I got a problem the file manager do not have remove file when the USB storage unmount.
When USB connected, ES File Explorer shows the USB device files under the path /mnt/media_rw/udisk on the imx6-sabresd demo image of android_L5.1.1_2.1.0-ga and then the USB removed the files still listed under /mnt/media_rw/udisk. I need press the refresh button of ES File Explorer to remove the USB device files. Android 5.0.0 Lollipop is also can not auto refresh file list when USB device removed. On the demo image android4.2.2 the file list or removed immediately at /mnt/media_rw/udisk when usb connect or remove. Other mobile phone can auto refresh USB device file instantly on android 5.0.0.
any suggestions are very welcome!
