If someone knows your SHA-1 certificate fingerprint: : i'm trying to obtain SHA-1 certificate fingerprint with the command "keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android"

and clicked in jdk folder and opened windows power shell but returned this error to me..."keytool : The term 'keytool' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1

I think this error occur because of I didn't set path in System Environment Variables ... I gone to it but in variables path not exist to edit....
I use windows 10 ver.1709 build16299.371
