【Android】Android Debug certificate expired

I just Run first Project then get a error: Debug Certificate expired on 2010/12/14 下午 2:13

• Q：After installation, the android SDK wil generate a "Debug" signing certificate in a keystore called debug.keystore. The Eclipse plug-in uses this certificate to sign each application build that is generated. But, a debug certicate is onle valid for 365 days. To generate a new one you must delete the existing debug.keystore file. Its location is platform dependent - you can find it in Preferences - Android - Build - Default debug keystore.

• A：Delete "C:\Users\userName\.android\debug.keystore", the system will generate a new debug certificate automatically.
