  • Motorola Droid App Recommendations

    - by Brian Jackett
    Just as a disclaimer, the views and opinions expressed in this post are solely my own and I’m not getting paid or compensated for anything.     Ok, so I’m one of the crazy few who went out and bought a Droid the week it was released a few months back.  The Motorola Droid was a MAJOR upgrade in phone capabilities for me as my previous phone had no GPS, no web access, limited apps, etc.  I now use my Droid for so much of my life from work to personal to community based events.  Since I’ve been using my Droid for awhile, a number of friends (@toddklindt, @spmcdonough, @jfroushiii, and many more) who later got a Droid asked me which apps I recommended.  While there are a few sites on the web listing out useful Android apps, here’s my quick list (with a few updates since first put together.) Note: * denotes a highly recommended app     Android App Recommendations for Motorola Droid (Updated after 2.1 update) RemoteDroid – install a thin client on another computer and Droid becomes mouse pad / keyboard, control computer remotely PdaNet – free version allows tethering (only to HTTP, no HTTPS) without paying extra monthly charge.  A paid version allows HTTPS access. SportsTap – keep track of about a dozen sports, favorite teams, etc *Movies – setup favorite theaters, find movie times, buy tickets, etc WeatherBug elite – paid app, but gives weather alerts, 4 day forecast, etc.  Free version also exists.  (Update: Android 2.1 offers free weather app, but I still prefer WeatherBug.) *Advanced Task Killer – manually free up memory and kill apps not needed Google Voice – have to have a Google Voice account to really use, but allows visual voice mail, sending calls to specific phones, and too many other things to list AndroZip – access your phone memory like a file system Twidroid – best Twitter client I’ve found so far, but personal preference varies.  I’m using free version and suits me just fine. Skype (beta) – I only use this to send chat messages, not sure how/if phone calls works on this. (Update: Skype Mobile app just released, but uninstalled after few days as it kept launching in background and using up memory when not wanted.) *NewsRob – RSS reader syncs to Google Reader.  I use this multiple times a day, excellent app. (Update: this app does ask for your Google username and password, so security minded folks be cautioned.) ConnectBot – don’t use often myself, but allows SSH into remote computer.  Great if you have a need for remote manage server. Speed Test – same as the online website, allows finding upload/download speeds. WiFinder – store wifi preferences and find wifi spots in area. TagReader – simple Microsoft Tag Reader, works great. *Google Listen – audible podcast catcher that allows putting items into a queue, sync with Google Reader RSS, etc. I personally love this app which has now replaced the iPod I used to use in my car, but have heard mixed reviews from others. Robo Defense – (paid app) tower defense game but with RPG elements to upgrade towers over lifetime playing. I’ve never played FieldRunners but I’m told very similar in offering. Nice distraction when in airport or have some time to burn. Phit Droid 3rd Edition – drag and drop block shapes into a rectangle box, simple game to pass the time with literally 1000s of levels. Note this game has been updated dozens of times with numerous editions so unsure exactly which are still on the market. Google Sky Map – impress your friends by holding Droid up to sky and viewing constellations using Droid screen. wootCheck Lite – check up on daily offerings on Woot.com and affiliated wine, sellout, shirt, and kids sites.   Side notes: I’ve seen that Glympse and TripIt have recently come out with Android apps.  I’ve installed but haven’t gotten to use either yet, but I hear good things.  Will try out on 2 upcoming trips in May and update with impressions.         -Frog Out   Image linked from http://images.tolmol.com/images/grpimages/200910191814100_motorola-droid.gif

  • Why am i getting same values of different JSON date values?

