Eclipse Android Installation Requires org.eclipse.gef

Eclipse Android Installation Requires org.eclipse.gef

在Eclipse裡安裝Android SDK時，因需要org.eclipse.gef而失敗。

Download and install the following packages from Eclipse web site:

1. Eclipse Modeling Framework (EMF, XSD InfoSet, SDO)
   Name: EMF
   URL: http://download.eclipse.org/modeling/emf/updates/releases/
   
2. Graphical Editing Framework
   Name: GEF SDK
   URL: http://download.eclipse.org/tools/gef/updates/releases/
   
3. Data Tools Platform
   Name: DTP
   URL: http://download.eclipse.org/datatools/updates
   
4. Web App Developers
   Name: Web Tools Platform (WTP)
   URL: http://download.eclipse.org/webtools/updates/
   

Problem: After selecting a site and no package shows up.
My Solution: Exit Eclipse, and start again. ie. clicking [Yes] to restart Eclipse did not work for me.

Stupid Mistake Made:
Once during the installation, at the page for agreeing the licence agreement, I tried many ways to get the greyed out [Next] button to reactivate. It turned out that it will never be activated. The button activated, by selecting the agreeing radio button, was [Finish]
Duh!

Install Android SDK:

1. Download Android SDK from: http://developer.android.com/sdk/index.html
   
2. Expand the package into a directory
   
3. From Eclipse, [Window]->[Preferences]->[Android], browse to and select the directory containing Android SDK.
