Uniquely connect an android application to a java applet on pc

Question

I want to connect my android application to an applet which is running on my pc on Google chrome on Wi-fi.. where my phone works as a wi-fi hotspot and pc as the connected device. I want the connection to work uniquely as I want commands to be passed from my application to the specific applet, on the execution of which my applet does specific tasks. Please tell me the APIs which I can look in both Java and Android or the technology I have to use to make it work..

Answer 1

You need to use any program, such as wamp server, to make your computer to be a localserver. It will install PHP 5, MySQL and Apache. In other hand, you will also need a little bit of knowledge in Php language to create you own web services.

Another thing you need to be aware is that to handle you connection between server and device (and by this I mean which IP you are going to use) you will have a little headache; but first things first..break your problem in little parts thus will be easier to solve them.

I recommend this tutorial.

Answer 2

I think the simple way to connect these two softwares is using UDP. It is fast, it is easy to program but it is generally unreliable according to TCP. But it is already local network. I dont think that is a case you need to take care in your local wifi network.

So take a look at this tutorial http://tutorials.jenkov.com/java-networking/udp-datagram-sockets.html

There are other ways like https://www.alljoyn.org/ . It has more functinality but more complicated.

Answer 3

You must install Server on your PC(Apache httpd or apache tomcat or other based on your interest). A server listens to request from clients. When your mobile is connected to your pc(doesn't matter wire or wireless), you can make a request to an url(say, localhost:8080/welcome) from your app.

Create an applet and connect it with your web application(in the server) using java.net.URL and java.net.URLConnection.

On performing some operation on the client, call the url of the server application and forward the response to the applet.
