Android Device directory structure is not fixed as in normal Linux but the following are typical:
/system/bin – native utilities
/system/xbin – more native utilities
/system/etc – configuration files
/system/apps – location of apps as apk or odex files
/system/framework – application framework files (jar)
/storage/sdcard – accessible outside of the phone (rw)
/data – applications data (rw)
/proc – proc file system
/sys – sys file system
/proc/crypto – encryption/signing schemes