    - by Maxood
    I do not know the reason why am i getting same values of different JSON date values. Here is my code for parsing date values in JSON date format: package com.jsondate.parsing; import java.text.SimpleDateFormat; import java.util.Date; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class JSONDateParsing extends Activity { /** Called when the activity is first created. */ String myString; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView tv = new TextView(this); //Date d = (new Date(1266029455L)); //Date d = (new Date(1266312467L)); Date d = (new Date(1266036226L)); //String s = d.getDate() + "-" + d.getMonth() + "-" + d.getYear() + d.getHours() + d.getMinutes() + d.getSeconds(); // SimpleDateFormat sdf=new SimpleDateFormat("yyyy MMM dd @ hh:mm aa"); //Toast.makeText(this, d.toString(), Toast.LENGTH_SHORT); Log.e("Value:", d.toString()); myString = d.toString(); String []words = myString.split(" "); for(int i = 0;i < words.length; i++) Log.e("Value:", words[i]); myString = words[2] + "-" + words[1] + "-" + words[5] + " " + words[3]; tv.setText(myString); setContentView(tv); } }

  • Can't authenticate mobile client with node.js (using passport.js)

    - by Pazinio
    I'm trying to build some CRUD application with node.js as a back-end API (express) and web-app (backbone) and mobile client (native android) as front-ends.(I'm node.js beginner) My server solution is based on the following great tutorial 'easy-node-authentication'. In my android app I have managed to get the user Google-Token after I completed the authentication step with Google Plus SDK.(mobile to google-plus directly request). I'm trying to understand and find right and elegant way to re-use a given google-token and authenticate again my android user through Google-Plus account to ensure the mobile client holds real token, then add a new entry (id, token, email, name) to my users table DB within my node back-end. The question is: what should be my next step in case I want to keep my back-end without changes? should I send a GET request with the token as a cookie to /auth/google? maybe to /auth/google/callback? another URL? Does this make sense at all? Please note: I'm aware to the fact the mentioned above 'easy-node-auth' solution is based on sessions and cookies. having said that, i'm still trying to understand if there is a convenient way to integrate both (android and node) as it works good for my web-app and node. Thanks in advance.

