package main

import (
   "fmt"
   "time"
   gp "github.com/89z/googleplay"
)

func main() {
   tok, err := gp.NewToken("EMAIL", "PASSWORD")
   if err != nil {
      panic(err)
   }
   auth, err := tok.Auth()
   if err != nil {
      panic(err)
   }
   dev, err := gp.NewDevice(gp.DefaultCheckin)
   if err != nil {
      panic(err)
   }
   auth.Upload(dev, gp.DefaultConfig)
   time.Sleep(gp.Sleep)
   del, err := auth.Delivery(dev, "com.google.android.youtube", 1524094400)
   if err != nil {
      panic(err)
   }
   fmt.Printf("%+v\n", del)

How to get Android JA3?

First install:

https://github.com/emanuele-f/PCAPdroid

Start app, then change from HTTP Server to PCAP File. Then click start, if prompted to save, choose Downloads. Start Android Chrome and wait for a page to load. Then stop monitoring, and copy file to computer:

adb ls /sdcard/Download
adb pull /sdcard/Download/PCAPdroid_22_Oct_15_19_28.pcap

Then my other package can get you the rest of the way:

How to get Android public key?

Get this:

https://apkpure.com/google-play-services/com.google.android.gms

Then extract:

apktool d com.google.android.gms.apk

The Android public key modulus length should always be 128, which Base64 encoded looks like:

AAAAgA

So you should be able to search the extracted files for one of these:

AAAAg
public key available

Result:

smali\gnt.smali
320: const-string v1, "no public key available, using default"
321-
322- invoke-interface {v0, v1}, Lalyp;->u(Ljava/lang/String;)V
323-
324- const-string v0, "AAAAgMom/1a/v0lblO2Ubrt60J2gcuXSljGFQXgcyZWveWLEwo6prwg...

Types

type AppDetails

type AppDetails struct {
	DeveloperName    string   `json:"1"`
	VersionCode      int      `json:"3"`
	Version          string   `json:"4"`
	InstallationSize int      `json:"9"`
	Permission       []string `json:"10"`
}

type Auth

type Auth struct {
	url.Values
}

func (Auth) Delivery

func (a Auth) Delivery(dev *Device, app string, ver int) (protobuf.Decoder, error)

func (Auth) Details

func (a Auth) Details(dev *Device, app string) (*AppDetails, error)

func (Auth) Upload

func (a Auth) Upload(dev *Device, con Config) error

This seems to return `StatusOK`, even with invalid requests, and the response body only contains a token, that doesnt seem to indicate success or failure. Only way I know to check, it to try the `deviceID` with a `details` request or similar. Also, after the POST, you need to wait at least 16 seconds before the `deviceID` can be used.

type Checkin

type Checkin struct {
	Checkin struct{} `json:"checkin"`
	Version int      `json:"version"`
}

type Config
