Abstract
The invention discloses a method for stopping a media scanner after USB device ejection in an Android system. The method includes the steps of receiving the ejected media of a USB device to obtain a USB device path; assigning the USB device path from the ejected media of the USB device to a system attribute of the USB device path; acquiring the system attribute of the USB device path to obtain the USB device path; judging whether the path of a to-be-scanned file includes the USB device path obtained from the system attribute of the USB device path, if yes, skipping the to-be-scanned file to save the scanning step. The invention also discloses a system for stopping the media scanner after USB device ejection in the Android system. After the USB device ejection, the scanning of the USB device media file is automatically stopped, the USB device can be unmounted from the Android system successfully.
Description
Technical field
Embodiments of the invention relate to Android system, more particularly, to extracting USB in Android system
Media Survey is stopped after stopping after equipment the method for Media Survey and Android system are extracted USB device
System.
Background technology
The popularity rate of the smart machine of currently used Android system is more and more higher, on these smart machines
Application USB device is more universal, such as, access USB portable hard drive in intelligent television, broadcast
Put the video of storage in USB portable hard drive, check photo of storage etc. in USB portable hard drive.
But Android system there is also deficiency in terms of USB device process: when user inserts USB device (example
Such as USB flash disk, USB portable hard drive etc.) time, Android system can send broadcast notice has new equipment to access,
One system application of Android can receive this broadcast, proceeds by Media Survey (Media Scanner)
Go to scan the media file (such as music, video, picture etc.) in USB device, obtain USB
The information such as video in equipment, music, picture also store in database, use for other application.
After user extracts USB device, Android system can perform unloading order (unmount), only unloads
Carrying order to run succeeded, Android system just will be considered that real being removed of USB device.If used
Family is extracted after inserting USB device the most in a short period of time, if the matchmaker of storage in this USB device
Body file is too much, it is more likely that during Android system is also in Media Survey, Media Survey program
Taking this USB device, this can cause USB device unloading (unmount) failure, even can
Causing system to occur can not the consequence (Application Not Responding) of response application.
