Basically my android project is around making a form to be filled up by the user of the app. And send this data to the php server. The data may be collected offline so the app should also save the datas unless its in the reach of wifi or gprs network. I'm early beginner to android and got stuck in between. Can any one suggest me a similar project sample so tat I could make a study and learn the stuff.
Sounds to me like a good use case for a hybrid client-server app. Use the mobile device to collect forms and store their results in a SQLite database. Whenever an appropriate wireless network is available, connect up with the server-based app and upload all the data. There are many good ways to do this, but for starters, consider making the server app implement a RESTful API and have the mobile device use this API to send in the data. If messing around with a server sounds like fun, I've had good luck with MySQL + CakePHP. One of the cool aspects of CakePHP is it gives you RESTful access to your database almost for free. Or, you can use something like Google App Engine and let someone else worry about administering the server.

I want to send some data:
Database ==> server ==> app
I don't know what type of communication to use.
Restful api ? Tcp ? or just get request ?
App will get the data and display it in form of individual posts.
The server is in django with PostgreSQL, and the app is in react native,
There will be a couple posts a day(containing text and link to a image hosting on the server). The app doesn't need to store anything offline.
This is a very complex question, in the sense that it covers a great vastness of architecture. There are many approaches to implementing a solution. The question is very general, therefore we should understand in detail what the app does, what its functions are and the data it manages, the frequency of interaction with the database, if it needs changes and much more. However, on average, a solution that lends itself to these technologies is the development of a web server to manage RESTFUL calls. In such a way that services are exposed and the app can safely make calls (for example a CRUD) and manage data to your database. If you better enter some specifications we can analyze in detail a possible solution.
I want to create a web server at home and upgrade it to communicate with my Android app. Eventually I would like to store SQL data on it and collect data from it in my Android app. I have no idea where to start, and I am worried that I might start with one tutorial which will eventually not be able to give me the end result I want.(I am looking for tutorials at the moment since I have no knowledge on server side coding or anything similar)
So I was wondering if XAMPP is the thing I am looking for? I found many tutorials on that but I can't find anywhere if it is possible to eventually store my SQL data and communicate with android app. Also I read that XAMPP is for testing purposes and I would like to start learning something I might actually use as a web server later on for commercial apps.
If not, what else can I use? Many websites suggest JSON server communication but I am still not sure if that is the thing I am looking for.
Install xamp on your pc
Create the php file to communicate with the android data
Use http://10.0.2.2:80/ as a server ip in your android project

I am trying to create an android application in which an user will pretty save some data in database-like user data, photos and also be able to retrieve.
But I am clueless how to set up a server, connect to some database etc.
Can somebody help me point to right resources for end-to-end installation of server, database, and its interaction with the android application
Just set up a basic server that works over HTTP, and use HTTP libraries for android to make requests and handle results in the device. There are plenty of technologies with which you could make the server, just google building REST API with PHP/.net/java (whichever language you are comfortable with).
If you are mobile app developer and want to create server-client app then better use any back-end service rather than implementing new by own. Some most advanced and simple to use services are Parse and Firebase , BaasBox also there are many more.
And the plus point is this services free of cost until you have very large users.
I have already an location based app which functionality i want to expand:
A user can login to this App via Facebook and also other users are logged on their own Mobilephone. Both can see the location of the other.
So basically an location aware meet people APP :-)
How can I do this? Backend with PHP and mysql database?
Are there already existing solutions I can use?
Tutorials available describing this?!
the infrastructure you need is achievable in many many programming languages and many types of databases.
In the end what you need is a server running that can store the location data sent from the users. Ideally i would tell you to use webservices in order to achieve this.
Next, you will need to implement a location service app that works on the user smartphone and uses the web services to send information and get information to and from the server.
Programming languagens you can achieve this are so many. For example, in the back end you can use a mysql database with a tomcat server. if u need a front-end for the server you can use java server pages, php, whatever u feel more confortable with.
for the mobile phone there are hybrid application for different OSs. for android specifically you will use java. if u want to save some info in the phones you can use a SQLite database. this is important if you want to send data only when internet connections are available.
Those are the kind of things you have to deal with. Hope i helped you.
Good luck.
I need to build Android application using Java which is able to send request to read or write some data to "database" or similar data store on google web server (using GWT technology).
Android app should be able to authenticate user with Google Account, send request to server to add data to database on server, receive data form server.
I would like to know what is the best approach and architecture I should use? What mechanism should I use to get data response over network (RPC, GET request)? What should I put on server side (servlet, ...) ?
There is example how to build gwt app: which run 1. javascript in browser 2. servlet, service, serviceImpl, serviceAcynch, etc... I think this is no use for my app because I need to directly get and send data to/from server.
I need to have data exchange with GWT server to get/update coordinates for my Google MapView. Therefore I need to use data exchange mechanism between android client app and GWT.
Why do I need this on android? I have to be able to get GPS position of android device and update data with web server, then display my android device position on map. I need GWT to store, put, return position data (for example to show visited locations). Should it be build as Android native app? How can I update, get data from GWT server?
You've asked a general question. The best I can do is give you a general answer. For stuff like this, I like to build up a REST framework. REST is a robust and resilient paradigm which is something you need when developing mobile applications, the network connection could go out at any time. Using REST, you can just use standard HttpRequests to query the server. Responding to the requests server side is as simple as processing the HttpRequests. On Android, the HttpURLConnection class is perfect for this kind of stuff. If you want a rather complex but comprehensive example of all this, you can take a look at the SampleSyncAdapter example in the android SDK. Also, you might find this Google IO video interesting. It's one of my favorites.
