Java解析 APK AndroidManifest.xml

参考文档：http://www.cnblogs.com/ITtangtang/p/3881288.html

获取Android版本信息，就需要解析AndroidManifest.xml文件。代码如下：

public class ApkUtil {public static final String VERSION_CODE = "versionCode";public static final String VERSION_NAME = "versionName";public static final String SDK_VERSION = "sdkVersion";public static final String TARGET_SDK_VERSION = "targetSdkVersion";public static final String USES_PERMISSION = "uses-permission";public static final String APPLICATION_LABEL = "application-label";public static final String APPLICATION_ICON = "application-icon";public static final String USES_FEATURE = "uses-feature";public static final String USES_IMPLIED_FEATURE = "uses-implied-feature";public static final String SUPPORTS_SCREENS = "supports-screens";public static final String SUPPORTS_ANY_DENSITY = "supports-any-density";public static final String DENSITIES = "densities";public static final String PACKAGE = "package";public static final String APPLICATION = "application:";public static final String LAUNCHABLE_ACTIVITY = "launchable-activity";private ProcessBuilder mBuilder;private static final String SPLIT_REGEX = "(: )|(=')|(' )|'";//private static final String FEATURE_SPLIT_REGEX = "(:')|(',')|'";public ApkUtil() {mBuilder = new ProcessBuilder();mBuilder.redirectErrorStream(true);}/** * 返回一个apk程序的信息。 *  * @param mAaptPath aapt所在的目录 * @param apkPath   apk的路径。 * @return apkInfo 一个Apk的信息。 */public VersionInfo getApkInfo(String mAaptPath, String apkPath) throws Exception {Process process = mBuilder.command(mAaptPath, "d", "badging", apkPath).start();InputStream is = null;is = process.getInputStream();BufferedReader br = new BufferedReader(new InputStreamReader(is, "utf8"));String tmp = br.readLine();try {if (tmp == null || !tmp.startsWith("package")) {throw new Exception("参数不正确，无法正常解析APK包。输出结果为:\n" + tmp + "...");}VersionInfo info = new VersionInfo();do {setAppProperty(info, tmp);} while ((tmp = br.readLine()) != null);return info;} catch (Exception e) {throw e;} finally {process.destroy();closeIO(is);closeIO(br);}}/** * 设置APK的属性信息。 *  * @param info * @param source */private void setAppProperty(VersionInfo info, String source) {if (source.startsWith(PACKAGE)) {splitPackageInfo(info, source);}if (source.startsWith(APPLICATION_LABEL)) {info.setAppName(getPropertyInQuote(source));}}/** * 返回出格式为name: 'value'中的value内容。 *  * @param source * @return */private String getPropertyInQuote(String source) {int index = source.indexOf("'") + 1;return source.substring(index, source.indexOf('\'', index));}/** * 获取出包名、版本等信息。 *  * @param info * @param packageSource */private void splitPackageInfo(VersionInfo info, String packageSource) {String[] packageInfo = packageSource.split(SPLIT_REGEX);info.setVersionCode(Integer.parseInt(packageInfo[4]));info.setVersionName(packageInfo[6]);}/** * 释放资源。 *  * @param c *  将关闭的资源 */private final void closeIO(Closeable c) {if (c != null) {try {c.close();} catch (IOException e) {e.printStackTrace();}}}}

  

在Spring框架下，需要将aapt.exe文件拷贝到Deployed Resources/webapp路径下，如果实际放置路径为Deployed Resources/webapp/lib/aapt.exe，调用代码如：

VersionInfo versionInfo = new ApkUtil().getApkInfo(request.getSession().getServletContext()                        .getRealPath("/lib/aapt"), apkFilePath);

VersionInfo定义如下：

public class VersionInfo{    /** 版本号 */    private int    versionCode;    /** 版本名称 */    private String versionName;    /** 应用程序名*/    private String appName;            public int getVersionCode(){        return versionCode;    }    public void setVersionCode(int versionCode){        this.versionCode = versionCode;    }    public String getVersionName(){        return versionName;    }    public void setVersionName(String versionName){        this.versionName = versionName;    }    public String getAppName(){        return appName;    }    public void setAppName(String appName){        this.appName = appName;    }}
