How to install Busybox on a simulator?

1)      Download Busybox image from http://www.busybox.net/downloads/binaries/1.21.1/

2)      Because the /system partition is read-only by default.

#remounts the /system and /vendor (if present) partitions on the device read-write

adb remount

3)      adb push busybox-armv71 /system/xbin/busybox

4)      adb shell

cd /system/xbin/

chmod 755 ./busybox

5)      Then, you can run busybox.

        BusyBox is a multi-call binary that combines many common Unix

        utilities into a single executable.  Most people will create a

        link to busybox for each function they wish to use and BusyBox

        will act like whatever it was invoked as.
