I have an android application APK that has been burnt in the android OS. So it becomes its native application. So can you please guide me how I remove it after OS burnt on the phone. If I cant remove it without root access. Can I update this native application by any way. It is not uploaded on Google Play. So can I do this that I can upload its newer version on Google Play Store and then update manually from device android market/play store application?
Please guide me if this option is valid or not. If yes then How? And If No then how can I achieve this.
Thanks in Advance...

been burnt in the android OS
No. It's only installed on (by default) read-only partition.
So can you please guide me how I remove it after OS burnt on the phone
You need write access to that partition => root
Can I update this native application by any way
Yes. Just install any new app with the same package id and singed with the same certificate the ROM-installed version is and you got it updated

UPDATE: Todays time android automatic suggest and check marked the required packages.
I am so much confuse about installing Android SDK packages. What packages should I install from this long list. I am beginner student and it not make any sense to me what things does what.
I need a minimalistic setup for very basic or beginner level app development.
what the best installation for eclipse (minimum packages).
Give me best idea for this install packages.
If you are planning to develop for API 15 and above, then just download API 15-23 to get the minimum download as well as maximum tools. API 15 is what I use as it takes up 90+% of the Android market, and is a good choice.
I would recommend you download all the Extras, especially the HAXM if you are planning to use the Android emulator to develop instead of testing your app on a real device.
For the Tools/Build-Tools/Platform-Tools, I suggest only downloading the latest version, and if you are planning to save space, delete it and download the next latest version which can be seen in the Rev. column. As a beginner, I recommend you don't try out the Tools(Preview Channel) as they can still contain glitches or are unstable as they are still in alpha.

In Eclipse, I have an android app and a Java Swing application that I run. If they are both running from Eclipse, can I get access to the other and read objects from it? This functionality is for development only and will not be used outside of eclipse.
I am aware of socketing in Java, but I would like to be able to read and modify variables on objects in runtime if possible.
Alternativelly, one could devise such a thing.
The Java app would need to be redesigned a bit, in a server-y way, to accept incoming pseudo-connections from a library.
The library which would expose the Android internals would have access to Android app via JNI. The said library would be compiled as a .SO file and included in the android app.
That being said, you would need to develop the said library to act as a bridge between your Java app, and your Android app.
if your only pourpouse is setting variable values on runtime just for development, the best option may be debug the app, and set breakpoints where you need to stop, set desired values and go on with the debug proccess
No, you cannot read objects from your Android App with your Java app.
Why? Android runs in emulator, which is a whole different process than the one running your Java code. Lately, OSes tend to not let any process touch other processess's memory because, well, malware.
The only way your Java app could touch Android app is if it were the parent of the Android app's process. Which is not going to happen. (unless you make it so)
So you need to redesign both of your apps with that feature in mind, and use the Java app as a backend that your android app will communicate to all the time, and think of your Java backend as "the server" - meaning, what the server tells you to do, you do it no questions asked.
No, you may not also 'poke' values at runtime without a attached debugger.

So I got this idea that I want to implement as an Android application. Now what I have learned so far is Java, C and C++. As I understand, Java would be the smartest choice right? Have to mention tough, my experience is of a 1st year CS student's.
So I basically want to make a application that you can launch from the phone and it will also have a little database and fetch info into it from the users Facebook account.
So my questions are these:
The facebook part seems to be the hardest one to me. How is this done? Are there any articles around where I could read about it.
Second is, should I develop the application in Java?
And third one is... If I do it in Java, I see that Google has a lot of stuff up for learning all of it. It also features two development kits. One is a stable version which works with eclipse and the other one is a preview thing which is a 0.xx version.
The second one seems to have all thoes fancy thing tough like having the phone preview on the screen all the time so that you can see how it looks like on the phone. And it seems to me that the Eclipse version does not have such features. So which one would be smarter to pick?
Today, most apps for android are written in Java and with Eclipse. I would recommend you to do the same, because it is the easiest way at the moment (IMHO).
The Android Studio is still in the alpha state (as you said), so it can have some bugs. That's why you should use Eclipse (Android Studio looks great though).

Edit for "how apps looks like in eclipse":
You have 3 options in eclipse to get a view of your app:
1. The xml-layout builder: in Android, you can create the layout of the app via xml or code. In Eclipse you have a preview of your applayout which you designed in xml (How it looks like)
2. Upload the app on your phone and watch it
3. Upload it on an android-emulator, so you don't have to use a phone

Is it possible to update my google app engine java application without dropping user traffic?
AppEngine deploy procedure doesn't put your site nor your data in offline/read only mode. As far as the deploy is implemented your user won't notice any issues (as long as your new code didn't introduced any)
yes u can ..
gae projects allows multiple versions for the same project ,you can have upto 8versions i think ..
say ur application name is abc.com
u can deploy ur project to another version like 2.abc.com
and when ur okay with the version 2.abc.com
you can change that to default in GAE .
Now refering to abc.com will actually refer to 2.abc.com this will not affect any of ur traffic

I have a old LG MG280 cellphone that I'd like to code some simple things for. It has Java support, but I know that it is not simply making a Java ME application. It has to follow some specific specs otherwise the app will not run. Does anyone know what those specs are?
JavaME platforms are made up of a profile and a configuration. Most mobile phones use some combination of the Mobile Information Device Profile (MIDP) and the Connected Limited Device Configuration (CLDC).
The LG MG280 you are interested in uses MIDP-2.0 and CLDC-1.1, which is pretty standard.
To get started with development you'll probably want to be using the Sun Java Wireless Toolkit (frequently abbreviated to SJWT or WTK). Or, if you are a windows user, you can use the (newer) JavaME SDK 3.0. This gives you tools needed to compile/package applications and an emulator which lets you run/debug application on a desktop computer.
There are numerous tutorials available online. Here's a few to get you started:

http://developers.sun.com/mobility/midp/articles/wtoolkit/
http://developers.sun.com/mobility/learn/
http://www.developer.com/java/j2me/article.php/1561591
Find out which J2ME profile it has - MIDP etc. Then find an appropriate tutorial, such as this one.
