*** 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).

***需要root訪問權限。***

安卓4.4奇巧刪除您來寫文件到MicroSD卡(上有內部存儲器和用戶安裝MicroSD卡手機/平板電腦)的能力。 NextApp SDFix通過修改配置文件恢復這種能力。由於這個程序修改系統配置文件,它需要root權限。

警告!安裝之前請參閱:
---------------------------------------
*此應用程序需要root權限。如果您不知道這意味著什麼,請不要安裝該應用程序。
*這個程序是用來改變設備配置文件。
*請完整閱讀本應用程序清單為正是這個應用程序,以確定它是否是適合您的設備和/或定制ROM的說明。
*這個程序是專為解決特定問題。如果你沒有這方面的問題,請不要安裝這個程序。
*這個程序是唯一有用的是有一個用戶安裝的MicroSD卡的設備。如果你有一個谷歌的Nexus設備或其他設備沒有,你實際​​安裝自己一個MicroSD卡,那麼這個程序是不會有幫助的。
*這個程序是有可能唯一有用的,如果你有一隻股票的ROM。如果你正在運行一個售後的​​ROM像CyanogenMod的,那麼有沒有理由要安裝此應用程序(好售後ROM不從這個程序糾正該問題的影響)。
*不保證:作為一般是與所有根的修改的情況下,假設你使用該軟件的所有風險。
*對於任何根修改,確保你擁有的知識您的設備完全恢復到股票,如果需要的。

[關於microSD卡中的Andr​​oid 4.4 /奇巧]

當谷歌發布Android 4.4,他們指定的應用程序下載不能再寫入到用戶安裝的MicroSD卡。應用程序仍然可以寫入內部閃存存儲。某些設備(如谷歌的Nexus設備)只有內部存儲,並不會受到影響。其他設備(如三星Galaxy和注意事項設備)必須通過安裝MicroSD卡拓展存儲空間的能力。當安裝在這些設備上奇巧,應用僅限於能夠操縱的內置存儲文件,具有寫訪問被限制的MicroSD卡。

這種變化代表了去除功能與Android 4.3相比。 4.3允許應用程序寫入MicroSD卡,就像以前的版本。

在奇巧引入的限制不影響預裝的應用程序的能力,只有應用程序,你選擇安裝。預裝的應用程序由谷歌,你的設備製造商和運營商仍然有這個能力。只是你自己選擇要安裝的應用程序受到限制。

[技術詳情]

NextApp SDFix將修改位於/系統/ etc /權限/ platform.xml允許應用程序寫入到MicroSD卡中的配置文件。具體來說,SDFix將增加Android的UNIX組“media_rw”到WRITE_EXTERNAL_STORAG​​E權限的配置。這將使應用程序(僅適用於您授予寫訪問權限,當你安裝這些那些)寫入文件到MicroSD卡。在許多設備上,這是有效地恢復此權限的狀態恢復到它被配置在安卓4.3的方式。這種修改是通過修改現有的XML文件,而不是取代它。

原來的配置文件的備份將被保存在/系統/ etc /權限/ platform.xml.original-預sdfix(提供一個不存在的話)。回复此修改可以通過使用一個根功能的文件管理器來替換/系統的/ etc與備份版本/權限/ platform.xml文件來完成。

[更多信息]

這個程序是免費的,沒有廣告(除了鏈接到其他NextApp當它完成其任務的應用程序)。

最新異動

New update keeps indentation perfect in platform.xml.

IT IS NOT NECESSARY TO RUN SDFIX AGAIN WITH THIS UPDATE. If you've run SDFix previously and it worked correctly, there is no reason to re-download or re-run the app.
