Is it possible to gain root and/or install BusyBox on the Android Emulator?

It'd be nice to have the "Swiss Army knife" of BusyBox on my emulator. It would also be nice to h开发者_运维技巧ave full root access. Does anyone have any experience doing this? I'm not familiar with qemu; is this even possible?

Update: The emulator has root by default (accessed via the adb shell command). Does anyone know where I can easily obtain a pre-built busybox binary?

The emulator is not set to secure mode, so it's adb shell should be a root shell.

There are several android builds of busybox, for example cyanogen alternative versions of Android use it to augment toolbox (which is Android's own limited re-implementation of the same concept under a non-gpl license). You should be able to get it from the cyanogen repositories and build it from source, or it's possible that just extracting the binaries from a same-android-version cyanogen update.zip would work (it may be in a compressed file system inside the update though)

There were also some writeups from pioneers who discovered the accidental root shell on the original G1 release and installed quite a bit of debian arm.
