純JAVA環境獲取APK資訊:包名,版本,版本號,大小,許可權...
純Java環境獲取APK資訊需要兩個包:AXMLPrinter2.jar 跟jdom.jar,用於反編譯XML和解析XML的
專案目錄
這個類是獲取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-->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");//子節點-->uses-sdk apkInfo.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:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName); String str = "\n版本號:"+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; } }
直接上程式碼,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

例項測試,這是在金山找的
這裡只查了包名,版本,版本號,大小,沒有查許可權,許可權被我遮蔽掉了
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);
這一段就是獲取許可權的程式碼
有時候有些apk資訊讀不出,只要將下面這些程式碼註釋掉就行了
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-sdk
apkInfo.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);尊重原創,轉載請註明出處:http://blog.csdn.net/chillax_li/article/details/41850863
