Android SDK not found error
问题 I was working on an Android Project that uses Facebook SDK. Everything was fine until today. When I tried to run the project it gives the following error. Unable to resolve target 'android-10' until the SDK is loaded Although I have SDK 2.3.3 (Level 10), it doesn't appear in the project properties. In properties of Eclipse it says, This Android SDK requires Android Developer Toolkit version 21.1.0 or above. Current version is 21.0.0.2012-10-31-0-17. Please update ADT to the latest version.
