Apk parser with java, for decoding xml file and getting meta infos from apk file.

Features

• Retrieve basic apk metas, such as title, icon, package name, version, etc.
• Parse and convert binary xml file to text
• Classes from dex file
• Get certificate metas and verify apk signature

Get apk-parser

Apk-parser has been submited to maven central repo, maven, gradle, ivy and other build tools can be used to get this lib. With maven, you can add apk-parser as dependency by:

<dependency>
    <groupId>net.dongliu</groupId>
    <artifactId>apk-parser</artifactId>
    <version>2.1.7</version>
</dependency>

From version 2.0, apk-parser requires java7. The last version support java6 is 1.7.4.

Usage

The easiest way is to use the ApkParser class, which contains convenient methods to get AndroidManifest.xml, apk meta infos, etc. #####1. Apk meta info ApkMeta contains name(label), packageName, version, sdk, used features, etc.

try(ApkParser apkParser = new ApkParser(new File(filePath))) {
    System.out.println(apkMeta.getLabel());
    System.out.println(apkMeta.getPackageName());
    System.out.println(apkMeta.getVersionCode());
    for (UseFeature feature : apkMeta.getUsesFeatures()) {
        System.out.println(feature.getName());
    }
}

#####2. Get binary xml and manifest xml file

try(ApkParser apkParser = new ApkParser(new File(filePath))) {
    String manifestXml = apkParser.getManifestXml();
    String xml = apkParser.transBinaryXml("res/menu/main.xml");
}

#####3. Get dex classes

try(ApkParser apkParser = new ApkParser(new File(filePath))) {
    DexClass[] classes = apkParser.getDexClasses();
    for (DexClass dexClass : classes) {
        System.out.println(dexClass);
    }
}

#####4. Get certificate and verify apk signature

try(ApkParser apkParser = new ApkParser(new File(filePath))) {
    ApkSignStatus signStatus = apkParser.verifyApk();
    List<CertificateMeta> certs = apkParser.getCertificateMetas();
    for (CertificateMeta certificateMeta : certs) {
        System.out.println(certificateMeta.getSignAlgorithm());
    }
}

#####5. Locales Apk may appear different infos(title, icon, etc.) for different region and language, which is determined by Locales. If locale is not set, the "en_US" locale(Locale.US) is used. You can set locale like this:

try(ApkParser apkParser = new ApkParser(new File(filePath))) {
    apkParser.setPreferredLocale(Locale.SIMPLIFIED_CHINESE);
    ApkMeta apkMeta = apkParser.getApkMeta();
}

The PreferredLocale parameter work for getApkMeta, getManifestXml, and other binary xmls. Apk parser will find best match languages with locale you specified.

If locale is set to null, ApkParser will not translate resource tag, just give the resource id. For example, apk title will be '@string/app_name' instead of 'WeChat'.
