Hai,

I checked the links,when i try to compile always iam getting error like

1. setContentView(R.layout.date_widgets_example_1);

Error in R cannot be resolved.

It cannot able to recognise the R.java if iam not wrong.

The same problem iam getting in all the samples.

2 .About the classes link i went thru it,but can you please let me know what are the classes we will be refering mainly.

3. String destinationAddress="192.168.1.103 "; sm.sendTextMessage(destinationAddress, null, "Hello world", null, null, null);

This example i got from the samples for SMS ,but i dont know what i have to give the destinationaddress,i tried by giving my system ip address.But i cannot simulate in the Simulator.What else i have to add?

Can you let me know what may be the mistake i have done Thanks in Advance.

Regards, Lavanya S.R

Iam new to Android ,i have worked in Java and in Eclipse IDE,so i downloaded some examples and started doing it.Iam having doubt in the below mentioned,if some one helps me in resolving i will be pleased to them..

1.What is the real need and usage of Android?

It's an operating system for mobile phones.  See

   http://code.google.com/android/

 2. How the Simulator and our application interacts?

Your application runs in the simulator.

3.Can you suggest me a link where i can view all the classes used in this SDK?

Did you try just looking around the website?

   http://code.google.com/android/reference/classes.html

4.What are the Features supported by this?

See:

   http://code.google.com/android/what-is-android.html

5. To develop an application for sending an SMS what are the classes we have to see?

Again, if you just look around the documentation, you can answer this yourself.  It took me about 5 seconds to find android.telephony.gsm.SmsManager.

Maybe you wanted some more specific information; asking a more specific question might help.
