node-apk

Node APK

A library to parse Android application's manifest and signature

Installation

This library is meant to work with Node JS 4 or later. You can install it using npm:

npm install node-apk

The use of typescript is highly recommended for which this library has full typing support.

Usage

Import the Apk class and instantiate it passing your APK's file path

import {Apk} from "node-apk"; const apk = new Apk("yourapplication.apk");

Manifest information

Application manifest details can be accessed using:

apk.getManifestInfo().then((manifest) => { console.log(`package = ${manifest.package}`); console.log(`versionCode = ${manifest.versionCode}`); console.log(`versionName = ${manifest.versionName}`); // for properties which haven't any existing accessors you can use the raw binary xml console.log(JSON.stringify(manifest.raw, null, 4)); });

Certificate information

Certificates can be retrieved like the following:

apk.getCertificateInfo().then((certs) => certs.foreach((cert) => { console.log(`issuer = ${cert.issuer.get("CN")}`); console.log(`subject = ${cert.subject.get("CN")}`); console.log(`validUntil = ${cert.validUntil}`); console.log(cert.bytes.toString("base64")); }));

Application resources

Application resources can be resolved as shown below:

const iconBytes = Promise.all<Manifest, Resources>([apk.getManifestInfo(), apk.getResources()]) .then(([manifest, resources])) => { let label = manifest.applicationLabel; if (typeof label !== "string") { const all = resources.resolve(label); label = (all.find((res) => (res.locale && res.locale.language === "fr")) || all[0]).value; } console.log(`label = ${label}`); // resolve and extract the first application icon found return apk.extract(resources.resolve(manifest.applicationIcon)[0]); }

Cleaning up

Once you are done, don't forget to release you Apk object:

apk.close();
