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:
``

shell
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

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

Application manifest details can be accessed using:

javascript
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));
});

Certificates can be retrieved like the following:

javascript
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 can be resolved as shown below:

javascript
const iconBytes = Promise.all([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]); }`

`$3`


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

javascript
apk.close();
