Node.js seems like a perfect solution for creating an API for my Android application. I want it to be hosted on my own web domain, without using any commercial solutions like Heroku, Firebase, AWS. Running server on localhost seems pretty straightforward, but finding a solution on how i could host it on my own server is a problem.
When purchasing your own domain, what should you look for in terms of supported technologies when you want to host Node.js application, using a MongoDB database, that also has to deal with great amount of media stored? Is there any alternative that doesn't involve using cloud solutions, but creating your own back end solution that allows being in total control of your hosted content, what is installed and how it works?
Probably you can use a VPS (Virtual private server). You can have your own Operating system installed, and manage it as your own machine, installing everything you need, and publish there whatever you want.
I have something like you are looking for with OVH (check it here https://www.ovh.es/vps/vps-ssd.xml). I think they have one of best prices and it works fine.

I'm using the firebase-ui-android authentication flow for my mobile app.
I would like to do the same for my desktop app, but it doesn't seem like there is an equivalent framework; the closest seems to be firebase-ui-web.
Now I'm playing with the idea of (ab?)using firebase-ui-web to run locally on the client machine for authentication.
However, since firebase-ui-web seems to be aimed at the server I'm a bit wary running it on the client side.
The desktop app is fairly simple, it pretty much only needs to read some firestore data.
What are my options here?
The only ways to connect with Firebase are by an Android, an iOS and a web app.
There is no support for desktop apps.
But, you can create a native sync service to link your desktop app with Firebase users throught a web service.
It is feasible to have a desktop app to connect to Firebase. However you should create a hybrid desktop app using electron or other platforms that is by nature use web and javascript. Here is an example of using electron to manage firebase: https://www.electronjs.org/apps/firebase-admin
You can use Google Sign-In for TVs and Devices for that case.
This is not perfect, because you need to use additional access code, but it can work with desktop applications as well
I would like to ask you for an opinion about best free/paid server solution for the server side of android app. The server is written using "Restlet". I need application server with MySQL backend support (like "TomCat" & "MySql" on my local machine). I would like to upload the app on GooglePlay for free so i cant afford something expensive. The applicaiton is language learner and the transactions are mostly pushing and pooling words so i guess i dont need huge bandwidht and so on.. Thanks!
Google App Engine now supports MySQL, and you can write your backend in either Java, Go, or Python.
I have deployed Android apps that use App Engine for the backend. Even with 30,000 active users, I pay $2.10 per week.
You might be able to squeeze into the free tier, and not pay anything at all.
Not sure if this is the correct Stack Exchange website but here goes..
A client has asked me to look into the possibility of having a iOS or Android App for typing in information storing that in a SQLLite database and then syncing up with the main desktop application when plugged in by cable or something other syncing technology.
The desktop application is a Windows one written currently in Delphi 7.
Are there any API's to sync data from a SQLLite database on iOS/Android that Delphi can use?
If not, then would it be better if the desktop application was written in C# as its a newer language that can consume the API's easier?
For unidirectional sync (device to desktop), I would start with a simple web service (HTTP based). The new Web Sockets standard, also based on HTTP, is a little more complicated, but would allow for bidirectional communication.
The devices can HTTP POST database changes to the server, and the desktop client can pull new data (using HTTP GET) or receive push notifications, for example using a Web Sockets client.
For desktop to device you could also check out Apple Push Notifications and the corresponding Android technology.
For high availability I recommend a cloud-based solution like Amazon Elastic Compute Cloud (EC2), Google App Engine (GAE) or Azure.
This question is rather broad, there are many things you could do here. There aare so many technologies to use it's blinding.
The prevailing technique for transferring information from mobile devices is REST (over http).
You could also whip something up rather swiftly in node.js or WFC to create a service to collect information from the mobile devices.
I'm not sure about Delphi libraries available but perhaps by including REST in your search term you may have more luck. You may want to take a look at https://stackoverflow.com/questions/3959851/using-rest-with-delphi for a start.
The mobile side may be more tricky. If you are developing for multiple devices you may wish to explore the cross platform developer framework by PhoneGap as there seems to be a few projects that aim to sync local databases to the cloud. How you tie these together will be an interesting task.
Good luck!!!
I'm planning a mobile app, to be built using phonegap, that will sync user data with a server. The data can be edited on the app or via a web interface on the server, and some users will have multiple devices so need to sync to them all.
Anyone know of good guidelines/tutorials/patterns for this sort of thing? I can hand-code it all but I'm sure I'll make lots of common mistakes and it'd be better to either use a library or follow some good rules.
If I was doing the server in java then something like OpenMobster sounds good.
have you checked out the Sync Framework Toolkit?
I am looking to do the same thing and have found https://github.com/orbitaloop/WebSqlSync/. I have not used it in anger yet, but it looks good.
Just so that there is no stone left unturned in your research.
To use OpenMobster your server does not have to be in Java. It helps if it is, but you can have your server in any language or platform. All you have to do is expose your data via a secure REST API.
You then write the OpenMobster Sync Channel that accesses data via this REST interface. Yes, this Sync Channel has to be written in Java as it plugs into the core Sync Engine.
So architecturally speaking, you would have the OpenMobster server between your server and the mobile device.
This is the same architecture when mobilizing legacy databases, CRM systems, ERP servers, SalesForce.com, etc
Full Disclosure: I am the Chief Engineer of OpenMobster project
I'm new to Android programming. I have a website with sql 2008 db, and now i would like to give the users the ability to use their smart phones to enter data to this db.
I was wondering what is the best way to establish it. Since I'm new to it I don't want to build something that's not so professional.
Thanks for your help.
If I were you I would consider two following options:
Have a web application optimised for mobile use;
Pros:
Updates are delivered immediately, as there's no client application, everything is done on the server;
Web application can be used on many devices with a browser and not just Android: iPhone, Blackberry, PC, Mac, etc.;
Cons:
Users need to be online to work with the application;
You can not leverage from the native UI components available to native device applications;
Write Android application that will work with the database via a number of REST endpoints exposed through a web application (again);
The pros and cons are a full reverse of what you had in the first option.
The right answer for me was to use KSoap library. I'ts very easy and works very well.
Here is a tutorial that will show you how to do it step by step.
