I am using the netbeans android plugin for app development. I finally came to submit my app but had a lot of trouble with a ZipException when trying to digitally sign the application.
After a lot of googling, here’s how to solve the problem.
Add the following to the file
``` {.js name=”code”}
```
Right click on build.xml and select run target -> unsigned
You know have an unsigned version (***-unsigned.apk) of your app ready to be signed as in this post: Signing your android app
