This post is old, but just to help other who will end up here with the same question. I solved it when I copied the generated keystore to the apk dir and ran the jarsigner in a console set to the apk path.

Use this command on command prompt when put the keystore file and apk file both in same folder and reach that folder and enter this command and it asking for password enter same password when created the keystore file

for genrating the keystore and after that create the keystore file inside the user folder

keytool -genkey -v -keystore appname.keystore -alias appname -keyalg RSA -keysize 2048 -validity 10000

and reach this folder use this one

 jarsigner -keystore appname.keystore apkname.apk appname

Might be a corrupt jar.

To rule that out add a .zip extension to the end of the file to see if you can then unzip that file. If you can't then thats your problem. If it unzips, then its something else.
