Android 5.1.1 Emulator File System Hierarchy
This section describes file system hierarchy used by the Android 5.1.1 emulator system.
On an Android system, file systems are mounted into a single file system hierarchy.
After connecting to the Android emulator with the "adb shell" command, I used "cd" and "ls" shell commands to explore the file system hierarchy. Here is what I see:
/ - Base file system acct - The mount point for the acct cgroup (control group), which provides for user accounting cache - A folder used as scratch pad by the system charger - A symbolic link to /sbin/healthd config - An empty folder d - A symbolic link to /sys/kernel/debug. data - Folder for user data stored as a separate partition adb - An empty folder for Android Debug Bridge anr - Folder for traces.txt usded by dalvikvm to dump stack trace app - Folder for user installed application package .apk files app-asec app-private dalivk-cache backup bugreports dalvik-cache data - Folder for application data with package name as sub folder dontpanic drm local ... system default.prop - File with default system settings dev - Folder of device pointers block - Folder of block device pointers ... null tty1 tty2 tty3 etc - Folder for program configuration files file_contexts fstab.goldfish init - A binary program that processes the init.rc file. init.rc - File with initial configurations mnt - A mount point for other file systems proc - A mount point for the procfs file system, which provides access to kernel data structures. ... cpuinfo - File with current CPU information diskstats - File with disk statuses ... version root - The home folder for the root account. sbin - Folder for binary executable codes adbd - File with Android Debug Bridge Daemon (adbd) executable code sdcard - A symbolic link to /storage/sdcard storage - sys - A mount point for sysfs pseudo file system for kernel objects system - Folder for the operating system files - read only app - Folders for pre-installed application package .apk files bin - Folder for system binary executable codes build.prop - File containing configuration settings etc - Folder for configuration files fonts - Folder for font files framework - Folder for JAR and ODEX files of Android framework lib - Folder contains binary code libraries like libc.so media - Folder for media files priv-app tts usr vendor xbin - Folder for binary executable files vendor - A symbolic link to /system/vendor
