The Android SDK includes a variety of custom tools that help you develop mobile
applications on the Android platform. The most important of these are the Android
Emulator and the Android Development Tools plugin for Eclipse, but the SDK also
includes a variety of other tools for debugging, packaging, and installing your
applications on the emulator.
- Android Development Tools Plugin (for the Eclipse IDE)
- The ADT plugin adds powerful extensions to the Eclipse integrated environment,
making creating and debugging your Android applications easier and faster. If you
use Eclipse, the ADT plugin gives you an incredible boost in developing Android
- Android Emulator
- A QEMU-based device-emulation tool that you can use to design,
debug, and test your applications in an actual Android run-time environment.
- Android Virtual Devices (AVDs)
- Virtual device configurations that you create, to model device
characteristics in the Android Emulator. In each configuration, you can
specify the Android platform to run, the hardware options, and the
emulator skin to use. Each AVD functions as an independent device with
it's own storage for user data, SD card, and so on.
- Hierarchy Viewer
- The Hierarchy Viewer tool allows you to debug and optimize your user interface.
It provides a visual representation of your layout's hierarchy of Views and a magnified inspector
of the current display with a pixel grid, so you can get your layout just right.
- Draw 9-patch
- The Draw 9-patch tool allows you to easily create a
NinePatch graphic using a WYSIWYG editor. It also previews stretched
versions of the image, and highlights the area in which content is allowed.
- Dalvik Debug Monitor
- Integrated with Dalvik, the Android platform's custom VM, this tool
lets you manage processes on an emulator or device and assists in debugging.
You can use it to kill processes, select a specific process to debug,
generate trace data, view heap and thread information, take screenshots
of the emulator or device, and more.
- Android Debug Bridge (adb)
- The adb tool lets you install your application's .apk files on an
emulator or device and access the emulator or device from a command line.
You can also use it to link a standard debugger to application code running
on an Android emulator or device.
- Android Asset
Packaging Tool (aapt)
- The aapt tool lets you create .apk files containing the binaries and
resources of Android applications.
- Android Interface
Description Language (aidl)
- Lets you generate code for an interprocess interface, such as what
a service might use.
- Included as a convenience, this tool lets you access the SQLite data
files created and used by Android applications.
- This tool produces graphical analysis views of trace log data that you
can generate from your Android application.
- Helps you create a disk image that you can use with the emulator,
to simulate the presence of an external storage card (such as an SD card).
- The dx tool rewrites .class bytecode into Android bytecode
(stored in .dex files.)
- The Monkey is a program that runs on your emulator or device and generates pseudo-random
streams of user events such as clicks, touches, or gestures, as well as a number of system-
level events. You can use the Monkey to stress-test applications that you are developing,
in a random yet repeatable manner.
- A script that lets you manage AVDs and generate Ant build files that
you can use to compile your Android applications.
