The "SmartDocs" bar can customize this page to show only the features present on a particular Zebra device.
OSX, MX and Android version information for a device can be found in the Android Settings panel or by querying the device through ADB, EMDK or the MX CSP. More info.
The SD Card Manager (SdCardMgr) controls the use of device storage, primarily as a security measure on devices that support a physically removable storage medium such as a Micro SD Card.
When a device supports physically removable storage, it is sometimes necessary to prevent access to such media so that unwanted software cannot be loaded onto the device or sensitive data be removed. Preventing the use of removable media greatly reduces such risks.
On devices that support a removable storage medium, that medium is the default target of the Usage parameter of this CSP. Otherwise, the Primary Storage Card is the target.
/sdcard and /storage
for applowing apps to access each of the supported Storage Cards within a device. Paths such as /storage/sdcard0 and /storage/sdcard1 are supported when multiple Storage Cards are implemented. /sdcard0 links to /storage/sdcard0.Note: While the term "card" might imply a removable medium, the primary (and secondary) "Storage Card(s)" in most Zebra devices are simulated using flash memory that's built into the device and cannot be removed. On devices that support a physically removable medium such a Micro SD Card, such storage will be identified and accessed using similar terminologies.
The number and type of supported Storage Cards and their access paths vary by device, particularly on Jelly Bean.
Fewer storage-term variations exist on KitKat devices, and relate mainly to removable memory and the amount of built-in memory on the device.
Storage Cards can be accessed in multiple ways, including through built-in privileged System apps, installed unprivileged apps, and from computers using MTP or ADB over USB.
If access to a Storage Card is disabled using the SdCardMgr, all access to that Storage Card is blocked, without exception, until access is re-enabled using the SdCardMgr.
Removable media can become inaccessible by means other than blockage by this CSP. For example, an unblocked Micro SD Card will be inaccessible if physically removed from the device or if encrypted and the Named Key has been removed from the Key Storage Database (see EncryptMgr).
Used to control access to external device storage, which can include an SD card or USB-connected storage media. When Enabled (option 1), access to all external storage is completely blocked.
Note: Removable media can become inaccessible by means other than blockage by this CSP. For example, an unblocked Micro SD card is inaccessible if physically removed from the device or if encrypted and the Named Key has been removed from the Key Storage Database (see EncryptMgr).
Parm Name: SdCardUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to Storage Card usage on a device; any previously selected setting is retained. |