  • Finally, upgrade from Nokia X3 to Samsung Galaxy S III

    This time, something slightly different but nonetheless not less interesting, hopefully. Living on a remote island like Mauritius, ill-praised 'Cyber Island' in the Indian Ocean, has its advantages in life style and relaxed environment to life in but in terms of technological aspects it can be quite a nightmare. Well, I guess this might be different story to report about... one day. Cyber Island Mauritius Despite it's shiny advertisement as Cyber Island and business in ICT hub to Africa, Mauritius is not on the latest track of available models in computer hardware or, in the context of this article, cellulars or smart-phone, or communication technology in general. Okay, I have to admit that this statement is only partly true. Money can buy, even here in Mauritius. Luckily, there are ways and ways to deal with this outcry of modern, read: technological, civilisation issues. Online shopping you might think? Yes, for sure, until you discover in your checkout procedure that a small island in the Indian Ocean isn't a preferred destination for delivery and the precious time you spent on putting your items into your cart and feeding your personal level of anticipation gets ruined on the last stint. Ordering from abroad saves you money Anyway, I got in touch with my personal courier and luckily there were some extra-kilos left in the luggage. First obstacle sorted, we have a Transporter! Okay, on the next occasion off to Amazon online and using their Prime service for fast delivery. Actually, the order was placed on Saturday evening and everything got delivered on Tuesday morning - nice job in less than 72 hours. Okay, among the items of that shopping rush I ordered a shiny Samsung Galaxy S III 16GB in oceanic blue - did I mention, that you hardly get a blue model in Mauritius? - for my BWE. Interesting side-notes: First, Amazon Germany dropped the prices for roughly 30% on the S3, and we got the 16GB model for less than 500 Euro (or approx. Rs. 19.500,-) compared to the usual Rs. 27.000,- on the local market. It even varies whether the local price is inclusive or exclusive VAT (15%). Second, since a while she was bothering me to get an iPhone and an iPad for her, fair enough I thought, decent hardware, posh design and reliable services. Until we watched the 'magical' introduction of Samsung's new models at the IFA exhibition, she read the bashing comments on Google+ on the iPhone 5 and I gave her a brief summary on the law suit between Apple and Samsung in the USA. So, yes, Samsung USA is right, the next big thing is already here - literally. My BWE loves the look and touch of the Galaxy S3. And for me it was more cost-effective in terms of purchases done at the App Store, ups, Play Store. Transfer of contacts, text messages and media files Okay, now that the hardware is in place, how to transfer all those contacts, text messages, media files, etc. between those two devices? In the past, I used to use the Nokia Communication Suite between various models but now for Android? Well, as usual Google and Bing are reliable friends and among the first hits I came across an article about How to Transfer Contacts from Nokia to Android. Couldn't be easier, right? Well, sort of... my main Windows systems are already running on Windows 8, and this actually caused problems with the mobile/smart-phone device drivers. The article provides the download for an older version 1.10 which upgrades to 2.11 (as time of writing this entry) but both couldn't get the Galaxy S3 and the Nokia connected. Shame on me... the product page clearly doesn't mention Windows 8 (for now) and Windows 8 isn't available for the general audience at all... After I took a spare machine running on Windows Vista everything went smooth. Software installed, upgrade done, device drivers for Android automatically downloaded and installed, and the same painless routine for the Nokia part. I think, I rebooted the system twice during the whole setup procedure but hey, it was more or less a distraction while coding some stuff in ASP.NET MVC and Telerik Kendo UI. The transfer of contacts and text messages was done via Wondershare MobileGo for Android, and all media files by moving the additional microSD card from one device to the other. But even without an external SD card, it would have been very easy to copy the files via Windows Explorer directly. Little catch and excellent service Fine, we are almost done and the only step left is to shift the SIM card... Ouch, gotcha! The X3 uses a standard size SIM card while the S III only accepts microSIM form factor. What an irony, bigger smartphone needs smaller SIM card. Luckily, the next showroom of Emtel is just 5 mins away up the road, and the service staff over there know their job. Finally, after roughly 10 mins of paper work, activation and small chit-chat, the S3 came to life on the mobile network. Owning a smart-phone now and knowing that my BWE would like to interact more on social networks away from home, especially to upload pictures and provide local 'check-ins', I activated a data package for her in advance, too. Even that it is Saturday, everything was already done and ready to be used. Nice bonus: The Emtel clerk directly offered me to set up the configuration for the Emtel data services, yes sure, go ahead, this saves me to search for that in the settings. Okay, spoiler-alert here, setting a static APN to access the Emtel network and the internet wouldn't be a challenge. But hey, she already had the phone in her hands and I could keep my eyes on the children. Well done, Emtel! Resume Thanks to the useful software package by Wondershare is was a hands-free experience to transfer all the data from a Nokia mobile on Symbian S60 to a Samsung Galaxy S III on Android Ice Cream Sandwich (ICS). In the future, this wont be a serious issue at all anymore thanks to synchronisation services and cloud storage. And for now, I'm only waiting for the official upgrades for Jelly Bean.

  • How can I export PDF from InDesign so that transparency renders properly on all platforms?

    - by strangeronyourtrain
    Gradients, including drop shadows, all show up as solid blocks when I view my document on an Android phone. I tried different PDF compression and compatibility settings in an attempt to flatten and rasterize all the graphics, but it's clearly not working, as the Android viewer still identifies the outlines of transparent shapes instead of the blended pixels. Is there any way to truly flatten these PDF graphics, so that it doesn't matter whether a PDF viewer supports transparency, while keeping the text as text?

  • Where can I report an issue with IIS?

    - by Nathan Taylor
    While working with an ASP.NET application on Chrome for Android I discovered that Request.Browser.Cookies returns False for that browser (despite the browser supporting cookies). Based on what I've read, this indicates a problem with the database which ASP.NET (and, I assume, IIS) uses to look up information about different UserAgents. The fact that it returns False means that the database is either missing Chrome for Android, or has invalid data for it. What is the a proper place to report IIS issues like this?

  • Building a video wall with devices

    - by machunter
    I am entertaining building a video wall made out of many android devices. But I have to say I have no clue about how to go about it? The fact that these are android devices is not very important I am curious about the general approach to doing video walls with many separated devices. At best the desktop of one machine should be displayed on all the devices. If not I would be also interested in just showing just a video on that wall.

  • Require CoreTelephony framework examples.

