*** REQUIRES ROOT ACCESS ***

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).

安卓4.4奇巧删除您来写文件到MicroSD卡（上有内部存储器和用户安装MicroSD卡手机/平板电脑）的能力。 NextApp SDFix通过修改配置文件恢复这种能力。由于这个程序修改系统配置文件，它需要root权限。

警告！安装之前请参阅：

---------------------------------------

*此应用程序需要root权限。如果您不知道这意味着什么，请不要安装该应用程序。

*这个程序是用来改变设备配置文件。

*请完整阅读本应用程序清单为正是这个应用程序，以确定它是否是适合您的设备和/或定制ROM的说明。

*这个程序是专为解决特定问题。如果你没有这方面的问题，请不要安装这个程序。

*这个程序是唯一有用的是有一个用户安装的MicroSD卡的设备。如果你有一个谷歌的Nexus设备或其他设备没有，你实际安装自己一个MicroSD卡，那么这个程序是不会有帮助的。

*这个程序是有可能唯一有用的，如果你有一只股票的ROM。如果你正在运行一个售后的ROM像CyanogenMod的，那么有没有理由要安装此应用程序（好售后ROM不从这个程序纠正该问题的影响）。

*不保证：作为一般是与所有根的修改的情况下，假设你使用该软件的所有风险。

*对于任何根修改，确保你拥有的知识您的设备完全恢复到股票，如果需要的。

[关于microSD卡中的Andr​​oid 4.4 /奇巧]

当谷歌发布Android 4.4，他们指定的应用程序下载不能再写入到用户安装的MicroSD卡。应用程序仍然可以写入内部闪存存储。某些设备（如谷歌的Nexus设备）只有内部存储，并不会受到影响。其他设备（如三星Galaxy和注意事项设备）必须通过安装MicroSD卡拓展存储空间的能力。当安装在这些设备上奇巧，应用仅限于能够操纵的内置存储文件，具有写访问被限制的MicroSD卡。

这种变化代表了去除功能与Android 4.3相比。 4.3允许应用程序写入MicroSD卡，就像以前的版本。

在奇巧引入的限制不影响预装的应用程序的能力，只有应用程序，你选择安装。预装的应用程序由谷歌，你的设备制造商和运营商仍然有这个能力。只是你自己选择要安装的应用程序受到限制。

[技术详情]

NextApp SDFix将修改位于/系统/ etc /权限/ platform.xml允许应用程序写入到MicroSD卡中的配置文件。具体来说，SDFix将增加Android的UNIX组“media_rw”到WRITE_EXTERNAL_STORAG​​E权限的配置。这将使应用程序（仅适用于您授予写访问权限，当你安装这些那些）写入文件到MicroSD卡。在许多设备上，这是有效地恢复此权限的状态恢复到它被配置在安卓4.3的方式。这种修改是通过修改现有的XML文件，而不是取代它。

原来的配置文件的备份将被保存在/系统/ etc /权限/ platform.xml.original-预sdfix（提供一个不存在的话）。回复此修改可以通过使用一个根功能的文件管理器来替换/系统的/ etc与备份版本/权限/ platform.xml文件来完成。
