Plugins


$ cordova plugin add org.apache.cordova.battery-status

$ npm install -g plugman
$ plugman -d --platform android --plugin org.apache.cordova.battery-status

Install the battery status plugin

Using plugman

Create you own Plugin

package org.apache.cordova.plugin;

import org.apache.cordova.api.CordovaPlugin;
import org.apache.cordova.api.PluginResult;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

        if (message != null && message.length() > 0) { 
            callbackContext.success(message);
        } else {
            callbackContext.error("Expected one non-empty string argument.");
        }
    }
}

exec(<successFunction>, <failFunction>, <service>, <action>, [<args>]);
