How to install Android Development Tools (ADT)

1) Run Eclipse

2) Select Help > Install New Software.

3) Enter and hit Enter.

4) You'll see the Developer Tools item and you need to expand it to see its content (e.g. Android Development Tools, Android DDMS, Android Hierarchy View, Android Traceview). 

5) Select all items and click Next button twice.

Note: If you have any problems downloading the ADT, consult Google's help at

6) Accept the offered licenses - select "I accept the terms of the license agreements" and click Finish button.

7) Restart Eclipse after the installation is finished.

8) When Eclipse is restarted, you will be asked to configure your Android SDK. Because the Android SDK has already been downloaded earlier in the previous section, check the "Use existing SDKs" option and specify the directory where you have installed the Android SDK. 

9) Click Next. After this step, you will be asked to send your usage statistics to Google. Once you have selected your choice, click Finish.

Note: The installation steps could be slightly different in different SDK versions, so if you don't experience the same steps as we described, just follow the instructios on screen.