    - by prathumca
    Greetings everyone. Can any one has a working example for the CoreTelephony framework? I dumped all the CoreTelephony headers using class-dump and added them to "/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/System/Library/PrivateFrameworks/CoreTelephony.framework". Now I'm following the Erica's tutorial (http://blogs.oreilly.com/iphone/2008/08/iphone-notifications.html). I added these following lines of code in my main.m, id ct = CTTelephonyCenterGetDefault(); CTTelephonyCenterAddObserver( ct, NULL, callback, NULL, NULL, CFNotificationSuspensionBehaviorHold); but I'm getting a warning like, Implicit declaration of function "CTTelephonyCenterGetDefault()" and "CTTelephonyCenterAddObserver(...)". Can any one has full working example, which will explain how to get the CoreTelepony notifications?

  • Can't get iPhone device token

    - by d.andreykiv
    Hi. I'm trying to get iPhone device token using following code - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; NSLog(@"Registering for push notifications..."); [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert]; } - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken { NSLog(@"Registered!@@"); } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"application:didFailToRegisterForRemoteNotificationsWithError: %@", error); if ([error code] != 3010) // 3010 is for the iPhone Simulator { // show some alert or otherwise handle the failure to register. } } but only getting "2010-04-02 18:23:35.434 Untitled[3133:207] Registering for push notifications..."

  • Why is the JVM stack-based and the DalvikVM register based?

    - by aioobe
    I'm curious, why did Sun decide to make the JVM stack-based and Google decide to make the DalvikVM register based? I suppose the JVM can't really assume that a certain number of registers are available on the target platform, since it is supposed to be platform independent. Therefor it just postpones the register-allocation etc, to the JIT compiler. (Correct me if I'm wrong.) So the Android guys thought, "hey, that's inefficient, let's go for a register based vm right away..."? But wait, there are multiple different android devices, what number of registers did the Dalvik target? Are the Dalvik opcodes hardcoded for a certain number of registers? Do all current Android devices on the market have about the same number of registers? Or, is there a register re-allocation performed during dex-loading? How does all this fit together?

  • A Program that sits in the Notification Area

    Hello, Thanks for taking the time to read my question. If I build a program, how can I get it to hide in the notifications area(windows 7, cant remember what it's called in XP or Vista) when I minimize it? Like say a Torrent program, or a AntiVirus program. Also I'd like to know, how can I hide it from the notifications area and bring it up when it a hotkey command is entered? Any clues on any of these two problems I'm having for an a program I am doing would be great. Thankyou

  • List Management Via MailChimp API

    - by goombaloon
    I'm investigating using the MailChimp API to manage email notifications for a social networking site (similar to how Twitter sends email notifications to followers when a followee posts a new Tweet). My original plan was to have a "follower" list for each user in the app and then send an email to that list each time that user posts new content. However, it appears that the MailChimp API intentionally doesn't support creating campaign lists via the API (for CAN-SPAM reasons). I've read something about list segmentation in MailChimp, but I don't think that helps me with this situation. I'm curious if anyone else has run into a similar requirement to mine and how they dealt with it. Any insights would be most appreciated! Thanks.

  • REST authentication internal project (iPhone to grails app) using 2 legged oauth?

    - by Rael
    Hi, I'm creating an iPhone project, and will be communicating with a server via REST. I will be sending push notifications, initiated from another service. I would like to authenticate all communication from the iPhone to my server (e.g., synchronising notifications with the server as the push request is not guaranteed to go through) 2 legged Oauth seems to be the ideal solution, however there is not a lot of information regarding it, especially as most of the libraries seem to be oriented towards consumers and not providers. What library should I use? Is Oauth overkill? If so what do you recommend? I'm looking for the simplest possible solution at the moment; If it is going to take me more than a week to implement Oauth, it's simply not worth it. Thanks

  • Popup Dialog Box Manager using PureMVC

    - by webwise
    I am developing a a game in Flash using the PureMVC framework. From time to time I need to show dialog pop-up window to get a user response back (e.g. "Cancel", "OK" and other kinds of asynchronous user feedback) while "locking" the background for interactivity. I need some management for my pop-ups: all pop-up notifications should be stacked up, so that if two (or more) pop-up messages are initiated at the same time I show them one by one. What's the best practice here? Should I employ a proxy to manage my pop-ups (sounds unreasonable). How do I get feedback back from my dialog? using notifications?

