Running MX Player on a Nexus 10 to access an ext4 USB Flash drive How would I play an MP4 on a USB Flash drive connected to the Nexus 10?  The drive was formatted with Ubuntu with ext4 format.  I have the MX Player but it does not see the USB Flash drive.
Usually Android can use only FAT32 because of permissions in ext file systems. If you have a terminal emulator installed + root + busybox you can do it like that:


Open terminal;
Type su to get root;
Insert cable and flash drive;
Type dmesg to get device name;
Make a folder using your file manager;
Try to: mount -t ext4 /dev/(device name) (path to folder you make);
Enter the folder: cd (path to folder);
Change the file permissons: chmod 777 (your file);
Go to that folder with file manager and play.


Or you could just use StickMount.
