I have an android phone that runs on ics. I have a desktop application written in java which runs on desktop system.
Can I run independent java program on it?
Thanks
No, you can't run a java application written for desktop directly on Android. Android has a heavily modified java runtime environment.
But rewriting your application for Android shouldn't be too much of a pain, as you just have to convert your UI to Android widgets(called "View") and to adapt your code to Android [Activities](http://developer.android.com/guide/components/activities.html).

I'm in 2nd year of bachelor and working on my final project which is on the end of 3rd year.. But the project is on Java. I want to make it run in my laptop and on my phone. But I have a Microsoft Lumia 640. And I know how to create apps for my phone just in C#. Is it possible to design a mini software, and run it inside a C# app in my phone?
No, natively Windows Phone doesn't support Java but you can take a look to codename one where in their manifesto says that you will able to make mobile application for any platform only using java.
If you habe the java application as a jar lib you can use ikvm (a jvm for .net) and then you can theoretically run java bin code on the windows phone... you will need to take a look because maybe the issue will be how to deploy that jar to your phone at runtime
Is it possible to run "python" script inside "Java" in an android app?
The main app will be Java but some cryptography should be done in "python"
Is it possible to do this?
Running a python script inside android app is not practical at the moment, but what you can do is creating a HTTP web service for interpreting python and sending back the results to the android application.
Then it's just Android app communicating with a HTTP web service which is simpler than packing an interpreter.
This way it makes the app lighter too.
I'm planning to write a software (with GUI and sounds) that should run under Android and Windows 7/8
I guess the best approach for this is to use Java?
I am new to Android and Java development so my questions are:
-So can I use one development platform to create both (APK & JAR), namely Java?
-As far as I understand for Android I need to compile (from same source?) a .APK file and for Windows a .JAR file ?
(The .JAR will run in the Java Runtime that is installed in Windows)
-If I use Java what would be the best IDE, something like Google's Android Studio (will it allow to create .JAR?) or Oracle's JDK (Java SE Development Kit) ?
thank you
I don't think it is possible to write an app that will run on both OS's, since all GUI components are part of different frameworks (Android SDK for Android, SWT/Swing/... on Windows), and not compatible with all OS's.
You best bet is probably a web-based app. You can run it in the browser on dektop and either on a mobile browser on Android, or package it as a fullscreen WebView running your web app. The best part is it would also work on iOS.
You could also write your app for desktop in Swing and then convert it to an Android app, you can find questions on StackOverflow on the subject, such as this one.
Hope this helps ;)
I have learnt android application programming. My command is with java.
Some sites provides their sdk for multi platform development, but i am not getting them
Xamarin can develop androids app using c#. Is reverse possible?
Can i develop windows app using java? If yes how?
Yes, you can. Codename One is an SDK that will allow you to create Android, iOS, RIM, and Windows mobile apps all by using native Java.

yes you can develop windows app using java , actually the main point of java is that you can run it on multiple platform (write-once-run-everywhere) ,i can't get what you mean with how, you build jar file from your app so you can run it everywhere that has jdk or jre
and about android , yes you can write it using c# ,i hope this link will be helpfull.
I recently installed the Bluestacks Android emulator. I happened to look at the process running under ProcessExplorer and was surprised to see that it is a .NET application.
The HD-Frontend.exe is the Bluestacks UI process and is highlighted yellow because it has loaded the .NET framework. There are a number of other processes associated with Bluestacks and most are also .NET.
Opening the EXE in Reflector.NET also shows that it is .NET.
I thought Android was Java-based. What's going on here?
Android is Java-based, but that does not mean an Android emulator has to be written in Java -- just functionally emulate Android devices.
While BlueStack's site does not list any system requirements for its emulator that I could find, at least a couple sites -- e.g. Bazooka Apps and Android Emulator for PC -- mention .NET as a requirement.
Ultimately the proof of what's going on is right in the process list and Reflector results you found.
its an emulation tool whose job is to read the dex code respond to that how the android phone should respond and not to compile and run that dex so it could be on python or ruby also there is no boundation at all that you have to make android emulator on java becuase android is built upon java.
