Send data via Http to a server and show response in a Webview

I have an Odoo server that is a WebApp with a website functionality.
I need to implement an Android/iOS app that comunicate with this website functionality.
The website functionality is simple:
Take the intervention code.
check if the state of the intervention sheet is visible into website.
if yes, edit the intervention sheet, if no show error message.
So I want to take the intervention number from Android (for example) and send it by HTTP request and if I get a yes response continue the editing and other stuff in a Webview....if I get "error" show the error into Android Activity.
This is my controller on server that check Code:
#http.route(['/checkCodeAction'],
type='http',
auth="public",
methods=['POST', 'GET'],
csrf=True,
website=True)
def worksheet_code_details(self, **post):
worksheet = request.env['project.task.worksheet']\
.sudo()\
.search([('intervention_number',
'=',
post.get('intervention_number'))])
if worksheet and worksheet.state_id.is_visible_on_frontend:
return redirect(f'/worksheetReadValues/{worksheet.id}')
return request.render(
"website_project_task_worksheet.worksheet_code",
{'error_code': True}
)
The request.render load an xml template of Odoo.... I can intercept this call into a webview?
Or I need to implements another controller for Android that receive for example two response (error, url_with_worksheetid)... so if I get error I show a message, if a get an URL I call the webview with this URL.

I think it's better to return the error using an HTTP Error Status Code and you would be able to better catch that error status code in your Android or IOS controller.
In Odoo you could return a raw werkzeug response like this (the following example from an existing Android-IOS-Odoo integration done by me):
return werkzeug.wrappers.Response(body, status=403, headers=[
('Content-Type', 'application/json'), ('Content-Length', len(body))
])
or you could add an status argument to your already returned render call that it's already a lazy render response wrapper, like:
return request.render(
"website_project_task_worksheet.worksheet_code",
{'error_code': True}, status=403
)

Cordova - How to change page from android code?

My question looks stupid at first glance and all my searches pointed out window.location and other JS stuff or the externalWebPage plugin. That's not what I'm looking for.
From the JAVA code, when I catch one specific exception during execution of a custom plugin, I want to force the page to move to "logout.html". I don't want to execute callback.error() or to deal with the error inside code in my webpage in any ways. I only want my transaction to be cancel and a web resource to be loaded in the current web UI.
Is there any way to do that?
Thanks in advance.

The CordovaWebView offers a showWebPage function to load any url from the native code.
From the plugin you should be able to do
this.webView.showWebPage("logout.html", false, true, null);
Also offers loadUrl
this.webView.loadUrl("file:///android_asset/www/logout.html");
And you can also use loadUrl to execute javascript so you can run the window.location from there without a callback.
this.webView.loadUrl("javascript:window.location.href='logout.html'");

You will either need to add it to your main.js interface so that you can callup page changed () and handle it in your angular code.
This can be a simple onPageNeedsChanged Handler call where you retain the context on page change context and just call it whenever you need.
Or you can call the onError callback from the caller, if it is a consistent error callback context to move you there, but sounds like you don't want to do this route.
So the easiest answer then is to just launch your own Activity with a preloaded web url and a web view. You already have access to the activity, so just make your own native activity with a full web view in it, hard coded url and then launch your activity on error.
i.e. I do it for sending an email, but it could be your own activity
cordova.getActivity().startActivity(Intent.createChooser(emailIntent, "Send mail..."));
You may even be able to get a reference to the Cordova web view, but not positive on that, but I assume you could through the tree of objects.
Does that work for you needs?
If not can you elaborate on your hesitation to handle in the onerror callback. It's fairly straight forward. Maybe I can help you there as an alternative? Retaining the callingContext and just using callingContext.error(withkey or instructions or object) is not too bad.
A35ble.writeValueToPodCharacteristic(this.device.macAddress, true, this.bytesToSend,
function (response) {
console.log("Success: " + response);
callbackContext.device.notificationReceivedFromPod(callbackContext.device.arrayBufferToString(response));
},
function (response) {
console.log("ERROR: " + response);
alert("Error Sending NSM Message: " + response);
}
);
For example I made a cordova plugin called A35ble that manages my bluetooth stuff and in this response I just show alert.

