Ｑ：Which versions of Android/Linux you are supporting?
Ａ：Since our source code is independent to Linux or Android versions, fast-booting can be applied to any Linux or Android version. Currently our technology works well on Android 2.2 -4.4 and Kernel 2.6 - 3.4.
Ｑ：On what stage does the restoration process start? (boot loader / linux kernel / Android framework, etc)
Ａ：The restoration process starts after the Linux kernel. Theoretically, we also support resuming from boot loader. However, resuming from Linux kernel is more portable and stable.
Ｑ：How large is the hibernation image size?
Ｑ：Can you give an example of the improvement of boot time?
Ａ：We successfully shortened the booting time from 50 seconds to 12 seconds in an Android camera phone (Altek Leo). While testing on beagleboard, the booting time can be optimized from 20 seconds to 6 seconds by fastBooting.
Ｑ：Will the total number of applications (APKs) affects the boot time? Are all the Android serves ready after booting?
Ａ：No. The number of applications is not a factor of booting time. After booting process completed, all the Android services on the device is ready to run.
Ｑ：How long does it take to make the hibernation image on Android?
Ａ：The time of rebuilding a hibernation image is about 6 seconds in most cases on beagleboard. The rebuilding time after installing an application is about 9 seconds.
Ｑ： Based on your experience, how many man-hours does integration effort take?
Ａ：The integration time heavily depends on whether your system has already support hibernation/resume. If you do, the integration effort takes about 48 man-hours.
Ｑ：Is it possible to keep the latest status when a user change the configuration without rebuilding hibernation file?
Ａ：It is possible. However, the system designer must ensure these applications always reload the configuration file after resuming.
Ｑ：When do you build the hibernation file?
Ａ：We can build hibernation file in the following two cases
Ｑ：What algorithms do you use to compress the snapshot image? (LZ4, LZO, zlib, etc)
Ａ：We support all these compress algorithms.
Ｑ：Could you give the hardware specs in the demo video？
Ａ：Altek Leo camera-phone:
Android 2.1, ARM 9@800MHz, 256MB ROM, 256MB RAM, Samsung S3C2440
Beagleboard evaluation board:
Android 2.2, ARM Cortex A8@1GHz, 512MB DRAM, Class 10 microSD
Ｑ：What is the minimum system requirement ?
Ａ：The platform should has at least one flash storage and support hibernation mode.
