Will there be a formal annoucement about the lucky book winners?

Though this is not related to tech discussion going on here, I thought it might be useful for someone looking to buy an Android phone

G1 Android phone from Amazon.com, 97.99 + 2yr contract
http://www.amazon.com/T-Mobile-G1-Phone-Google-Black/dp/B001JT1U1E/ref=pd_bbs_2?tag=slickdeals&ie=UTF8&s=wireless&qid=1236702869&sr=8-2

Anyways, the deal is straightforward, $97.99 for each phone if you sign on for a 2 year contract.

From Amazon.com: "The purchase price listed above reflects a $250 instant discount based on your agreement to maintain service with the selected carrier. Please note that if you deactivate this device, cancel your line of service, or reduce the value of your service plan within 181 days of the activation of your service, you will be subject to a charge of up to $250, plus tax."

I also heard that you dont need the Data plan if you want to use the wifi only you can without the data plan just buy the data plan for the first month and set up your phone and cancel the auto synch and it will work without the data plan

Hi Devender,
Thanks for that.

Sorry I should have noted that qstn #2 is not an example for qstn #1. Will edit the post now. Thanks.

Devender Thareja wrote:Hi Sri,

The example you have provided is simply a web application and it should work on all devices. This is not an Android app. Android app is written using Android SDK.
Similarly Blackberry has its own Java based SDK. You can architecture your app to reuse most of components but GUI part will probably need to be rewritten.
Iphone SDK is not Java based, hence there will very little re-use of work done on other devices.
I don't have knowledge of Symbian.

Thanks.

I have a questions:
Once an app is written in Android, how easy it is to port it to phones using other O/S (like Symbian, iPhone O/S or BlackBerry)?


(edited to remove an unwanted question)

You can access other enterprise applications from with in your Android phone, provided it meets the security policy setup in your network where the application resides.

As far as running an enterprise wide application from with in Android, i would say it is a over kill.

As per my thinking "NO".

Wat do you guys say?

What type of applications we can deploy on Android?

Seems like there are already some form of secure tunneling that is available that can be made use of:

Also seems there is this product/dev solution out there that provides VPN capability for Android phones.

Ed, I already found that articles on REST and some on SOAP. Thanks for that.

Regarding VPN not being supported by Android, is it the current limitation that could be overcome in future releases or it was a conscious decision to not support VPN?

Ed Burnette wrote:As long as you can get access to the ERP application through some kind of external web service then you can do it. REST and JSON are built-in, but with some extra work you can do SOAP (search this forum for links).

If your network requires both the client and the server to be inside a firewall then no, because VPN is not currently supported. This is one difference between the Android and Blackberry platforms right now. A Blackberry device can access intranet resources and sites just as if you were sitting at your office desk.

Hi Ed,
Can your book be used by a novice like me?

Ed Burnette wrote:Initially, you may want to invest in an introductory book on Android development. There is a lot of online information available but much of it assumes you already know what all the pieces are and generally how they fit together. It will make a lot more sense to you once you go through a well-written book.

After that, I suggest working through the online tutorials, especially:

http://d.android.com/guide/tutorials/hello-world.html
http://d.android.com/guide/tutorials/notepad/index.html

The online documentation from Google is great if you know exactly what you're looking for. And people are always posting great tutorials and how-to articles on http://www.planetandroid.com .

I am currently working on an major ERP application that is widely used (sorry, due to employment clauses i cannot reveal with ERP product and the targeted vertical). We are currently thinking of leveraging Adroid to enable users to do simple tasks from their mobile devices. For example, approve a purchase request or to approve a timesheet etc.

How good is Android in this area? Is it mature enough now to support this kind of applications?
(I am pretty new to Android. So pardon me if my question is silly.)

Thanks.

(I have already searched this forum to see answers to similar kind of questions.
I found that answers by Peer Reynders, Ulf Dittmer and others were really helpful.
But I still feel I should post this direct question to everyone. Sorry if you think this question is a repetition)

I am looking for good books on SOA/Web Service from the perspective of a Java Developer trying to learn SOA/Web Sphere.
I managed to find good books written by SOA Guru Thomas Erl, they seem to be targetted for those already experienced in
SOA/Web Sphere and intended for architects.

Though I found the following books that meet my criteria, they seem to have not received well by developers new to SOA/WS.

Service Oriented Architecture with Java: Using SOA and web services to build powerful Java applications by Binildas A. Christudas (Author)
SOA Using Java(TM) Web Services by Mark D. Hansen (Author)
Java Web Services by David A. Chappell (Author), Tyler Jewell (Author)
Java Web Services Architecture (The Morgan Kaufmann Series in Data Management Systems) (Paperback) by James McGovern (Author)
J2EE Web Services by Richard Monson-Haefel

Is there any book, that you would recommend for a Java developer trying to learn SOA/WS with easy to understand examples?
Something in lines of building a SOA/WS based application side-by-side while reading this book.
I am strong in Java, XML etc but I would call myself a novice trying to learn WS

If you think any of these books that I mentioned might as well help, please let me know.

Thanks.