  • Add/remove UILocalNotification based on changes in my settings bundle

    I have an app that sends a notification at the same time everyday, reminding the user to enter data into it. However, I want to give the user teh option to disable this as this could get very annoying, so I have an "Enable alerts" in a custom settings bundle. My question is, when the user toggles the switch in the settings bundle, can I add/remove the notifications that are already scheduled without having to enter the app again? note: I'm building and supporting for iOS 4.2.1, and I don't konw why but under "notifications" in the settings app, my app does not appear. I see it on ios 5.x devices though

  • deadlock when using WCF Duplex Polling with Silverlight

    - by Kobi Hari
    Hi all. I have followed Tomek Janczuk's demonstration on silverlight tv to create a chat program that uses WCF Duplex Polling web service. The client subscribes to the server, and then the server initiates notifications to all connected clients to publish events. The Idea is simple, on the client, there is a button that allows the client to connect. A text box where the client can write a message and publish it, and a bigger text box that presents all the notifications received from the server. I connected 3 clients (in different browsers - IE, Firefox and Chrome) and it all works nicely. They send messages and receive them smoothly. The problem starts when I close one of the browsers. As soon as one client is out, the other clients get stuck. They stop getting notifications. I am guessing that the loop in the server that goes through all the clients and sends them the notifications is stuck on the client that is now missing. I tried catching the exception and removing it from the clients list (see code) but it still does not help. any ideas? The server code is as follows: using System; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.Collections.Generic; using System.Runtime.Remoting.Channels; namespace ChatDemo.Web { [ServiceContract] public interface IChatNotification { // this will be used as a callback method, therefore it must be one way [OperationContract(IsOneWay=true)] void Notify(string message); [OperationContract(IsOneWay = true)] void Subscribed(); } // define this as a callback contract - to allow push [ServiceContract(Namespace="", CallbackContract=typeof(IChatNotification))] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)] public class ChatService { SynchronizedCollection<IChatNotification> clients = new SynchronizedCollection<IChatNotification>(); [OperationContract(IsOneWay=true)] public void Subscribe() { IChatNotification cli = OperationContext.Current.GetCallbackChannel<IChatNotification>(); this.clients.Add(cli); // inform the client it is now subscribed cli.Subscribed(); Publish("New Client Connected: " + cli.GetHashCode()); } [OperationContract(IsOneWay = true)] public void Publish(string message) { SynchronizedCollection<IChatNotification> toRemove = new SynchronizedCollection<IChatNotification>(); foreach (IChatNotification channel in this.clients) { try { channel.Notify(message); } catch { toRemove.Add(channel); } } // now remove all the dead channels foreach (IChatNotification chnl in toRemove) { this.clients.Remove(chnl); } } } } The client code is as follows: void client_NotifyReceived(object sender, ChatServiceProxy.NotifyReceivedEventArgs e) { this.Messages.Text += string.Format("{0}\n\n", e.Error != null ? e.Error.ToString() : e.message); } private void MyMessage_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { this.client.PublishAsync(this.MyMessage.Text); this.MyMessage.Text = ""; } } private void Button_Click(object sender, RoutedEventArgs e) { this.client = new ChatServiceProxy.ChatServiceClient(new PollingDuplexHttpBinding { DuplexMode = PollingDuplexMode.MultipleMessagesPerPoll }, new EndpointAddress("../ChatService.svc")); // listen for server events this.client.NotifyReceived += new EventHandler<ChatServiceProxy.NotifyReceivedEventArgs>(client_NotifyReceived); this.client.SubscribedReceived += new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(client_SubscribedReceived); // subscribe for the server events this.client.SubscribeAsync(); } void client_SubscribedReceived(object sender, System.ComponentModel.AsyncCompletedEventArgs e) { try { Messages.Text += "Connected!\n\n"; gsConnect.Color = Colors.Green; } catch { Messages.Text += "Failed to Connect!\n\n"; } } And the web config is as follows: <system.serviceModel> <extensions> <bindingExtensions> <add name="pollingDuplex" type="System.ServiceModel.Configuration.PollingDuplexHttpBindingCollectionElement, System.ServiceModel.PollingDuplex, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </bindingExtensions> </extensions> <behaviors> <serviceBehaviors> <behavior name=""> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <bindings> <pollingDuplex> <binding name="myPollingDuplex" duplexMode="MultipleMessagesPerPoll"/> </pollingDuplex> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/> <services> <service name="ChatDemo.Web.ChatService"> <endpoint address="" binding="pollingDuplex" bindingConfiguration="myPollingDuplex" contract="ChatDemo.Web.ChatService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel>

