ExtractZipFile for cordova 2.3.0 android

Question

我想知道如何將ExtractZipFile插件獲取到最新的cordova 2.3。我試圖讓插件工作，但沒有贏。

鏈接插件 https://github.com/phonegap/phonegap-plugins/tree/master/Android/ExtractZipFile

希望有人能幫助我。

我修改維沙爾Rajpal代碼遵從科爾多瓦插件結構，如在Plugin Development Guide和Developing a Plugin on Android記錄（所述ExtractZipFile插件的作者）。

Java代碼被放在src目錄下的組織/阿帕奇/科爾多瓦/插件/ ExtractZipFilePlugin.java

package org.apache.cordova.plugin;

import org.apache.cordova.api.CallbackContext; 
import org.apache.cordova.api.CordovaPlugin; 
import org.apache.cordova.api.PluginResult; 

public class ExtractZipFilePlugin extends CordovaPlugin 
{ 
    @Override 
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException 
    { 
     if (action.equals("unzip")) 
     { 
      String filename = args.getString(0); 
      unzip(filename, callbackContext); 
      return true; 
     } 

     return false; 
    } 

    private void unzip(String filename, CallbackContext callbackContext)

     File file = new File(filename); 
     String[] dirToSplit = filename.split(File.separator); 
     String dirToInsert = ""; 

     for (int i = 0; i < dirToSplit.length - 1; i++) 
     { 
      dirToInsert += dirToSplit[i] + File.separator; 
     } 

     BufferedOutputStream dest = null; 
     BufferedInputStream is = null; 
     ZipEntry entry; 
     ZipFile zipfile; 

     try 
     { 
      zipfile = new ZipFile(file); 
      Enumeration<? extends ZipEntry> e = zipfile.entries(); 

      while (e.hasMoreElements())

       int count; 
       byte data[] = new byte[102222]; 
       String fileName = dirToInsert + entry.getName(); 
       File outFile = new File(fileName); 

       if (entry.isDirectory()) 
       { 
        outFile.mkdirs(); 
       } 
       else 
       { 
        FileOutputStream fos = new FileOutputStream(outFile); 
        dest = new BufferedOutputStream(fos, 102222); 

        while ((count = is.read(data, 0, 102222)) != -1) 
        { 
         dest.write(data, 0, count);

     catch (IOException e1) 
     { 
      callbackContext.error(PluginResult.Status.IO_EXCEPTION.toString()); 
      return; 
     } 

     callbackContext.success(filename); 
    } 
} 

插件聲明被放在RES/XML /配置。在插件的xml

<plugin name="ZipPlugin" value="org.apache.cordova.plugin.ExtractZipFilePlugin" /> 

JavaScript代碼要包含在你的項目 - 文件ZipPlugin.js

/*

    Created Date: 21-02-2012 
    Modified Date: 21-02-2013

*/ 

var ExtractZipFilePlugin = function() 
{ 
}; 

ExtractZipFilePlugin.prototype.extractFile = function(file, successCallback, errorCallback) 
{ 
    cordova.exec(successCallback, errorCallback, "ZipPlugin", "unzip", [file]); 
}; 

使用例如

var ZipClient = new ExtractZipFilePlugin(); 
ZipClient.extractFile("my_path/my.zip", win, fail); 

function win(status) 
{  
    alert('Success ' + status); 
}  

function fail(error) 
{ 
    alert(error); 
} 

與科爾多瓦成功測試2.4.0
乾杯！

我也面臨同樣的問題，比我修改，這PhoneGap的插件解壓在2.6
