can't sign android app lite version with same private key

i just signed my paid app and now i want to sign a lite version of it with the same private key. my problem now is that, am receivin开发者_运维知识库g this error:

jarsigner: unable to open jar file.

do i have to create another keystore for it? or is the problem coming from the fact that i am saving it as a different file name? what can i do? Thank you

The problem is definitely not related to the fact that it is a lite version. I find it curious that the error message is Jarsigner: Unable to open jar file.

Some searching around leads me to believe you are making some typing error in your command (please revisit the steps found here http://developer.android.com/guide/publishing/app-signing.html#signapp )

Also some other searching I did pointed to difficulties someone had with certain file names. Is your .APK name elaborate? Another instance of this problem I found ( http://coding.derkeiler.com/Archive/Java/comp.lang.java.help/2005-09/msg01002.html ) was claimed to be solved by simplifying the name.

Also make sure you are actually pointing to the .APK. Try typing out full paths to the file if you're not already.

I see an issue where i was using the full paths and it did not work, if you are having this problem, then just ensure that the .apk and the .keystore file is in the same destination. For my scenario I moved the apk to the root folder and run command and it worked. Hope this helps.
