[Android Studio ERROR]Unable to start the daemon process

毫无征兆的出现此错误：

Error:Unable to start the daemon process. 

This problem might be caused by incorrect configuration of the daemon. 

For example, an unrecognized jvm option is used. 

Please refer to the user guide chapter on the daemon at http://gradle.org/docs/1.10/userguide/gradle_daemon.html 
Please read below process output to find out more:
