Android – jarsigner cannot open the jar file: nooyawk.apk. (nooyawk is the application name)

I signed my map application here with my publishing key through this link

http://developer.android.com/guide/publishing/app-signing.html#cert

After generating the debugging key, the next step is to generate the release map key by using the certificate signature. I'm doing this normally, but jarsigner can't find my nooyawk.apk file in the end

What should I do

Thank you in advance

Unless nooyawk.apk is in your current working directory, you need to provide the full path of APK file
