Answer 1

Please check your ANDROID_HOME as appium is not able to find build tool :

ANDROID_HOME =C:\\Users\\Ramoji\\AppData\\Local\\Android\\Sdk'

In Path environment set location till build-tools directory : C:\\Users\\Ramoji\\AppData\\Local\\Android\\sdk\\platform-tools\\build-tools

or %ANDROID_HOME%\\platform-tools\\build-tools.

Also check in Eclipse Eclipse -> Run Configurations -> Environments tab if any wrong path is set
