I want to create a limited version of my app on mobile.
My app is at www.accountingguru.in (appid: accountingguru-india.appspot.com). It is using Servlets/GWT/Objectify 3.1
I am figuring out how to move forward with the design/development choices for a limited mobile app
What is a good url for Mobile User experience.
www.accountingguru.in/mobile
mobile.acccountingguru.in

It can be both if you properly set your domain names (and GAE mapping) and use some url rewriting. The first option might be easier from the authentication perspective.
If you use GWT/GAE it needs to be a common project if you want to have one GAE instance. In practical terms you can not have two different GWT projects and upload them to same GAE instance. As far as GWT goes - you can have two separate entry points: one for desktop and the other for mobile browsers.
You can have same url.
Use deferred binding to achieve different UI according to user.agent
Define a module .gwt.xml to detect the user.agent
On your applications's module use the return value to choose the appropriate implementation.
Have a look at the sample projects in gwt.

This is the first time i'm working with firebase. My goal is to have a bounch of client apps (more and more over time), all of them managed by an admin app (One app to rule them all).
The thing is that the client apps have a certain content that needs to be updated from the admin app. My best approach is to create a firebase project, put the admin app there and adding client apps over time. I'have read that is possible to have an unlimited number of apps inside one Firebase project. On addition, someone told me to create one project for each client app and connect them to the same database somehow. I simply don't know what to do.
Which would be the best solution for my problem? thank you
firebaser here
A Firebase project can currently contain up to 30 app definitions. This is meant to support variations of the same logical application. For example, having an Admin app in addition to the app for regular users, and/or having an iOS, Android, and Web version of the same app, and for example having a free and a pro version of the app (if that is allowed by the stores where you deliver them).
Adding multiple apps to a project is expressly not meant to be used for white labeling apps, where you ship essentially the same app with different branding to different user segments, as you'd be sharing the backend services between them. For some backend services (such as database and storage) this is not necessarily a problem, as you can isolate the customers with security rules. But for other services (such as authentication and analytics) this is not possible, which is why this use-case is not supported.
If you need to define a separate app in the project for each customer, the only supported approach is to create a separate project for each customer.
I'have read that is possible to have an unlimited number of apps inside one Firebase project.
In that case please provide a link, so we can either fix it, or (if it's not in the Firebase documentation) leave a comment to clarify.
I have an standard appengine app currently running. I am currently developing another flask app which will use flexible runtime. I am wondering is it possible for me to have both apps in same project?
Yes, it is possible, with each of your "applications" being implemented as separate services/modules in the same GAE app. Services/modules offer complete code isolation, see Comparison of service isolation and project isolation.
See also: Custom runtime for non-flexible environment app?
There is an even easier way to do this that doesn't require creating a separate service :)
Since you are only developing your second application, you do not need to set it as the default version to serve traffic to the public. You only need to access it yourself, (or perhaps whoever you give the URL to). The only drawback really is that you will not be able to access your project at the default url, usually .appspot.com
Therefore, you can simply deploy your flexible app engine project, but make sure you don't give it any traffic sharing or promote it to the main version!! You can then access your version simply by clicking on the version in the google cloud console, or by visiting http://-dot-.appspot.com/ (It was not possible to access individual versions like this for flexible for quite some time, but this has now been resolved.)
We have a running multi-lingual app hosted in Azure written in AngularJS. For managing some of the unsecured/public pages, we are looking for hosting another app with a CMS. So our app structure is would look something like:
App: www.example.com
CMS: www.examplecms.com
What we want to achieve is that dynamic content generated by CMS (different domain) for static pages be served using urls in www.example.com. Is it possible? We are primary targeting .net based CMS solutions but are open to other platforms. The static content is not too complicated.
Since the app supports multiple languages and most of the CMS solutions available offer multi-language support via subdomain.example.com or www.example.com/language/ directory structure, we want the custom url redirection to point to our app site (www.example.com).
Looking for suggestions you opinions or best strategies to work around this problem.
This Q is off topic, nether the less...
As you would essentially be running 2 entirely different web sites, yes everything would work just fine. The requirements are vague and very generic but any application/CMS could be setup in different domains and if you wanted requests made between them, allowing cross origin requests would allow sharing content/data.
Umbraco, like many CMS's supports multilingual sites using path prefixes as you mention along with any other method you are willing to write yourself.
I'm in the process of making an app for my assessment at uni using cordova/phonegap and was just wondering if its possible for me to use data from a my unis ecom website for my app without having any back-end access to it, so like images/prices/descriptions...synced to my app?
yes it is certainly possible, because Cordova means working via Javascript and a HTML5 Rendering Engine. It is with some reservations entirely possible to load data from an webserver and use it in an App.
The only thing is to ask, whether it is also a smart-choice. If you want your app not to break when the data from the website gets changed (see https://en.wikipedia.org/wiki/Link_rot )
Also the server can somewhat prevent access of data from contextes outside of the webpage, especially if TSL/HTTPS connection is offered and content is only available after authentication.
Yet anyway its the magic of Javascript to be very good in doing things with web/online resources and displaying HTML5. Cordova and PHonegap is hence imo much better than the very challenging JAVA-Dalvik and IOs native programming that one would have to use else
Likely not,
Google and Apple frowns on using apps as wrappers for websites.
Quote Google Developer Program Policies - Spam and Placement in the Store
Do not post an app where the primary functionality is to:
Drive affiliate traffic to a website or
Provide a webview of a website not owned or administered by you (unless you have permission from the website owner/administrator to do so)
And
Quote Apple iTunes Guidelines - 2.12
Apps that are not very useful, unique, are simply web sites bundled as Apps, or do not provide any lasting entertainment value may be rejected
Is that somehow possible to access one datastore? Or access one app from different domains.
App Engine recently add support for a feature called modules (Docs: go, python, java)
App Engine Modules (or just "Modules" hereafter) is a feature that lets developers factor large applications into logical components that can share stateful services and communicate in a secure fashion. An app that handles customer requests might include separate modules to handle other tasks:
API requests from mobile devices
Internal, admin-like requests
Backend processing such as billing pipelines and data analysis
When you create a new module, App Engine will create a url that corresponds to the module name. If you only have one module then the name will be default. e.g.
http://default.myapp.appspot.com
http://mobile‑frontend.myapp.appspot.com
http://my-module.myapp.appspot.com
Using Domain masking, you could then direct from:
www.myapp.com => http://default.myapp.appspot.com
www.myapp-mobile.com => http://mobile‑frontend.myapp.appspot.com
www.example.com => http://my-module.myapp.appspot.com
Every app has its own datastore and memcache (shared among all versions of that app).
It seems not possible to share datastores between applications right now (unless you provide some web service for that), but that would be a nice feature to have, so maybe you should file a feature request with Google vote for it.
As for domains, you can associate your app with domains managed by Google Apps. Multiple domains for the same application should be no problem (except for SSL certificates).
Every version of an app is backed by the same datastore. If you want to limit access for individual requests, you'll need to add a field to your model to enforce that restriction. There are low level hooks in the datastore API for this sort of thing, if you want to go that far.
And yes, you can add a single App Engine app to multiple domains - even in multiple Apps accounts.
Kyle's solution would work, but App Engine was never designed to be used in this way. So if you architect your app(s) to rely on this kind of setup and Google clamps down for whatever reason then you'd be screwed.
You can have multitenancy using the Namespace Java API
