I am developing an android app which collects the configuration of that particular phone and displays it on the phone.
I want that data , i.e , configuration values of a phone, to send to my server. Can anyone help me with the code.
I am getting the codes for sending data from server to the application but not from app to the server.
You have to use websevices, either SOAP or REST. For SOAP you can use KSOAP2 KSOAP2 library or for REST use this link.
Try using Spring for Android together with Android Annotations. e.g
#Rest(rootUrl = "http://company.com/ajax/services", converters = { MappingJacksonHttpMessageConverter.class })
public interface MyRestClient {
#Get("/events")
EventList getEvents();
}

Most of the backend stuff is in PHP which handle JSON request and response flow of data from Android app to backend.
I'd like to start writing Python code to handle the extra features I'm going to add in my app. How can I do that? Do I need to install Django or something like it in the backend? Our webhost does show "Python support". I'm guessing just a couple of Python classes and some helper library files would suffice.
But here's where I'm conceptually stuck:
In Android, on the app, in the user's side, suppose I send all my queries to backend with this function:
//Pseudo code on Android app
getServerResponse()
{
url = " ??? ";
jsondata = {somedata[a:b]};
response = sendData_andGetResponse(jsondata); // suppose this function sens json data and expects a server response.
showResults(response);
//Pseudo code on backend - BackendProcessing.py
def processRequest():
# some processing done here
response = "some_processed_data"
return response
My problem is, what and how do I integrate the backend Python code and the client side Android app code to communicate with each other. What should the URL be in my Android code to pass data from user to backend? How do I link them?
Do I need to specially setup some third party Python API to handle calls from the Android app at the backend? Or can I just do it with simple Python functions and classes with HTTP request and responses coming in for a particular URI?
You can include URL of the backend server in the android code. Define a variable for the URL of your backend server and use Httppost method for communication between backend and frontend.
Details here http://developer.android.com/reference/org/apache/http/client/methods/HttpPost.html
You can do it with simple Python functions and classes with HTTP request and responses coming in for a particular URI. A third party Python API is not necessary.
You can also use Python based web frameworks like Django for the backend.
My project is in symfony where I need to get some data from android. So I implemented json encoding on both parts but my web application does not receive the data from android. I found the android is being unable to send data to symfony..
The code for android where the web link is written is as follows:
JSONObject json = jsonParser.getJSONFromUrl("http://external.apostle.digibiz.com/web/app_dev.php/api/test", params);
What is the error ??
I like to raise some questions regrading Yii framework and Android applications. I am going to build a mobile application in Android platform and implementing Yii framework as server side. I like to know how much Yii framework supports Android platform? Are Yii framework web services fully compatible with Android?
And, if can anyone suggest some tutorial or useful information, that will be very useful to me...
Check out this: Yii REST API
You can use JSON / XML to communicate your android application with the php yii framework by building a simple REST API.
In order to do use the REST API this, you need to send HTTP request (Get / Post) from Android application. Then perform your operation based upon the request and send again in JSON formate using php json_encode or XML if you preferred.
You can also perform it using google Gson. it will help you to create JSON from java object.
Refer this: Simple API using Yii
I have done similar recently,
Yii side
you need custom controller sending json array and you can refer Yii REST API
public function actionTest()
{
$commands = Command::model()->findAll();
$cmdlist = array();
if( $commands != '0'){
foreach( $commands as $item )
{
$object = array();
$object ['cmd'] = $item->command;
$object ['command'] = $item->getCommandOptions($item->command);
$object ['number'] = $item->number;
$object ['id'] = $item->id;
$cmdlist[] = $object;
}
$arr['command'] = $cmdlist;
}
header('Content-type: application/json');
echo json_encode($arr);
Yii::app()->end();
}
android side
You need a neat Async Http client with Json parser. I used android-async-http
I have an Android application that is on the market that I am switching to using the Yii framework. I use the http://www.yiiframework.com/extension/restfullyii/ extension. So far it's been great. I had a couple of issues with security and other things but overall the tool is what you will need. All you really care about for yii is having a restful API the rest of the logic should really be handled in your Android application. Also as a response type at this point I would only use json. I tried to implement a Android XML framework and decided to pull back because json did everything I needed to and was easy.
I don't know anything about Ruby, but I think what I'm trying to do is pretty simple. I have an app that needs to send a url query like this to a heroku database: http://dartmouth.heroku.com/dnd/search.json?query=sebastian, then receive the data that comes back and organize it for the user. How do I send and recieve a query like this?
EDIT: I downloaded Spring and added the rest template jar to my projects build path. I tried using this code:
String url = "http://dartmouth.heroku.com/dnd/" + dataBase + "json?query=" + searchContent;
RestTemplate rstTemplate = new RestTemplate();
PersonList pList = rstTemplate.getForObject(url, PersonList.class);
but "RestTemplate" is not recognized. Did I miss an installation step?
You need to start by making an HTTP request for the data and then parsing the results. I would suggest trying out the Spring Android library to accomplish this: http://www.springsource.org/spring-android
Check out the explanation here: http://mike.bailey.net.au/2011/02/json-with-ruby-and-rails/
You can use a plugin called HttpParty for sending the request. Ruby on rails will interpret the json response by using the json library. The example on the above mentioned page might make things clearer.
I am wondering what is required to setup a server so that you can store data on it, and then have an application send requests to it to store and receive data. More specifically, I am working on an Android application where a user will generate data and then that should be stored on a server so other users can access it. But I do not know how setting up a server to be capable of this works. I have worked on Android applications in the past that sends requests (put, post, get, etc) to a server, but that back end was already set up for me. Any info or resources about setting this up would be great.
There are many, many different ways to accomplish this.
Since you're already working with a Google technology, Android - you could start by creating a Google App Engine project. Following the tutorials you can get started setting up a simple back end solution that will store data for you and you can make requests to it for that data.
Another advantage to this for you is that you don't have to learn how to install software on a server and all the dependencies that arise from that, etc. Simply set up a new account and push-button deploy through Eclipse or command line.
And since you've used Java in Android, you can use JAva for Google App Engine (GAE) too!
Getting started: http://code.google.com/appengine/docs/java/gettingstarted/introduction.html
You can try ready to use BAAS/PAAS services to store your data, e.g. QuickBlox for Android http://quickblox.com/developers/Android, where you can manipulate with your data with few strings
QBLocation location = new QBLocation();
location.setLatitude(35.0);
location.setLongitude(53.0);
location.setStatus("I'm at this place");
String someImportantString = "Dr. Henry Walton Indiana Jones";
QBLocations.createLocation(location, new QBCallbackImpl() {
#Override
public void onComplete(Result result, Object context) {
// retrieve context object inside callback
String passedContextObject = (String) context;
System.out.println(passedContextObject);
// do stuff with result
}
}, someImportantString);
All logic of data exchange with server is encapsulated in framework.
