I am beginner.
Need help from where to start?
If you can provide some resource or tutorial then it will
very helpful for me.
Thanks
You can start from here
A tutorial from Lynda for beginner it very simple and easy.
You can take care of it
It named "Lynda.com - Android App Development with Java Essential Training"
Here you can learn how to download eclipse and how to set it up.
http://developer.android.com/sdk/index.html
Here you can learn you to code :D
http://developer.android.com/training/index.html
If I were you I'd also check out Android Studio alongside / instead of eclipse. It's beginning to become widely used in the industry and shouldn't be in preview too much longer :)
First you need to set up development environment
An easy way to set up:
http://developer.android.com/sdk/installing/bundle.html
Then try http://developer.android.com/training/basics/firstapp/index.html to have a feel how to program in android

I wanna create a simple chat app in android but really I don't how to start
I really searched in google but really I didn't find any helpful link or code
so guys please I need your help how Can I start any video link or any simple code
In case you have some experience in Java I can recommend this book:
Professional Android 4 Application Development (Wrox)
It really helped me to get started with Android development. Otherwise the best start is probably a quick introduction to Java. In German there's also a book called Java for Android, not sure if it exists in English, too.
Also for inspiration you can have a look at this:

Is it possible to adapt this java code from this webpage http://www.dreamincode.net/forums/topic/27950-steganography/ to be used on the android sdk.
It has ImageIO, WritableRaster and things from java.awt. If its possible please tell me how!
Thanks
Is it possible to adapt this java code from this webpage http://www.dreamincode.net/forums/topic/27950-steganography/ to be used on the android sdk.
Is steganography possible using the Android SDK? Yes. You would manipulate the byte[] of a Bitmap, either in Java code, in native code via the NDK, or perhaps using Renderscript Compute.
Can you perhaps leverage the steganographic algorithms from that code when you write your Android implementation? Presumably yes.
However, as you note, that code depends heavily upon classes that are not part of Android, which is why would you be better served starting with the algorithm and creating a native Android implementation from there, rather than trying to "adapt" the AWT-dependent Java code directly.
Or, see if somebody already has an Android steganography library that you can use.

How to make a share button in my image application so that when we press share button it share the current image to different option like whats app,facebook etc.Plz Answer That
See the tutorial in the Android docs on Adding an Easy Share Action. It tells you exactly what you are asking.
That tutorial uses a ShareActionProvider, which is only since API 14. To support earlier versions of Android, take a look at the accepted answer in this thread. This third-party tutorial also provides lots of good info.

How can I implement an OCR function in my android app? I want to make an app that takes a picture and translates a text from it. Any APIS or tutorials for that?
Thanks
Update: Here some additional links I found that may assist you on configuring tesseract. I personally have not use this, as I personally opted for 2D code approach.
http://rmtheis.wordpress.com/2011/08/06/using-tesseract-tools-for-android-to-create-a-basic-ocr-app/
http://gaut.am/making-an-ocr-android-app-using-tesseract/
Original answer
Well without knowing anything about your app, I would like to note that you probably could not beat Google Googles when it comes to OCR features. Maybe you can add additional detail what kind of text do you want to be able to translate? So we know your not reinventing the wheel :)
I found a few links
https://code.google.com/p/tesseract-ocr/
http://ocrsdk.com/producttour/many-more/
But if I may suggest, if you it specific message that can you want to parse, I would recommend actually using QR barcode. You can convert a CSV file into 2D code and then have your app scan it then parse it to do some custom feature.
Here library I used for 2D code and found it quite useful in the past. Zxing which is open source and free to use

I need to customize the android.widget.Gallery. Where can I download the source code?
Here it is:
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.1_r2/android/widget/Gallery.java
I like GrepCode most because it's really convenience to browser Android source code online, as well as reference others class.
Here's the link to the latest version of the android.widget package:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/widget/
You can find the source to Gallery.java there. Of
course you can also check out the whole source code as well.
You can find it here
In linux or mac you may download the whole source. see here
You can find it here
Google Code Search is such an underused resource. Enjoy it.
You will likely need other files from the source code as well.
Also, make sure to document the changes you make or you will face a hell of a challenge when you want to update to a new version of the Gallery.
Here is the list of Git repos: https://android.googlesource.com
It's a good idea to check this guide out: http://source.android.com/source/downloading.html
And here is the actual class:
