS, you use the following link:
https://api.cloud.appcelerator.com/v1/users/create.json?key=YOUR APP APP KEY?email=john.smith#company.com&role=teacher
There are other properties you can tag onto the querystring to create a new user from a REST call. They have a complete API using REST. It's all documented. You can even send push notifications to devices from your custom website using the REST API! It's pretty cool.

Good luck!

Communicate with application from Web

I want to develop a website that allows me to manipulate my android phone afar, what can i use as a URL to link the 2 applications ? should i use webservices ?
You can trigger special funktions like sending an sms or starting a call by using special links
Examples for Android an iOS:
Call 123456789
Send SMS
I see no way of direct communication with the native app. The website could send the requests to a server and than use push notifications to trigger the changes in the native app.
You have 3 choices.
RESTful services(they are like stripped down Web services)
through json and php or whatever script you know
Google's Cloud Messaging
Since you seem eager to go with Web Services I suggest the first. It would be easier for you

Android application as Web Service

Is it possible implement an Android application as a web service?
On the official site I've read:
Note: If you want to develop a server-side application, we recommend
that you implement your application as
a servlet running in a servlet engine
like Tomcat or full-blown JSEE
container like Geronimo. If you prefer
to implement a server-side application
based on our HttpService, we'll assume
that you know what you're doing and
that you don't need help in figuring
out which interceptors need to be
configured.
How can I implement this? Apache TOMCAT can run on Android?
Is it possible implement an Android
application as a web service?
You can create an Android service that will open up some server socket and will listen for HTTP requests. However, Android will eventually kill off that service, either automatically after it is unused or at user request. And, nobody will be able to access the service except on the same WiFi LAN.
IMHO, truly implementing a Web service on Android is pointless.
I think they're saying that you can write a server-side application for an Android user to access, not that you'd run Tomcat on the Android device itself.
