摘要： Methods and apparatus are provided for managing an application error. Error record information on at least one application in which an error has occurred is collected from at least one portable device. The collected error record information is stored in a table that maps error information of each application. An application list provision request is received from a portable device. At least one application to be filtered from an application list is identified based on the error information of each application mapped in the table. The application is filtered from the application list to generate a filtered application list. The filtered application list is provided to the portable device.
