Android :: More Reliable Than AJAX For Phone / Server Communication?

Dec 21, 2009

I have an application that needs to send messages, repeatedly to the server. I'm currently using AJAX from the phone's browser and it works fairly reliably, but, as with all things cell-phone, not 100%. I'm curious if using Android and opening a socket to the server would give me any additional reliability, or if it would suffer from the same communication troubles that hinder the AJAX transmission.

Android :: Communication Between Java Client / Php Server App?

Feb 13, 2010

I have a simple Java client application (Android app). I have to write a PHP server application which receives a request from the Java client application to write some data to a MySQL database or read some data from the MySQL database. It should respond with a status message (Write failed/success) or the data requested respectively. How would I get the Java client send a request and receive the reply from the PHP program and how would the PHP program receive the request and send the reply? I have googled about SOAP and REST architectures, but looking for a simple tutorial which will allow me to implement this simple program.

Android :: Options For Client Server Communication

Nov 6, 2009

I'm currently in the research phase of my dissertation project.My project is a ticket booking system for a mobile device and I have chosen to target Android.I anticipate the need for a client/server architecture with a central server, and so am currently looking at how Android could communicate with such a server. The server would grant the client access to ticketing information, and the client would send information about ticket bookings to the server. I'm looking at Java EE for the server as Java is the language I'm most experienced with.I'm aware that Android comes with java.nio and java.net, as well as some org.apache packages, but am also looking for libraries/technologies that would be possible to use with Android.

Android Server Client Communication - Transmitting GPS Coordinates

Jan 21, 2013

I am trying to create a basic application that transmits GPS co ordinates of the device to a server. I am a complete noobie to socket programming.

As a stepping stone, I am following a tutorial, that creates the server, and the android client, it is designed to send an input from the user to the server and the server prints it on the console.

I'm becoming quite familar with how to set up the basics of the server and the client i.e. opening ports etc. The problem with this is, when hit send, the app crashes, when tested on the emulator, there is obviously an issue, but I can't see it.

When I test with device, and hit send, there is nothing printed to the console. I've attached both the client and server code below, the ip in the code below is for the emulator, I change this to my device ip with testing with it.

****SERVER****

[HIGH]
public class Additional_Server {
private static ServerSocket serverSocket;
private static Socket clientSocket;
private static InputStreamReader inputStreamReader;
private static BufferedReader bufferedReader;
private static String message;

[Code] ....

****CLIENT****

[HIGH]

import android.os.Bundle;
import android.app.Activity;
import java.io.IOException;
import java.io.PrintWriter;

[Code] .....

General :: Couldn't Establish Reliable Connection To Server

Jun 12, 2014

I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:

[URL]

From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.

So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not work either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I can effectively not use my phone- I can't use most apps and can't download any.

Samsung Galaxy I7500 :: Can't Establish A Reliable Data Connection To Server

I have a Samsung i7500 (Galaxy).Originally, it had Android 1.5 installed, but I could not enter the Google Market with my google account and got this message: "Can't establish a reliable data connection to the server".I read here and across the web I should Factory-reset my phone, but it did not work.So I upgraded the firmware to Android 2.1 using this guide: How to Mustymod It worked, and now the phone had Android 2.1 installed, but I still cannot access the Google Market with my Google account. This time I did a factory-reset (Settings -> Privacy -> Factory reset) and also followed this guide to delete the provider-settings (eventually I removed the whole /data/data/com.android.providers.settings/ directory and not only that file.

Android :: How AJAX Requests Work On 2.0 / 2.2 Emulators?

Jul 22, 2010

I'm testing out a web page on the Android 2.0 and 2.2 emulators, and the jQuery.ajax() requests that the app makes have slightly different behaviors regarding HTTP Authentication Headers. The server I'm making requests to requires basic authentication, and the ajax requests in 2.2 send the proper auth header. In 2.0, I am debugging with Fiddler, and it seems that the requests do not include the auth header, and the server rejects the request with a 401.2 error. I don't think it matters, but the server is running IIS 7. One interesting thing I noticed while debugging the web requests is that Android 2.2 makes two requests for each resource, whether or not it's an XHR. One does not contain the Auth header, and the second one does. In 2.0, it seems to make 2 requests for everything but XHR's:

Here is the 2.2 header for the first XHR:
GET http://192.168.1.111/sonar/mobileweb/sonar/views/week/init.ejs HTTP/1.1
Host: 192.168.1.111
Accept-Encoding: gzip
Referer: http://192.168.1.111/sonar/mobileweb/sonar/sonar.html
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

The 2.2 header for the second XHR:
GET http://192.168.1.111/sonar/mobileweb/sonar/views/week/init.ejs HTTP/1.1
Host: 192.168.1.111
Accept-Encoding: gzip
Referer: http://192.168.1.111/sonar/mobileweb/sonar/sonar.html
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Authorization: Basic cGFyaXZlZGFcZGF2aWQubW9ycmlzOjIzbkx2ZWxsbGw=
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

And the 2.0 header:
GET http://192.168.1.111/app/views/week/init.ejs HTTP/1.1
Host: 192.168.1.111
Accept-Encoding: gzip
Referer: http://192.168.1.111/app/app.html
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.0; en-us; sdk Build/ECLAIR) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

Has anyone experienced this behavior before? It is basically causing my app to not work at all in version 2.0. Version 2.1 seems to act the same as 2.0.

Android :: Intercept AJAX Call From WebView

Oct 15, 2010

I want a HTML/javascript application, running in a WebView, to make AJAX calls that are handled by the Java code. Ideal would be to just intercept the call (easy, just use shouldOverrideUrlLoading()) and 'return' some data. However, I don't find a way to 'return' a response to the WebView, other than calling a javascript function using loadUrl(). This will not work for me, as the HTML/js app is a drop-in application which I don't control. As far as the HTML/js app concerns, it just does an AJAX call and receives some data back.

Android :: Ajax Cross Domain Requests

Nov 7, 2010

The behavior of XMLHttpRequests in Android is very odd when doing cross domain requests. The browser should either fail with an error and not perform the request, or it should follow CORS (http:// www.w3.org/TR/access-control/) and start with an OPTIONS request to the remote domain. The Android browser (2.1 and 2.2) instead performs the request, which is received by the remote server (and this is the dangerous part both for data leaking and remote attacks), but the response is not set in the javascript (status of 0 and responseText null)

Android :: ASP.NET AJAX CalendarExtender Not Working Properly With Browser

Jan 16, 2010

I'm creating a webapp for Android mobile phones with ASP.NET and the Ajax Control Toolkit. I've included a CalendarExtender-Control which popups a calendar when focusing the associated Textbox-Control. If I select this textbox on my mobile phone, the Android webbrowser highlights it with an orange border. The problem is that this border is shown in front of my Calendar popup. Has anybody any idea how to fix this issue?

Android :: WebView For Form Based Local AJAX Application

Feb 18, 2009

I'm thinking of using WebView as a container for "Form" based JavaScript+DHTML applications. This is simple fill-out-forms like you have on the web, but now on mobile like for note taking, order taking, and the like.This is to allow web developers to build the bulk of the application - Javascript will perform validation, computations, etc.On the Java side, I only need to implement database CRUD operations, and a ListView to scroll over the forms.To minimize the learning curve on the JavaScript side, I've been thinking on how to emulate AJAX calls so that the web developers don't need to learn new methods to call on the JavaScript-Java bridge. Of course this isn't possible using XMLHttpRequest, so I'm thinking of adapting JQuery or other Javascript libraries for this purpose.

Android : Browser Crashes On Ajax Calls - When Viewport Meta Tag Is Defined

Apr 8, 2010

I am building a web app, which is intended to run on the Android browser. When I have a webpage that contains any kind of viewport meta tag, like this:

<meta name="viewport" content="width=400"/>

My webpage crashes on ajax calls. It happens when using the emulator, the actual browser on my nexus one, and on a droid (all running Android 2.1). Without the meta tag, the ajax calls run as they should.

I am absolutely going to use my Google Voice for texting (hey, its free). I'm considering using it as my primary number too.

My question: How reliable is Google Voice w/ texting and calls? Any reason NOT to go ahead this route?

I was always going to use it for text (I understand they are instant now), but for ease of communicating w/ my friends and family I'm also considering giving out my number for calls as well.

Android USB Communication

Dec 17, 2012

I am new to android programming and I am trying to set a connection with the android as a host. I have included the following imports:

import android.hardware.usb.UsbManager;
import android.hardware.usb.UsbInterface;
import android.hardware.usb.UsbEndpoint;
import android.hardware.usb.UsbDeviceConnection;
import android.content.Context;

My problem is when I use this code :m_usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);The eclipse editor shows a message saying that getSystemService(String) is undefined for the type CPrinterCommands(The class that I am using). Quick fix gives as a solution to create a method called getSystemService, however I can't find why I would need to create a method, all the examples I found, none of them had a method getSystemService.
