Let Me Know Your Code

Activities? Intents? SimpleCursorAdapter? Huh? Hmm...how do I proceed?

you've downloaded the SDK and ar currently ready to make subsequent killer app for mobile (and presumably win some $$ within the methodology ;)

Well, that depends on your vogue. Some would require to rigorously undergo all the documentation top-to-bottom, whereas others might like better to dive right in to code.

Either path can finally result in the sample applications provided within the SDK � these samples are going to be valuable in your go after robot mastery. The samples include:

Source code and resources for these applications ar offered within the SDK (samples/) also as online: http://code.google.com/android/samples/

API Demos
A 'kitchen sink' application that covers the foremost helpful aspects and elements of the robot genus Apis. you will see totally different implementations of Activities, Services, Notifications, Layouts, also as ways for operating with graphics and text. This application provides a stunning supply of templates for your comes and a respect to 'How do I do this?'-type queries.
Lunar Lander
A game that demonstrates a way to load and draw graphics, animation techniques, taking user input, saving state once the user pauses the sport, and more. committal to writing mustn't be this fun!
Note Pad
you will find out how to create use of Intents to open a replacement screen, access an area information, and more. This sample could be a pretty introduction to application flow and life cycle management, that ar very important in developing a lot of complicated applications.

Here ar some suggestions on what to try to to next:

scan through every application's manifest file (AndroidManifest.xml) to find out regarding the standard structures in associate degree robot application.
Alter the code to acquaint yourself with the building and testing methodology.
Use a selected code piece as either a base templet or to urge some required practicality for your own project (why reinvent the wheel?)

Put these sample applications through their paces; and within the event you stand still, post your inquiries to the robot Developers Discussion cluster.
