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.

aapt
The Android Asset Packaging Tool is used to create, inspect and manage Android packages.

You can use this to see details about a package, it's resources, and xml information.

The Android developer page on aapt is somewhat meager.

See Android aapt for substantially more information.

ddms
The Dalvik Debug Monitor Server is a host-based tool which interacts with and Android target system and can show numerous bits of information, including the log, cpu and memory utilization, and lots of details about individual processes.

See the DDMS developer guide

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

traceview

 * Google's main page describing traceview: http://developer.android.com/guide/developing/tools/traceview.html
 * http://www.bottomlesspit.org/file_download/2/Android_SDK_Traceview_tool.pdf - good overview presentation by Olivier Bilodeau
 * presentation with speaker notes: http://www.bottomlesspit.org/file_download/3/Android_SDK_Traceview_tool_w_speakernotes.pdf
 * Performance Tuning Android Applications - straightforward article discussing traceview use to find an application bottleneck. April 2009.

am
Activity Manager - can be used to start applications at the command line, or send intents to running applications.

logcat
This is the main See http://developer.android.com/guide/developing/tools/adb.html#logcat

procrank
procrank shows a listing of processes on the system, sorted by one of the memory utilization metrics. See Android Memory Usage

service
Can be used to send an individual service message.

Usage: service [-h|-?] service list service check SERVICE service call SERVICE CODE [i32 INT | s16 STR] ... Options: i32: Write the integer INT into the send parcel. s16: Write the UTF-16 string STR into the send parcel.

On one forum, I saw that you could switch between portrait and landscape with: $ service call window 18 i32 1 # to set to landscape on the emulator $ service call window 18 i32 0 # to set to portrait on the emulator

service list will show a list of different services that can be communicated with.

toolbox
stop, start - commands to stop and start services on an Android system

agcc

 * agcc - A wrapper tool for compiling native Android apps (linked directly to bionic)
 * See http://android-tricks.blogspot.com/2009/02/hello-world-c-program-on-using-android.html

bootchart

 * See Using Bootchart on Android

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.

smem

 * smem - smem is a tools for analyzing the memory usage on a system
 * See Using smem on Android for more information

strace

 * strace
 * Statically linked binary available at: http://benno.id.au/blog/2007/11/18/android-runtime-strace
 * Instructions for building Android strace - http://discuz-android.blogspot.com/2008/01/create-google-android-strace-tool.html

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.
