Eclipse Android project name有错误, source tree无红叉解决办法
linux:Window -> Preferences -> Android -> Build中Default debug keystore显示了地址“/home/xxx/.android/debug.keystore”,删除此路径下的debug.keystore 及 ddms.cfg
Window XP:进入:C:\Documents and Settings\Administrator\.android (Win7在C:\Users\xxx\.android)
删除:debug.keystore及 ddms.cfg
