Cordova plugin to provide zip functionality on hybrid applications, such as on those made with Ionic framework. The Java code is mostly borrowed from StackOverflow and so, I've done preprocessing in Javascript. Change it as it may suit you.

The official cordova plugin for zipping failed for me, resulting in bad zip. I tried to debug it but couldn't so I thought why not make a simpler one which gaurantees solution.

Install the plugin by using following command:

cordova plugin add cordova-plugin-eszip

Thereafter, the global object ESzip will be available in your app. Please note that this will not run on browsers so please test on actual devices/simulators only.

• ESzip exposes function zipFolder, using which you can zip your source folder into destination zip file. Please note that source and destination are meant to be absolute paths, wherein source has to be an existing directory/file.
• zipFolder requires 4 parameters, namely: source, destination, successCallback, and errorCallback. source and destination have to be absolute file URLs.

 angular.module('starter.services',[])
 .factory('$zip', function($q)
 {
   return {
    zip: function(src, dest)
    {
        var deferred = $q.defer();
        ESzip.zipFolder(src, dest, function(result)
        {
            if(result && result.success)//just to be sure
                deferred.resolve(result);
            else
                deferred.reject(result);
        },
        function(err){
            console.error(err);
            deferred.reject(err);
        })
        return deferred.promise;
    }
   };
 });