How to create async call with jquery with android using phonegap?

I have seen background service in phonegap and integrated successfully but, I need to make an ajax call to get the data from server.This call need to be happen in background process without disturbing the UI. I am unable to do this using this plugin.
And my code look like,
$.ajax({
type: "POST",
url: "http://example.com/xxx",
dataType: "xml",
async:true,
success: function (data) {
var serializer = new XMLSerializer();
var xmlString = serializer.serializeToString(data);
var finalxml= xmlString.replace(/</g, '<').replace(/>/g, '>').replace('<br/>','\n');
window.localStorage.setItem("xml_Questions",finalxml);
}
});
This ajax call has to be done with async(background) call while user doing something..
But user is not able to do anything until get the response.So I have followed Background service plugin for phonegap, but I am not able to implement this method with that plugin.
Can we do this?
Can anybody help me?
Thank you in adv...

Your $.ajax code looks right to me, so it shouldn't block the app behavior.
I don't completely understand your question... user shoudn't be allowed to do anything until the localstorage.setitem is set? If this is right, you could use jquery to enable some kind of "NEXT" button after the setItem instruction, so the user won't be able to move on until the async call is done.

Simple Phonegap application to call simple web service

I am a beginner in Phonegap and I made a simple web service in Microsoft Visual studio 2010 with two simple method. I want to call a method from that service from my Phonegap application for android platform. I am using xui library which method xhr is pretty much incomprehensible for me. I have read a lot of posts in that topic but I could not figure out how to do that.
My link to the web service looks like this: http://localhost/testservice/Service1.asmx.
This is my web service code:
[System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
public int Calculate(int firsNumber, int secundNumber)
{
return firsNumber + secundNumber;
}
}
This is my method which should test that service:
function checkWebService() {
var url = new "http://localhost/testservice/Service1.asmx?op=HelloWorld";
x$('#test').xhr(url, {error: function(){alert("failed "+this.responseText)},
callback: function(){
alert("Success " + this.responseText);
}
});
I call this method on button click and I am always getting alert with the text "Success", without "response text".
Probably my url is wrong, but I do not know which url I suppose to type.
This is for "HelloWorld" method without parameters, and I also do not know how to call method with parameters.
Any help or explanation please.

Looking at the docs (I'm not familiar with XUI), xhr is for getting a standard web page/JSON web service, where as you are calling a standard web service which will return an XML soap response (they are XML tags not HTML). You would need to parse this response to get just the result you require.
An easy way forward would be to change your web service to return a JSON response, then use eval() in javascript to give you a "typed" view of the object. XUI Example here.
If you're new to this you might find that JQuery has a larger document/community support than XUI.
BTW "Localhost" is a loopback address that essentially means "this" computer, so even it did work it would be trying to connect to the webservice on the mobile device (or emulator) rather than your server which you would typically connect to via a URL.

Rails web service not returning required response

I am newbie to rails and currently trying to build a REST api on Rails.I am trying to connect to the rest web service from my android app.
This is the controller code that i am routing the request to.
class SessionsController < ApplicationController
def create
user = User.authenticate(params[:userid],
params[:password])
if user.nil?
message="Invalid Username/Password"
return message
else
sessionId=make_sessionId
return sessionId
end
end
def destroy
end
end
I am trying to hit the create action in the SessionController.The problem is that the response i get is the html of the view whereas what i am looking forward to is the 'message or the 'sessionId' from the controller.I deleted the view files after which i am getting the html with exceptions inside it.
Can someone let me know what i should here to get the response from the controller rather than returning the html inside the view at the client.?

If you have no render in your Controller, then rails will use the view related to the action name. Try "render :text => message" for example. I hope I understood your question correctly.
