MTP is the “Media Transfer Protocol” and is used by many mp3 players (e.g. Creative Zen) and mobile phones (e.g. Android 3+ devices). It is part of the “Windows Media” Framework and has close relationship with Windows Media Player.

Installation

MTP support is provided by libmtp, installable with the libmtp package from the official repositories.

Usage

After installation, you have several MTP tools available. Upon connecting your MTP device, you use:

# mtp-detect

to see if your MTP device is detected.

To connect to your MTP device, you use:

# mtp-connect

If connection is successful, you will be given several switch options in conjunction with mtp-connect to access data on the device.

There are also several stand alone commands you can use to access your MTP device such as,

 mtp-albumart        mtp-emptyfolders    mtp-getplaylist     mtp-reset           mtp-trexist
 mtp-albums          mtp-files           mtp-hotplug         mtp-sendfile
 mtp-connect         mtp-folders         mtp-newfolder       mtp-sendtr
 mtp-delfile         mtp-format          mtp-newplaylist     mtp-thumb
 mtp-detect          mtp-getfile         mtp-playlists       mtp-tracks

Using media players

You can also use your MTP device in music players such as Amarok. To do this you may have to edit /etc/udev/rules.d/51-android.rules (the MTP device used in the following example is a Galaxy Nexus): To do this run:

$ lsusb

and look for your device, it will be something like:

Bus 003 Device 011: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-P7500 [Galaxy Tab 10.1]

in which case the entry would be:

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0666", OWNER="[username]"

Then, reload udev rules:

# udevadm control --reload

mtpfs

Mtpfs is FUSE filesystem that supports reading and writing from any MTP device. Basically it allows you to mount your device as an external drive.

Mtpfs can be installed with the packge mtpfs, available from the official repositories.

• First edit your /etc/fuse.conf and uncomment the following line:

user_allow_other

• To mount your device

$ mtpfs -o allow_other /media/YOURMOUNTPOINT

• To unmount your device

$ fusermount -u /media/YOURMOUNTPOINT

• To unmount your device as root

# umount /media/YOURMOUNTPOINT

Also, you can put them into your ~/.bashrc:

alias android-connect="mtpfs -o allow_other /media/YOURMOUNTPOINT"
alias android-disconnect="fusermount -u /media/YOURMOUNTPOINT"

Or, with sudo

alias android-disconnect="sudo umount -u /media/YOURMOUNTPOINT"

jmtpfs

jmtpfs is a FUSE and libmtp based filesystem for accessing MTP (Media Transfer Protocol) devices. It was specifically designed for exchanging files between Linux systems and newer Android devices that support MTP but not USB Mass Storage. jmtpfs is available as jmtpfs in the AUR.

Use these commands to mount and unmount your device :

$ jmtpfs ~/mtp

$ fusermount -u ~/mtp

go-mtpfs

If the above instructions don’t show any positive results one should try go-mtpfs-git from the AUR. The following has been tested on a Samsung Galaxy Nexus GSM, Asus/Google Nexus 7 (2012 1st gen model) and Samsung Galaxy S 3 mini. (This is the only mtp software which worked for me on nexus 4. Settings are usb debugging enabled, connected as media device.)

If you want do it simpler, install go, libmtp and git from the official repositories. After that install go-mtpfs-git from the AUR.
As in the section above install android-udev which will provide you with “/usr/lib/udev/rules.d/51-android.rules” edit it to apply to your vendorID and productID, which you can see after running mtp-detect. To the end of the line add with a comma OWNER=”yourusername”. Save the file.

• Add yourself to the “fuse” group:

gpasswd -a [user] fuse

• If the group “fuse” doesn’t exist create it with:

groupadd fuse

Logout or reboot to apply these changes.

• To create a mount point called “Android” issue the following commands:

mkdir Android

• To mount your phone use:

go-mtpfs Android

• To unmount your phone:

fusermount -u Android

You can create a .bashrc alias as in the example above for easier use.

gvfs-mtp

Philip Langdale is has implemented native MTP support for gvfs. The weaknesses of gphoto2 and mtpfs are listed in his blog post.

• The native mtp implementation for gvfs has been merged upstream and has been released in gvfs 1.15.2.
• You can grab the stable gvfs-mtp package from extra. You may want to reboot your PC to make it actually working.

• Devices will have gvfs paths like this

gvfs-ls mtp://[usb:002,013]/

simple-mtpfs

This is another FUSE filesystem for MTP devices. You may find this to be more reliable than mtpfs. simple-mtpfs is available in the AUR or can be built from source. Remember do not run the following commands as root.

• To list MTP devices run

 simple-mtpfs --list-devices

• To mount a MTP devices (in this example device 0) run

simple-mtpfs /path/to/your/mount/point

• To un mount run

 fusermount -u /path/to/your/mount/point

KDE MTP KIO Slave

There is a MTP KIO Slave built upon libmtp availiable as package kio-mtp.

Using KIO makes file access in KDE seamless, in principle any KDE application would be able read/write files on the device.

Usage

The device will be available under the path mtp:/

Workaround if the KDE device actions doesn’t work

If you are not able to use the action “Open with File Manager”, you may work around this problem by editing the file /usr/share/apps/solid/actions/solid_mtp.desktop

Change the line

Exec=kioclient exec mtp:udi=%i/

To

Exec=dolphin "mtp:/"

GNOME gMTP

gMTP is a native Gnome application used for MTP access.

gmtp is currently located in the AUR .

