java解析apk包具体，获得对应的包名和版本信息。代码如下

package test.com.core.apk2;

import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

import org.apache.commons.lang.StringUtils;
import org.xmlpull.v1.XmlPullParser;

import android.content.res.AXmlResourceParser;
import android.util.TypedValue;
