==Testbed==
TBDAs stated in the introduction, the solution has been tested on a platform running Android 4.4.3. From the software standpoint, this platform is a good example of an implementation where significant changes have been done to use Android on an industrial embedded device. Some of these changes modify the Android security model. In many cases, this is acceptable because the overall security of the product is not compromised (for instance, many devices used for industrial applications are not connected to the Internet and the physical access is granted to authorized personell only). The following is a not exhaustive list of the changes with respect to the standard/typical Android configuration used on mobile devices:*As the non-volatile storage device is a NAND flash, UBIFS file system has been used*There is only one partition*The file system is read/write; as such, the <code>system</code> directory is writeable as well*A serial console is available on a UART port; <code>root</code> login is allowed on this console*U-Boot has been used as bootloader.
Development have been performed on the following platform:
