I have a Google App Engine application with a front-end that was created using GWT. How would I go about creating a mobile app equivalent of this? In particular I would prefer to use GWT to create the front-end here as well. Does Google have any thing within GWT specifically designed for creating mobile apps? Is there already some existing structure in GWT which takes the front-end you've created and makes it scalable so that it can be easily transformed into a mobile app? Thank you much!
You should also definitively check mgwt + gwt-phonegap. It's a cross platform gwt/phonegap solution.
It depends a lot on whether you wish to build cross platform as in phonegap or keep it simple as in mobilewebapp example provided in sample folder in gwt zip file you download.
The mobilewebapp sample does not access smartphone features but will be accessible by browser on any mobile. phonegap or similar frameworks like titanium,sencha provide api to access smartphone features.

So after too many searches I decided to ask this question.
First of all I'm building a mobile app using angularjs in my website (Online) not localhost. The app is a kind of a CRM based (CRUD mostly).
I have the cordova mobile application ready. I have a few questions here.
Is it acceptable, if I use the website URL directly in the inappbrowser URL (Like an iframe)?
Or. Should I need to put the angularjs files inside the www directory of the cordova app and access the server functions via API?
Which way is preferable? Why?
Will there be any performance differences?
If the No.1 is not a best practice, what is the major drawback on using the inappbrowser?
You can build Hosted Web App in an Apache Cordova:
For this scenario, you use a thin Cordova client (think of it as a web
browser embedded in a native app) that automatically redirects to your
Web site.
See also: Wrapping an existing web application in Cordova.
Other option: PWA.
From Wiki:
Progressive web applications (PWAs) are web applications that load
like regular web pages or websites but can offer the user
functionality such as working offline, push notifications, and device
hardware access traditionally available only to native applications.
PWAs combine the flexibility of the web with the experience of a
native application.
I am trying to build for website so I need to know that.what is progressive web app? and all devices or only moniter.
Progressive web apps are web apps that can look and act like native apps.
django-progressive-web-app may be a good place to start your research about using Django for your project. I've never used it myself, but it looks promising.
Say I have an existing mobile app built on Ionic. Now I need to have a website version of the app so users can access it via desktop too.
Is there any documentation that suggest this is possible?
I think you're looking for Progressive Web Apps. Ionic does cater for such, just google for the term "Ionic PWA" example below.

I'm confused about these technologies. Actually i want to build a mobile application with SQLite database for offline as well as should support webApi services or something. So it should support both SQLite and server which targets IOS, Android and windows.
I did some R&D and gather some knowledge about cordova and angular.
I like to use angular on my mobile application so that i can manage my client side data and app flow easily and wisely.
Now i'm confused whether to use cordova or phonegap or ngcordova (which i recently came to know that it exists).
As i mentioned, i want a mobile app with SQLite and support webApi services and also should support multiple platforms.
So now where/how to start and which is best one for me. i'm developing this app for production i mean real time app.
please help to start with.
This is my email id jprasanth74#gmail.com if you have any guide please share it..
Cordova is use for create build in different platforms
you have to start write code in angular.js
just use this sample link
https://blog.nraboy.com/2014/09/implement-barcode-scanner-using-ionic-framework/
to create first app and send me your email i will send you the startup guide line to create enviroment with cordova and ionic framework
ionic framework is support angularjs and cordova both in one package and it is very faster then other framework
http://ionicframework.com/
just dive me the email address i will send you the basic startup
to all
as we all know, Appscript tipicaly for Google Spreadsheet now have a UI builder, though you can compose UI with the script itself the builder is a big factor. now
GAS application is hosted in google drive and can be either share or publish as Webapp. which is great but this type of app is very limited to storing your data in a spreadsheet well, designing a good DB spreadsheet would be enough for small application but is NOT scalable for SME to Enterprise apps.
now having google app engine which have a very good and scalable platform for a webapp.
is there anyway to port the UI library capability and use it for app engine application. having GAS UI as a javascript base (client side) it could be integrated with any serverside language in GAE.
do any one have any example on this or is it now posible?
the way I see it this might be the future for GAE having a GAS as a client side library would be great?
Well, I think you should be looking the other way round. All of Apps Script's UI widgets are borrowed from GWT in GAE. In fact, the Apps Script documentation, at places suggests that we should lookup GWT documentation when this is found inadequate.
Coming to the point of the UI bilder, I'm no GAE expert, but since you get a GWT toolkit for Eclipse, you should be able to use any of Eclipse's UI creating tools ( I may be wrong here).
GWT is compiled to javascript. It doesn't care what the backend is. You can use json to communicate to your python AE instance just fine I would think. I do GWT on java AE so don't have an example of my own but here is an example of using python on AE to use App Scripts https://developers.google.com/apps-script/articles/appengine
