5. • AVD - Android Virtual Device
– Simulates a device and/or Android version (Level) image
used for emulator execution
– It can be launched using IDE or emulator command in CLI
– emulator.exe -avd NXT-AVD-2.3.3 -netspeed full -netdelay none
– emulator.exe -avd NXT-AVD-2.3.3 -netspeed full -netdelay none -verbose
– emulator.exe -avd NXT-AVD-2.3.3 -netspeed full -netdelay none
– emulator.exe -avd NXT-AVD-2.3.3 -netspeed full -netdelay none -version
– AVD Manager

6. • ADB - Android Debug Bridge
– ADB allows us to communicate with devices or emulator
instances. Very useful bridge!
– It is a client/server application that runs on device and on
workstation
– http://developer.android.com/tools/help/adb.html
– Some ADB command examples:
• adb <comando>
• adb -- help
• adb devices
• adb logcat

9. • The DDMS Perspective
– Dalvik Debug Monitor Service (DDMS) is a debugging tool that allows us to use and
perform several debug tasks:
• Devices - Shows the list of devices and AVDs that are connected to ADB.
• Emulator Control - Lets you carry out device functions.
• LogCat - Lets you view system log messages in real time.
• Threads - Shows currently running threads within a VM.
• Heap - Shows heap usage for a VM.
• Allocation Tracker - Shows the memory allocation of objects.
• File Explorer - Lets you explore the device's file system.