Workarounds for Android

• HTC Phones automatically enter usb debugging mode on usb connect. Manually turn it off once connected to give libmtp access to the device.

MTP is still buggy and may crash despite the best efforts of developers. The following are alternatives:

• AirDroid – an Android app to access files via your web browser.
• FTP client on Android – If you run a local FTP server on Arch (such as Vsftp), there are many FTP clients available on the Play Store which will give read/ write access to your device’s files.
• FTP Server on Android. Note: since FTP client using passive transfer (server connect to client) do not forget to disable firewall or adding rules for allowing FTP server connect to your PC.
  • Ftp Server (by The Olive Tree) app in Play Store acts as FTP server on Android and allows RW access to pretty much all your storage.
    • Pro: Doesn’t require root and just works!
    • Cons: Doesn’t work with tethering network.
  • FTPServer (by Andreas Liebig) – Just work.
• SSH server on Android.
  • For example, SSHelper, available on the Play Store, just works without requiring root access. Assuming SSHelper is listening on port 20 and the phone’s IP address is 192.168.0.20, the following command will synchronise a local directory with the external SD card of the Android device:

 rsync --rsh="ssh -p 20" --modify-window=1  ~/local_files  192.168.0.20:/mnt/extSdCard/remote_files

Note the --modify-window option, which is often used when rsyncing to a FAT filesystem (such as the one used by Android devices for their internal memory and external SD cards).

• Samba – an Android app to share your SD card as a windows fileshare. Pros: Your desktop apps work as before (since the SD card appears as a windows fileshare). Cons: you need to root your phone.
• adb – Part of the Android development kit is adb android debug bridge. It can be used to push and pull files from an Android device.
  • The device need USB debbuging to be active and later connected to the computer with usb.
  • To send a file to the device use adb push /what-to-copy /where-to-place-it
  • To receive a file adb pull /what-you-want-to-copy /where-you-want-it
    • Pro: Stable, can be used for a lot more then just copy files back and forth.
    • Cons: Can be somewhat slow.

Security features on android

If you use android 4.x please unlock phone (screen unlock) and then connect phone to USB.

If you not unlock you have in KDE “No Storages found. Maybe you need to unlock your device?” or error 02fe in console.

1.将MTP设备连接至PC机

2.如果是第一次使用MTP设备需要安装以下软件，否则可以跳过此步骤：

$ sudo apt-get install mtpfs libfuse-dev libmad0-dev

建立挂载点

$ sudo mkdir /media/mtp

修改权限

$ sudo chmod 775 /media/mtp

3.挂载MTP设备

$ sudo mtpfs -o allow_other /media/mtp

如果提示设备忙，可以等一会再挂载。

4.传输文件（这时候以MTP模式进行传输），方法同USB，如：

$ cp video.mp4 /media/mtp/Movies/

5.卸载设备

$ sudo umount /media/mtp

我在Ubuntu 10.10上用Android 3.0做MTP设备是可以成功挂载的，挂载后会出现mtp的盘。

貌似不能用USB挂载，连上电脑后没有反应，sudo fdisk -l 也看不到东西

Ubuntu MTP ppa

Like I was telling you a while back, Gvfs has been updated in Ubuntu 13.04 Raring Ringtail, bringing a new MTP backend which allows users to access Android 4.0 devices which do not support the USB Mass Storage protocol, along with many other changes. Since it’s unlikely for the latest Gvfs (1.15.2) to be backported to older Ubuntu releases, you can use a PPA which has the latest Gvfs MTP backend backported to Ubuntu 12.04 and 12.10.

Upgrade Gvfs in Ubuntu 12.10 and 12.04 to get Android 4.0 support for devices which don’t support USB Mass Storage interface

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update

sudo ppa-purge ppa:langdalepl/gvfs-mtp 

二、安装busybox

把busybox安装到Android系统中去，做这几步：

1、在Android系统根目录下创建一个/bin目录。

mkdir /<path-to-Android-fs>/bin

2、把编译出来的busybox复制到/bin目录下

cp busybox /<path-to-Android-fs>/bin

3、把busybox安装到Android机器中

cd /bin

./busybox –install

三、把busybox作为默认shell

需要像下面这样编辑一下init.rc

1、编辑console服务，让它默认运行busybox

service console /system/bin/sh  ->  service console /bin/sh

2、把busybox路径加入到环境变量中

export PATH /sbin:/system/sbin:/system/bin:/system/xbin  –>  export PATH /bin:/sbin:/system/sbin:/system/bin:/system/xbin

注：

我使用busybox时，只是想简单地增加一些命令，把toolbox一些功能不是很全的命令替换掉，所以操作上没有上面说的那么复杂。下面是我的替代方案，可以试一下：

1、把busybox复制到/system/bin目录下。

adb push busybox /system/bin

2、把要添加的命令通过ln建立到busybox的连接。

比如，Android自带的toolbox是没有test这个命令的。我们要添加test命令就可以：

cd /system/bin

ln -s busybox test

这样，用户通过机器上的shell执行test命令时，就会调用busybox中实现test功能的applet。

对于一些原有的命令，如ls、chown等，如果不想用toolbox，也可以把它们的连接目标指向toolbox，拿chown来举例。

cd /system/bin

rm chown

ln -s busybox chown

这样做，最大的好处就是保证对系统的改动最少，又可以最大限度的扩展shell功能。
