For getting started with Android development:
- First you need the JDK.
- Next you need Eclipse.
- To make programming and debugging easy, Android provides an Eclipse plugin called Android Development Tools (ADT).
- How to Install ADT
- Start Eclipse, then select Help > Install New Software....
- Click Add, in the top-right corner.
- In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location: https://dl-ssl.google.com/android/eclipse/
- Click OK
- In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
- In the next window, you'll see a list of the tools to be downloaded. Click Next.
- Read and accept the license agreements, then click Finish.
- When the installation completes, restart Eclipse.
- How to Configure ADT
- Download the Android SDK and extract it.
- Start Eclipse.
- Select Window > Preferences
- Select Android from the left panel.
- For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory.
- Click Apply, then OK.
- Add Platforms and other components.
- Select Window > Android SDK and AVD Manager
Double-click the SDK Manager.exe file at the root of the Android SDK directory.
- Select the components you required and say Install.
( SDK Tool, SDK Platform tools and SDK Platform are the basic ones.)
Here we are done with it; now you can start with the development.
