You are getting that pop-up because you have the option to wipe user data option selected for your project.

To turn it off, go to Run -> Run Configurations... When the Run Configurations window comes up, choose your Android application if necessary. Then go to the Target tab. Scroll down and you'll see a check box that says, "Wipe User Data." Uncheck that box, and you will not see that pop up again.

change the path of the SDK your path is Program Files\Android\android-sdk-tools/. put SDK directly in the drive ie. d:\Android\android-sdk-tools

note: also remove spaces from the path by renaming the folder name

Go to your Eclipse --> Window --> Android Virtual Device Manager --> Select your virtual device and click Start There's an option called Wipe Data for you to clear all user data
