apkUtil是一个用来解析apk安装包的工具，通过它可以获取一个安装包的图标、程序名、所需android平台，权限等信息，并将其转换为java对象。该工具依赖于aapt工具，目前仅支持在windows平台上运行。 程序在运行时，会创建一个进程，用于运行aapt。默认的aapt的路径为jar包相对目录的lib/aapt。如果路径更改，请使用setAaptPath方法。

新的版本使用方法如下：

                try {
                        String demo = "E:/androidApk/2012/05/百宝工具箱/1.0/signed/Toolbox-360.apk";
                        if (args.length > 0) {
                                demo = args[0];
                        }
                        ApkInfo apkInfo = new ApkUtil().getApkInfo(demo);
                        System.out.println(apkInfo);
                } catch (Exception e) {
                        e.printStackTrace();
                }

输出结果如下：

ApkInfo [versionCode=1,
  versionName=1.0,
  packageName=cfuture.xiaozhi.toolbox,
  minSdkVersion=null,
  usesPermissions=[android.permission.ACCESS_FINE_LOCATION, android.permission.ACCESS_NETWORK_STATE, android.permission.ACCESS_WIFI_STATE, android.permission.INTERNET, android.permission.MOUNT_UNMOUNT_FILESYSTEMS, android.permission.READ_LOGS, android.permission.READ_PHONE_STATE, android.permission.WRITE_EXTERNAL_STORAGE, android.permission.READ_EXTERNAL_STORAGE],
  sdkVersion=4,
  targetSdkVersion=null,
  applicationLable=百宝工具箱,
  applicationIcons={application-icon-240=res/drawable-hdpi/toolbox.png, application-icon-160=res/drawable-mdpi/toolbox.png, application-icon-120=res/drawable-ldpi/toolbox.png},
  applicationIcon=res/drawable-mdpi/toolbox.png,
  impliedFeatures=[Feature [feature=android.hardware.location, implied=requested a location access permission], Feature [feature=android.hardware.location.gps, implied=requested android.permission.ACCESS_FINE_LOCATION permission], Feature [feature=android.hardware.wifi, implied=requested android.permission.ACCESS_WIFI_STATE, android.permission.CHANGE_WIFI_STATE, or android.permission.CHANGE_WIFI_MULTICAST_STATE permission], Feature [feature=android.hardware.touchscreen, implied=assumed you require a touch screen unless explicitly made optional], Feature [feature=android.hardware.screen.landscape, implied=one or more activities have specified a landscape orientation], Feature [feature=android.hardware.screen.portrait, implied=one or more activities have specified a portrait orientation]],
  features=[android.hardware.location, android.hardware.location.gps, android.hardware.wifi, android.hardware.touchscreen, android.hardware.screen.landscape, android.hardware.screen.portrait]]

注意：以前的apkUtil 0.x版本已经弃用，原因是其效率低下，且获得的信息较少。
