純JAVA環境擷取APK資訊(包名,版本,版本號碼,大小,許可權...),純JAVA語言編寫PC端擷取APK資訊，apk包名

純JAVA環境擷取APK資訊:包名,版本,版本號碼,大小,許可權...

純Java環境擷取APK資訊需要兩個包:AXMLPrinter2.jar 跟jdom.jar,用於反編譯XML和解析XML的

項目目錄

這個類是擷取APK資訊的

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();//跟節點-->manifestapkInfo.setVersionCode(root.getAttributeValue("versionCode",NS));apkInfo.setVersionName(root.getAttributeValue("versionName", NS));apkInfo.setApkPackage(root.getAttributeValue("package", NS));Element elemUseSdk = root.getChild("uses-sdk");//子節點-->uses-sdkapkInfo.setMinSdkVersion(elemUseSdk.getAttributeValue("minSdkVersion", NS));List listPermission = root.getChildren("uses-permission");//子節點是個集合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")){versionCode = a.substring(a.indexOf("versionCode=\"")+13, a.lastIndexOf("\""));}if(a.contains("versionName")){versionName = a.substring(a.indexOf("versionName=\"")+13, a.lastIndexOf("\""));}if(a.contains("package")){packageName = a.substring(a.indexOf("package=\"")+9, a.lastIndexOf("\""));}}System.out.println("\n版本號碼:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName);String str = "\n版本號碼:"+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;InputStream xmlInputStream = null;ZipFile zipFile = null;try {zipFile = new ZipFile(apkPath);ZipEntry zipEntry = new ZipEntry("AndroidManifest.xml");inputStream = zipFile.getInputStream(zipEntry);AXMLPrinter xmlPrinter = new AXMLPrinter();xmlPrinter.startPrinf(inputStream);xmlInputStream = new ByteArrayInputStream(xmlPrinter.getBuf().toString().getBytes("UTF-8"));} catch (IOException e) {e.printStackTrace();try {inputStream.close();zipFile.close();} catch (IOException e1) {e1.printStackTrace();}}return xmlInputStream;}}

直接上代碼,下次再補過講解.

下面這個是一個介面的主類,主要讀取APK位置和大小

執行個體測試,這是在金山找的

 

這裡只查了包名,版本,版本號碼,大小,沒有查許可權,許可權被我屏蔽掉了

List listPermission = root.getChildren("uses-permission");//子節點是個集合List permissions = new ArrayList();for(Object object : listPermission){String permission = ((Element)object).getAttributeValue("name", NS);permissions.add(permission);}apkInfo.setUses_permission(permissions);

這一段就是擷取許可權的代碼

有時候有些apk資訊讀不出,只要將下面這些代碼注釋掉就行了

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