Android 4.4 KitKat removes your ability to write files to the MicroSD card (on phones/tablets that have both internal memory and user-installed MicroSD cards). NextApp SDFix restores this ability by modifying a configuration file. As this app changes a system configuration file, it requires root access.
WARNING! PLEASE READ BEFORE INSTALLING:
* THIS APP REQUIRES ROOT ACCESS. IF YOU DO NOT KNOW WHAT THIS MEANS, PLEASE DO NOT INSTALL THE APP.
* This app is used to change a device configuration file.
* Please read this entire app listing for a description of exactly what this app does to determine if it is appropriate for your device and/or custom ROM.
* This app is designed to solve a specific problem. If you don't have that problem, don't install this app.
* This app is only useful on devices that have a user-installed MicroSD card. If you have a Google Nexus device or other device without a MicroSD card that you physically installed yourself, then this app isn't going to be helpful.
* This app is likely only useful if you have a stock ROM. If you're running an aftermarket ROM like Cyanogenmod, then there is no reason to install this app (good aftermarket ROMs don't suffer from the problem that this app corrects).
* NO WARRANTY: as is generally the case with all root modifications, you assume all risk by using this software.
* As with any root modification, ensure you have the knowledge to fully restore your device to stock if required.
[ About MicroSD Cards in Android 4.4 / KitKat ]
When Google released Android 4.4, they specified that applications you download can no longer write to user-installed MicroSD cards. Apps can still write to internal flash storage. Some devices (like Google Nexus devices) only have internal storage, and are unaffected. Other devices (e.g. Samsung Galaxy and Note devices) have the ability to expand their storage space by installing a MicroSD card. When KitKat is installed on such devices, apps are limited to only being able to manipulate files on the built-in storage, with write-access to the MicroSD card being restricted.
This change represents a removal of functionality compared with Android 4.3. 4.3 allowed apps to write to the MicroSD card, as did prior versions.
The limitation introduced in KitKat does not affect the capabilities of preinstalled apps, only apps you choose to install. Apps preinstalled by Google, your device manufacturer, and your carrier still have this ability. Only apps that you choose to install are restricted.
[ Technical Details ]
NextApp SDFix will modify the configuration file located at /system/etc/permissions/platform.xml to allow apps to write to the MicroSD card. Specifically, SDFix will add the Android UNIX group "media_rw" to the WRITE_EXTERNAL_STORAGE permission's configuration. This will enable apps (only those that you granted write access permissions to when you installed them) to write files to the MicroSD card. On many devices, this is effectively reverting the state of this permission back to the way it was configured in Android 4.3. This modification is carried out by modifying the existing XML file, rather than replacing it.
A backup of the original configuration file will be saved at /system/etc/permissions/platform.xml.original-pre-sdfix (provided one does not already exist). Reverting this modification can be accomplished by using a root -enabled file manager to replace the /system/etc/permissions/platform.xml file with the backed up version.
[ Additional Information ]
This app is free and has no advertisements (with the exception of links to other NextApp apps when it completes its task).
--- Please do not contact me with requests for information on how to obtain root access on your device. The process is different for every device, and often requires technical expertise to install. ---
A complete and free SSHd, SFTP, SCP and Telnet server! From now on you can run a complete SSH daemon (server) with support for multiple users, public key authentication, and you can even set a directory per user for SFTP and SCP.
NO ROOT is required, but if you do have a rooted device you can run SSH as super user if you want. The shell will only work on ARM devices, however, the SFTP and SCP servers will work on all devices.
To run on ports below 1024 search for Android app Port Forwarder Ultimate.
Note 2. If you find a bug or have a problem please contact us by email since we cannot help you if you post it in the reviews.
In this version you can add one server (SSH, Telnet or Dynamic DNS Updaters), three users and three optional allowed IP addresses per server. If you want to be able to add unlimited items please buy SSH Server Pro. If you buy the pro version you will support development, will be able to add unlimited items and see no advertisements!
★★For more servers and features have a look at our app Servers Ultimate★★
And we haven’t mentioned all yet; you can even set a dynamic DNS updater!
It also has extensive logging functionality, and you can even set the app to email you the log automatically!
- SSH has support for SFTP and SCP
- For SSH, SFTP and SCP multiple users can be set with each their own root directory, password, public key (RSA or DSA), allow X11 or agent forwarding, allow inbound/outbound connections, optional write permission and optional force stay in root directory
- For Telnet you can add multiple users and run Telnet through SSL/TLS with your own certificate or our certificate
- Set your own shell start command and arguments (advanced)
- Start/Stop a server automatically when connected/disconnected from a specified WIFI network, or on boot
- Verbose log (filter, email, etc)
- Add a Dynamic DNS Updater using the local or public IP of your device
- The servers can be accessed from the web (for example through your 3G connection) if supported by your mobile network
- Add multiple SSH (SSHd, SSH daemon) or Telnet servers
- For every SSH Server you can set name, port, multiple users, only access from certain IP addresses, vibrate on a new connection, enable logging, only log errors, start the server when connected to a specific WIFI network and disconnect when the WIFI network is lost, start on boot, max auth attempts, authorization timeout, idle timeout, max concurrent sessions (per user)
- For every user set the username, password, public key, X11 / agent forwarding, inbound / outbound connections, document root, force stay in document root, allow write access
- For every Telnet server you can set multiple users or even enable SSL/TLS with your own certificate or our certificate
- Add multiple dynamic DNS updaters (set a custom URL, or choose from ChangeIP, DNSdynamic, DNSexit, DNSMadeEasy, DNS-O-Matic, DNSPark, DtDNS, DynDNS, easyDNS, eNom, HE.net, Joker, Namecheap, No-IP, ZoneEdit)
- For every dynamic DNS updater set the name, timeout (in minutes), hostname, username, password and whether to update with the local or public IP address, start the Dynamic DNS Updater when connected to a specific WIFI network, update on connectivity change, start on boot
- On the settings page of the app you can set the maximum log items to keep, whether to keep a WIFI lock (prevent WIFI from disconnecting automatically), keep the device alive, keep the device alive full (keep the screen on, battery intensive), set to start the app on boot
- You can search/filter the log, or set it to be automatically sent when the log limit is reached
