Hello I have an Arduino UNO connected to its LCD display. I programmed it to display any text you want by sending serial text to it. I have been Google Searching ways to do this but I haven't seemed to find a way for sending serial in java.
I am looking for an API or someway to possibly send serial text to my Arduino via USB. I chose java because I am more familiar with it.
Try RXTX Java library, it's a java serial communication library and works great with Arduino. Also the official Arduino website provides an example for Java-Arduino communication with help of this library, see here.

I'm interested to create android application that have all the functionality of PC mouse,keyboard and it can control the connected PC via wifi but I have little knowledge about this and I don't know where to start.I like to know are there are any protocol to do this,are there are any open source code project that i can download?
You should understand that this is not just Android application.
This is a pair of applications:
Computer - server
Android - client
And you get to decide how they will communicate. You can write your server application on C++, which will receive data via BlueTooth with Android and call the system API.

I'm trying to build an Android application which runs a service.
The service needs to pass certain device information to a custom server and receive some from the server.
Currently I've chosen a simple socket programming and JSON objects to implement this.
Can anyone suggest a suitable library for implementing this communication?
I'm a newbie and foresee a number of complications in implementing this.

I am looking for a Java Library that supports Bluetooth LE connections, specifically GATT and if I am lucky Apple's new iBeacon Protocol. It needs to be able to broadcast itself and if possible be able to initiate a connection.
I have seen BlueCove and even gave a shot at extending it to support Bluetooth LE, but could not get it to work. Does anybody know of any supported Bluetooth Libraries that work with Java SE, not for Android or Java ME, because that seems to be all I can find.
Any Ideas?

I need a Java API that i can use to receive and send SMS messages. I already know of SMSLIB, but am wondering if there is a better one out there.
What I found are the following links. They are simple sample code and only for sms receive and send from GSM modem via com port. Easy to modify and use them in own program. They are not like SMSLib(so many features but need a few third parties library and complex to use(at least for me)).

I want to make an application that can send an SMS to person in another country.
I have heard that using an international SMS gateway is the best way to do it, and is cheap (possibly even free).
What is the best library for achieving this?
There are a couple of options:
1) Use a java library such as smslib, which allows direct communication with a mobile phone modem to send or receive messages.
2) Register with one of the SMS gateway providers such as Clickatell or csoft and use their supplied apis. I would start by looking at the HTTP api here and here.
