纯JAVA环境获取APK信息(包名,版本,版本号,大小,权限...),纯JAVA语言编写PC端获取APK信息

纯JAVA环境获取APK信息:包名,版本,版本号,大小,权限...

纯Java环境获取APK信息需要两个包:AXMLPrinter2.jar 跟jdom.jar,用于反编译XML和解析XML的

这个类是获取APK信息的

public class ApkUtil {
	
	private static final Namespace NS = Namespace.getNamespace("http://schemas.android.com/apk/res/android");
	
	@SuppressWarnings("unchecked")
	public static String getApkInfo(String apkPath){
		ApkInfo apkInfo = new ApkInfo();
		SAXBuilder builder = new SAXBuilder();
		Document document = null;
		try{
			document = builder.build(getXmlInputStream(apkPath));
		}catch (Exception e) {
			e.printStackTrace();
		}
		Element root = document.getRootElement();//跟节点-->manifest
		apkInfo.setVersionCode(root.getAttributeValue("versionCode",NS));
		apkInfo.setVersionName(root.getAttributeValue("versionName", NS));
		apkInfo.setApkPackage(root.getAttributeValue("package", NS));
		Element elemUseSdk = root.getChild("uses-sdk");//子节点-->uses-sdk
		apkInfo.setMinSdkVersion(elemUseSdk.getAttributeValue("minSdkVersion", NS));
		List listPermission = root.getChildren("uses-permission");//子节点是个集合
		List permissions = new ArrayList();
		for(Object object : listPermission){
			String permission = ((Element)object).getAttributeValue("name", NS);
			permissions.add(permission);
		}
		apkInfo.setUses_permission(permissions);
		
		String s = root.getAttributes().toString();
		String c[] = s.split(",");
		String versionCode = null;
		String versionName = null;
		String packageName = null;
		for(String a: c){
			if(a.contains("versionCode")){

			}
		}
		System.out.println("\n版本号:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName);
		String str = "\n版本号:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName;
//		return root.getAttributes().toString();
		return str;
	}

	private static InputStream getXmlInputStream(String apkPath) {
		InputStream inputStream = null;

			try {
				inputStream.close();
				zipFile.close();
			} catch (IOException e1) {
				e1.printStackTrace();

		return xmlInputStream;
	}

}

直接上代码,下次再补过讲解.

纯JAVA环境获取APK信息(包名,版本,版本号,大小,权限...),纯JAVA语言编写PC端获取APK信息_第3张图片 

这里只查了包名,版本,版本号,大小,没有查权限,权限被我屏蔽掉了

List listPermission = root.getChildren("uses-permission");//子节点是个集合
		List permissions = new ArrayList();
		for(Object object : listPermission){
			String permission = ((Element)object).getAttributeValue("name", NS);
			permissions.add(permission);
		}
		apkInfo.setUses_permission(permissions);

这一段就是获取权限的代码


有时候有些apk信息读不出,只要将下面这些代码注释掉就行了

		apkInfo.setVersionCode(root.getAttributeValue("versionCode",NS));
		apkInfo.setVersionName(root.getAttributeValue("versionName", NS));
		apkInfo.setApkPackage(root.getAttributeValue("package", NS));
		Element elemUseSdk = root.getChild("uses-sdk");//子节点-->uses-sdk
		apkInfo.setMinSdkVersion(elemUseSdk.getAttributeValue("minSdkVersion", NS));
		List listPermission = root.getChildren("uses-permission");//子节点是个集合
		List permissions = new ArrayList();
		for(Object object : listPermission){
			String permission = ((Element)object).getAttributeValue("name", NS);
			permissions.add(permission);
		}
		apkInfo.setUses_permission(permissions);
