i know very well that android not support the mysql
but i need to connect mysql and get the information from database
i studied there are SOAP and REST services to connect mysql from android
is it possible?then give me one idea and if possible one example pls
i need to connect mysql and get the
information from database
You can get the data from the database with or without connecting to it. You can get it with or without SOAP. An agent on the server, usually a CGI sript makes the database request on the client's behalf. In SOAP, the the query and response are often encoded in XML, and always transmitted by standard Internet methods such as HTTP or SMTP.
Non SOAP methods include CORBA, simple RPC, and home-grown solutions. If the database is open to the Internet, then a direct connection to the database port on the server is possible.
It's only the security restrictions that limit what you can do. In an environment where only mail, HTTP and FTP are possible, SOAP is a good protocol. If the client is actually a web browser, then AJAX is ideal.
For a typical data request, all you need to know is the URL (and associated protocol) on the server to query for the data. For example, using HTTP:
http://dataserer.example.com/chart_data.cgi?chart_num=2
The server-side script, chart_data.cgi reads the query (from a GET request in this case), retrieves the information from the database and sends it, encoded in XML, back to the client, simply by writing the HTTTP header and XML content to standard output. It is Javascript and a browser protocol XMLHttpRequest that make the HTML request and XML receipt possible.
So even in Android, when you browse the web and see all that information, on Amazon for example. A lot of that information is retrieved by agents at Amazon from their database, formatted for the client(the browser on Android) and sent back to the client. No Android-specific coding is required.
Use a custom remote agent such as a CGI script on a server to access a remote database. Android only needs to communicate with the agent.
Write a SOAP server using the language of your choice:
Google: Soap Server
Call it from Android:
How to call web service with Android
Of course, you don't have to do it in SOAP. You can just output the data from your web service in any format like JSON, plain text, XML, CSV, (or even HTML?) ... and consume it from Android.

I'm developing a website and mobile application that communicate with each other.
It's very basic at the moment: the app makes a get request to a URL and the server returns JSON data.
I want to secure this and make sure no-one can send a get request to the URL and get this data (only the website and the app). Is it ok to make a 60+ character password that the app can send with the request that the server accepts before data is sent, or is this breakable?
I dont want to use OAuth because it's overkill as only the app and the site are going to communicate. Please provide me with a few solutions, thanks!
You can use HTTPS to transmit data.But you will need an SSL cerificate for this.
Usually, when you send an e-mail (with Thunderbird or Outlook), you don't send it directly.
example: I have a gmail address and I want to send an e-mail to a myopera address. The process will be:
user->gmail server(gmail-smtp-in.l.google.com)->myopera server(in1.smtp.messagingengine.com)->final user who'll download it's email with pop/imap.
One of the inconvenient is the size: Imagine you have attachment of 50Mb: the limit of myopera is 60MB; but the limit of gmail is 25MB,So the mail will be refused whereas it would be accepted if it was send directly to myopera.
But I saw with telnet that, it is possible to send mail directly with SMTP commands.
I want to write a client-side Only web application which would convert a mail in a set of SMTP commands for sending it. I should be very basic and not support encryption
I don't know how to create a TCP connection from a client, so, here's my questions: Does a library already exist? If not, what I should use? I've read about the existence of WebSockets but that Ajax would be more universal.
Also, most of the actuals implementations of WebSocket I saw, don't work in my latests versions of web browser despite the fact they 'support it'. There's also the raw Socket API from the W3c (I've no idea of the web browsers which actually support it).So, I would like to not avoid statements telling it is impossible to create near raw TCP/UDP session. Since it is possible, I can't imagine nobody created a kind of library for dealing with protocols
You should take an alternative route.
If i had that issue i would still use a server side component of some sort, and just have the server contact to receiving mail server directly.
Given the email: "someuser#somedomain.tld" you could do a DNS MX record lookup on "somedomain.tld" and find the receiving mail server say "mail.somedomain.tld", then you could tell your mail send component to send the email directly to "mail.somedomain.tld", that way you would have an immediate feedback on whatever the mail went through or not.
For Objective-C you may use https://github.com/jetseven/skpsmtpmessage
By looking at the source you see how SMTP works.
I understand how Database Table Authentication or Digest Authentication or HTTP Authentication works given the examples provided in the documentation. I would like to authenticate users to my application using Zend's \Authentication\Adapter, but am unsure how to do that by accessing a JSON Server rather than a local database.
Our users will pass their credentials into the application via a web post, and the application will send any and all request to a separate service via JSON to authenticate, query, etc. I have no problem hooking into the JSON Server, and writing the requests, etc. for that.
What I'd like to do is use Zend's built in Authentication mechanism to hook into the results returned by the JSON Server. Is there a way to do that using JSON rather than Database Table Authentication or Digest Authentication, etc.?
Thanks for any insights!
You should write your own adapter, implementing:
Zend\Authentication\Adapter\AdapterInterface
Take a look at the other adapters for instiration
whenever, i request to server using jQuery-ajax for retrieve data that is shows in firebug so that is unsafe or hackable.
even facebook and google+ hide their json data, but how?
You could use a library like crypto-js to encrypt all data that is sent to and from the server. However, most of the time, that is an overkill when you already use https (since you should make your application hack resistant via server side validation and safety is ensured by the real encryption offered by https).
I was thinking that I needed more secure ways to transfer data between my app and my server on Heroku. I'm worried about MITM attacks. Then I noticed that the web server uses an https address. Does this mean that the JSON I'm sending to the server is automatically encrypted? What about when the server sends JSON back to the client?
If the link the JSON request goes to starts with https then yes. JSON is just content sent over http/https and responses are sent over the same method as the query.
However, if you are on a webpage and there is an ajax call made in the background, then maybe not.
In all cases, it depends on where the http get request goes to: if it starts with https then you are fine.
It sounds like your saying the request for json data is made over https, in wich case you are fine.
