Android / Eclipse: where to write command lines like "-wipe-data emulator"?

Question

Many blogs mention how to write command lines to do different things ... but I don’t know where to write these command lines! For example, I want to clear the emulator using emulator -wipe-data , but where should I put this?

Answer 1

Open a command prompt and click

 android-sdk-windows\tools 

Then for the following command:

 emulator -avd -wipe-data 

use something like:

 emulator -avd myandroidavd -wipe-data 

Answer 2

To set the cleaning option on a Mac, when you start the Android SDK Manager, click the "Start" button to start AVD. The Launch Options window opens. There is a “Clear user data” checkbox about halfway down.
