| <p>Below are examples of external storage configurations as of Android 4.4 |
| for various typical devices. Only the relevant portions of the configuration |
| files are included. |
| |
| <h2>Physical primary only (like Nexus One)</h2> |
| |
| <p>This is a typical configuration for a device with single external storage |
| device which is a physical SD card.</p> |
| |
| <p>The raw physical device must first be mounted under |
| <code>/mnt/media_rw</code> where only the system and FUSE daemon can access |
| it. <code>vold</code> will then manage the <code>fuse_sdcard0</code> service |
| when media is inserted/removed. |
| |
| <h3>fstab.hardware</h3> |
| |
| <pre><code>[physical device node] auto vfat defaults voldmanaged=sdcard0:auto,noemulatedsd |
| </code></pre> |
| |
| <h3>init.hardware.rc</h3> |
| |
| <pre><code>on init |
| mkdir /mnt/media_rw/sdcard0 0700 media_rw media_rw |
| mkdir /storage/sdcard0 0700 root root |
| |
| export EXTERNAL_STORAGE /storage/sdcard0 |
| |
| service fuse_sdcard0 /system/bin/sdcard -u 1023 -g 1023 -d /mnt/media_rw/sdcard0 /storage/sdcard0 |
| class late_start |
| disabled |
| </code></pre> |
| |
| <h3>storage_list.xml</h3> |
| |
| <pre><code><storage |
| android:mountPoint="/storage/sdcard0" |
| android:storageDescription="@string/storage_sd_card" |
| android:removable="true" |
| android:primary="true" |
| android:maxFileSize="4096" /> |
| </code></pre> |
| |
| |
| <h2>Emulated primary only (like Nexus 4)</h2> |
| |
| <p>This is a typical configuration for a device with single external storage |
| device which is backed by internal storage on the device.</p> |
| |
| <h3>init.hardware.rc</h3> |
| |
| <pre><code>on init |
| mkdir /mnt/shell/emulated 0700 shell shell |
| mkdir /storage/emulated 0555 root root |
| |
| export EXTERNAL_STORAGE /storage/emulated/legacy |
| export EMULATED_STORAGE_SOURCE /mnt/shell/emulated |
| export EMULATED_STORAGE_TARGET /storage/emulated |
| |
| on fs |
| setprop ro.crypto.fuse_sdcard true |
| |
| service sdcard /system/bin/sdcard -u 1023 -g 1023 -l /data/media /mnt/shell/emulated |
| class late_start |
| </code></pre> |

| <h3>storage_list.xml</h3> |
| |
| <pre><code><storage |
| android:storageDescription="@string/storage_internal" |
| android:emulated="true" |
| android:mtpReserve="100" /> |
| </code></pre> |
| |
| |
| <h2>Emulated primary, physical secondary (like Xoom)</h2> |
| |
| <p>This is a typical configuration for a device with multiple external |
| storage devices, where the primary device is backed by internal storage |
| on the device, and where the secondary device is a physical SD card.</p> |
| |
| <p>The raw physical device must first be mounted under |
| <code>/mnt/media_rw</code> where only the system and FUSE daemon can |
| access it. <code>vold</code> will then manage the <code>fuse_sdcard1</code> |
| service when media is inserted/removed.</p> |
