Android Tools

Here are some development tools useful for working with Android

adb
adb is the android debugger - it also doubles as file transfer agent. The setup consists of an adbd on the target in the /sbin directory. On the host two programs are run: the adb application (in the SDK's tools directory) and an adb server, started by the adb application.

For emulators, adb will usually run automagically.

For real boards - with debugging over USB, you might need to do work, as is documented here: http://developer.android.com/guide/developing/device.html#setting-up.

For real boards that do not have a USB connection but have Ethernet instead, you might need to do a few tricks. ADBHOST= tools/adb kill-server ADBHOST= tools/adb shell
 * make sure that adbd runs on the board. If it doesn't run, you might want to check the init.rc file.
 * make sure that the network connection between host and the board is working - test pinging both ways.
 * on the host, type the following (and yes, you need to specify the board's IP address on the host):
 * you should now get a prompt on the board, you can exit the prompt if you want.
 * tools/adb devices should now list the device.

fastboot

 * Fastboot - Android Fastboot is a tool to boot and manipulate the partitions on an Android development phone.

The emulator is a version of QEMU, which mimics the instruction set of an ARM processor, and the hardware that one might find on a mobile phone. The emulator runs on an x86 system, but executes an ARM linux kernel and programs. The flow of control is:
 * toolchains -
 * logging system -
 * Emulator - See http://developer.android.com/guide/developing/tools/emulator.html
 * application ->
 * dalvik VM ->
 * C/C++ libraries ->
 * ARM linux kernel ->
 * emulated instructions and hardware (QEMU)->
 * C libraries->
 * x86 kernel ->
 * real hardware

busybox
Android ships with a utility suite (called 'toolbox') that is not busybox.

You can get a binary busybox for Android here The site includes instructions for easy installation on your device.

Serial Cable for G1
You can build a serial cable to use with the G1, which is helpful to see kernel boot messages on the serial console.
