I am trying to building a LAN messenger application in android.
I searching on internet for reference project but while reading their code i am not able to understand what actually going on.
Can anyone help me or point me to some other good resources that can help me in my project will be great.
It is enough for me if some one told me key points(what are the things required for this kind of project) and just give me little push so that i can start.
An idea would be to use the open source Alljoyn framework to exchange messages on the LAN. There is also a chat example that you can download, run and examine.
More info here:

I have a rc drone. I want to create an Android app to control it but I do not know where to begin and how. I browsed the internet and found only one useful tutorial but it required use of Adruino and was through Bluetooth but I want to create my own Android app and not use Adruino or Raspberry Pi. Please help
First you need to connect via bluetooth (If you have no documentation of your RC drone it will be had to figure out the commands etc).
Maybe you can find a bluetooth sniffer program on the www to record what is going on when using the original hardware.
But I think its not worth the effort. To figure all this out will most likely take a lot of time and might not lead to success at all. So I recommend: next time by a drone where the communication protocol is documented or better a SDK is provided with it.
First, you have to figure out, if this drone uses Wifi or Bluetooth for control, or, some custom- build wireless device. If it use custom adapter, working on another frequency, you won't be able to do anything from software, only reverse- engineer control schematics.
I want to build a project of video chatting + messaging by java without internet connection through *lan*. But i can't get any idea about what to do and how to do? I am beginner in java GUI. So I want to know the topics that i have to learn and from where?
well, you will need to look up data streaming, showing video stream on panel and socket and protocol manipulation in the java docs and other online guides. those are the foundation you will need for the project. as for the GUI, it is not hard.. there are many tutorials out there.
if you face a problem we will help, but we will NOT do it for you... start something first.
examples:
GUI
Network basics
Video streaming
do your research... that is the way to learn
also, research steps of making (analyzing) a project
So I have received a task to develop a prototype software for testing the software/hardware component of android. Example: By using the software I can send a command from my PC to my android to change the color of screen display without interacting with the devices(touch,shake or other possible gestures). I would like to know how do I actually start. The whole idea is actually messed up in my mind. Because after a few days of research I haven't found any topic related to what I am going to do. I am still fresh with java so please go easy on me :) Any help is much appreciated.
hi this is very much feasible. First you need is a web service that connects your software to your phone. When you give command on your software, the command should go trigger the web service which in turn should send a push notification to the phone to execute your command. You will be needed to create a some sort of listener and push notification system on your phone(Hint GCM may work). Also you will need to add permissions to your app that is listening to the notifications. Does that make any sense to you?
I am trying to develop my Android application which would connect via bluetooth with PC computer and would be able to send data both ways. Like, sending string from Android application to PC and receiving the string on the screen and the other way aswell.
I am on my way to create the application on Android but I was wondering what would be the best way of resolving problem with PC: How would I send and receive the data? Firstly, I thought that I would need separate program but maybe there is some other way?
Could use ANY help on that subject.
There are a lot of solutions for this problem.
Here is the one of possible solutions which could you use as a start point (https://github.com/xamarin/monodroid-samples/tree/master/BluetoothChat).
Here is quick tutorial Simple Android and Java Bluetooth application (http://luugiathuy.com/2011/02/android-java-bluetooth/)
Hope that helps.
