Android 4.0.3 Emulator File System Hierarchy
This section describes file system hierarchy used by the Android 4.0.3 emulator system.
On an Android system, file systems are mounted into a single file system hierarchy.
After connecting to the Android 4.0.3 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 cache - Folder used as scratch pad by the system data - Folder for USER Data stored as a separate partition anr app - Folder for user installed application package .apk files dalivk-cache data - Folder for application data with package name as sub folder 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 programm configuration files init - File with initial execution code init.rc - File with initial configurations proc - Folder for running process pointers ... cpuinfo - File with current CPU information diskstats - File with disk statuses ... root sbin - Folder for binary executable codes adbd - File with Android Debug Bridge Daemon (adbd) executable code sys 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 framework Folder for JAR and ODEX files of Android framework fonts - Folder for font files media - Folder for media files xbin - Folder for binary executable files. sdcard - Folder for files in the removable SD Card. mnt - Folder for file system mount points
