Create an android Environment

As an android developer, how to download compiled AMSS and AP images to your mobile phone is the first step in creating a development environment and a test environment
1. Download and decompress the android driver package.
Currently, Google adds more new features to the smartphone operating system andriod, with the Development code "cupcake". In the new Android version, the Linux kernel will be upgraded.

Up to 2.6.27, the browser core was also upgraded to support and support the new squirrelfish JavaScript Engine.

(2) ADB Shell
(3) busybox fdisk/dev/block/mmcblk0 will display the partition list
Busybox fdisk/dev/block/mmcblk0
The following information is returned after the command is entered:
The number of cylinders for this disk is set to 245760.
There is nothing wrong with that, but this is larger than 1024,
And coshould in certain setups cause problems:
1) software that runs at boot time (e.g., old versions of lilo)
2) booting and partitioning software from other OSS
(E.g., DOS fdisk, OS/2 fdisk)

Command (M for help ):
Command (M for help): Input n to create a new partition. Input P to select the primary partition. Enter m to obtain command information.
