apkparser's Introduction

Documentation on GoDoc

ZipReader

Because Android can handle even broken ZIP archives, this packages has it's own zip reader, based on archive/zip.

axml2xml

A tool to extract AndroidManifest.xml and verify APK signature is also part of this repo.

go get github.com/avast/apkparser
go install github.com/avast/apkparser/axml2xml
./axml2xml -v application.apk

Example

package main

import (
	"encoding/xml"
	"fmt"
	"github.com/avast/apkparser"
	"os"
)

func main() {
	enc := xml.NewEncoder(os.Stdout)
	enc.Indent("", "\t")
	zipErr, resErr, manErr := apkparser.ParseApk(os.Args[1], enc)
	if zipErr != nil {
		fmt.Fprintf(os.Stderr, "Failed to open the APK: %s", zipErr.Error())
		os.Exit(1)
		return
	}

	if resErr != nil {
		fmt.Fprintf(os.Stderr, "Failed to parse resources: %s", resErr.Error())
	}
	if manErr != nil {
		fmt.Fprintf(os.Stderr, "Failed to parse AndroidManifest.xml: %s", manErr.Error())
		os.Exit(1)

apkparser's Issues

negative versionCode transferred to uint32

-1 => 4294967295

avast\apkparser\resources.go:423:8: constant 4294967295 overflows int

=> limit := math.MaxInt32

seems work.

Parse apk with given io.Reader

Hello,

i wanted to ask if it is or would be possible to add a feature to parse an apk from an already loaded file.
The idea behind this is to have the file already in memory (e.g. due to reading the body from a http request) and then parse the apk.

file, _ := <get file from somewhere, already in memory, type io.Reader or []byte>
enc := ...

err = apkparser.ParseAPKFromFile(file, enc, nil)
if err != nil {
    log.Println(err)
 }

Take care
