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

I have a relatively small Java app, which I'd like to move over to the Google App Engine. It runs in the console, with no user input needed after the initial startup. I researched a bit on how to deploy it, but all tutorials seem to focus on Java web apps, when I don't really need that. Is it possible to deploy my app if it's not a web app?
App Engine is probably the wrong GCP platform for you - you'd probably be better served just deploying your jar directly onto a Google Compute Engine node. GAE is pretty explicitly oriented around web applications and you'd need to do a bunch of configuration in order to have it work for your use case.
Does your non-web Java app handle web requests? If not, it seems difficult to imagine that you would be able to reach your deployed app and use it for any purpose, once deployed. Your Java app should be able to handle requests, to make deployment worthwhile, and the deployed app useful.
You may find out about how your app should handle requests by reading the How Requests are Handled documentation page.
I want to create a mobile backend with Google App Engine on Google cloud problem.
I want to develop a Java Servlet that accepts image file and performs some image processing effects (tint,blur, ..) on it.
I'm wondering if there are any libraries that can be used for such a scenario.
Can I use something like OpenCV for example, or I will have to implement the effects functionality from scratch?
Actually, App Engine has a built-in Images API for Java that supports a bunch of different transformations. It may not support everything you're looking for, but it's a low-effort starting point.
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.

Can I use GAE(Google App Engine) for developing a server for mobile clients? Mobile clients will send data to server every 10 seconds.
I am planning to develop the prototype using GAE and then depending on the results, will decide where to locate the prod server.
And are there any best practices to follow in developing code so that it will have very minimal dependancy with GAE (Can easily port to another environment with minimal code change when required)
thanks.
Ofcourse you can, GAE provides a good way to create a great backend for a mobile app.
about dependencies, you can use a project like django-nonrel, it creates an interface between your code and the API of GAE.
Does anyone know if it is possible to read from a Datastore on the app engine to a native app?
I am working my way through making a simple notes app that I can store online and use on my phone and tablet. I would prefer the phone interface be more than just a WebView instance or only used from the browser. I would also like a tablet optimized version as well.
I am comfortable programming android, and I am comfortable with web apps as well, so this is the last important piece before I can start putting it all together.
Has anyone done this before? Or, if it isn't possible, can someone send a link so I can further explore and find out what?
Thanks!
You can interface directly with the datastore using remote_api, but this is designed as an administrative interface, and shouldn't be used for access by end-users. The standard approach for what you're doing - on any webapp, regardless of platform - is to define an API that your application exposes for access to the data, and consume that API from your native app. If you're using Python, you may want to check out ProtoRPC (now included in the SDK) as an easy way to define APIs.
