keytool error          


        

Answer 1

I have faced an error while trying to export a signed .apk file with Eclipse ADT. The error was same like your error. In my case, I used a + sign before the country code. By removing the + sign from this name fixed the problem and allowed me to fully export my signed .apk file. Also, this error can occur when use comma,slash, semi-colon, quotation.
