The Android Plugin for Eclipse is a complete solution to start Android applications emulator development where you can use the specific emulator to test your code.
The Android SDK comes with a command-line environment as well. From there you can launch commands to perform some actions useful in the development and the debugging process.
One of the bug in the emulator is that sometime you launch it from Eclipse but it doesn't start your application and it stucks on its main screen. To solve this problem, you have to go to the command line and launch the command "adb kill-server".
To use the command line tools, be sure you have the "tools" folder of Android SDK in your environment PATH variable.
