java从apk文件里获取包名、版本号

测试代码：

package org.apkinfo.test;

import java.io.IOException;
import java.util.ArrayList;

import org.apkinfo.api.GetApkInfo;
import org.apkinfo.api.domain.ApkInfo;

public class GetApkInfoTest {
	public static void main(String[] args) {
		try {
			ArrayList<ApkInfo> listAPKInfo = GetApkInfo.listApkInfoByDir("D:\\DefaultApkTempSaveFolder\\3D风景动态壁纸\\");
			System.out.println(listAPKInfo);
			
			ApkInfo apkInfo = GetApkInfo.getApkInfoByFilePath("D:\\DefaultApkTempSaveFolder\\3G安卓市场\\com.jiubang.market.apk");
			System.out.println(apkInfo);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

运行结果：

[ApkInfo [packageName=cn.bighead.livewallpaper.fengjing3D123, versionName=1.4.7, versionCode=147]]

ApkInfo [packageName=com.jiubang.market, versionName=3.2.6, versionCode=35]
