纯JAVA读取android应用程序apk包的相关信息

程序入口

package com.read.apk;public class ReadApk {/** *  * @param args * @return void * @author hsx * @time 2013-4-24下午03:20:24 */public static void main(String[] args) {String path = "./src//com//read//apk//baidushurufa.apk";String[] messag = AnalysisApk.unZip(path, "E://11");System.out.println(messag[0] + "-------->" + messag[1]);}}