  • Will there be IQueryable-like additions to IObservable? (.NET Rx)

    - by Jason
    The new IObservable/IObserver frameworks in the System.Reactive library coming in .NET 4.0 are very exciting (see this and this link). It may be too early to speculate, but will there also be a (for lack of a better term) IQueryable-like framework built for these new interfaces as well? One particular use case would be to assist in pre-processing events at the source, rather than in the chain of the receiving calls. For example, if you have a very 'chatty' event interface, using the Subscribe().Where(...) will receive all events through the pipeline and the client does the filtering. What I am wondering is if there will be something akin to IQueryableObservable, whereby these LINQ methods will be 'compiled' into some 'smart' Subscribe implementation in a source. I can imagine certain network server architectures that could use such a framework. Or how about an add-on to SQL Server (or any RDBMS for that matter) that would allow .NET code to receive new data notifications (triggers in code) and would need those notifications filtered server-side.

  • How does a custom accessor method implementation in Core Data look like?

    - by dontWatchMyProfile
    The documentation is pretty confusing on this one: The implementation of accessor methods you write for subclasses of NSManagedObject is typically different from those you write for other classes. If you do not provide custom instance variables, you retrieve property values from and save values into the internal store using primitive accessor methods. You must ensure that you invoke the relevant access and change notification methods (willAccessValueForKey:, didAccessValueForKey:, willChangeValueForKey:, didChangeValueForKey:, willChangeValueForKey:withSetMutation:usingObjects:, and didChangeValueForKey:withSetMutation:usingObjects:). NSManagedObject disables automatic key-value observing (KVO, see Key-Value Observing Programming Guide) change notifications, and the primitive accessor methods do not invoke the access and change notification methods. In accessor methods for properties that are not defined in the entity model, you can either enable automatic change notifications or invoke the appropriate change notification methods. Are there any examples that show how these look like?

  • AVD Failed to Load ~ Failed to Parse Properties ~ Mac OSX

    - by C.D. OKeefe
    I'm going to say upfront, please forgive me. I'm a newbie to android development and fairly new to programming. Also on a Mac. You're going to have to talk...real...slow. I can't get an AVD to load. I've tried it from Eclipse and from the Android SDK Manager. Failed multiple times. Received the same error each time, "Failed to parse properties from Users/myname/.android/avd/nameIGaveEmulator/config.ini." I've the forum here and saw that others have had similar problems, but of the answers given, no one came back to say if they worked, and I don't see anyone with a similar problem on a Mac. If the path needs to be "changed" what exactly does that mean and how do I go about doing so?

  • Google checkout - Order processing notification handler

    - by Kunal
    Hi I need to integrate google checkout on my website. I have successfully implemented the order placing and others stuff and using the sandbox I have tested that users can successfully add items to cart and and pay thereafter. I am using my own customized shopping cart written in php mysql. The last thing I need to do is pass the new order id to google checkout and receive notifications with the new order id as well as other data google sends. I know I have to setup a path to the handler script in my accounts. I did it in my sandbox account as well. But can't find a simple pice of code to get it done. Even if I use sample code from google, just cant figure out the format of the returned data in new order notification and also how to send custom data to the cart, which would come back with new order notifications? I am just lost on this. Please help!
