Error=BadAuthentication

[achyut007]

Hi,
I am getting issue while trying to sign in into google account. I have automated script to download the apk files from Google Play store. The script was running fine till last week. But, recently getting following error related to akdeniz.googleplaycrawler library:

Exception in thread "main" com.akdeniz.googleplaycrawler.GooglePlayException: Error=BadAuthentication
at com.akdeniz.googleplaycrawler.GooglePlayAPI.executeHttpRequest(GooglePlayAPI.java:522)
at com.akdeniz.googleplaycrawler.GooglePlayAPI.executePost(GooglePlayAPI.java:482)
at com.akdeniz.googleplaycrawler.GooglePlayAPI.executePost(GooglePlayAPI.java:462)

and so on...
Currently, I am using googleplaycrawler-0.3.jar to download apk files from play store.
How can I resolve it? Can you please help me in this issue?

Thank you,
Achyut

Use auth token for login instead email/password
egirault/googleplay-api#74

When using the authentication token I get the following error in the login step

------------- Login Result -------------
LSID = [BAD_COOKIE]
SID = [BAD_COOKIE]

So I am asking if the code works fine with you. what is the key/value pairs that you used for the cookies.

I used this repo for generate the auth token
https://github.com/yeriomin/token-dispenser

@anton9088 I used the same repo to generate the token. So I have the following questions:

1. the akdeniz's code makes 4 steps (checkin, login, checkin, then login):

- postCheckin
- loginAC2DM
- postCheckin
- login

So can you show a code snippet for the changes that you made to the code (i.e., which step that you bypassed).

Checkin:

   public AndroidCheckinResponse checkin() throws Exception {

	// this first checkin is for generating android-id
	AndroidCheckinResponse checkinResponse = postCheckin(Utils.generateAndroidCheckinRequest(deviceModel, SDK_Version).toByteArray());
	this.setAndroidID(BigInteger.valueOf(checkinResponse.getAndroidId()).toString(16));
	setSecurityToken((BigInteger.valueOf(checkinResponse.getSecurityToken()).toString(16)));

	String c2dmAuth = loginAC2DM();
	
	AndroidCheckinRequest.Builder checkInbuilder = AndroidCheckinRequest.newBuilder(Utils.generateAndroidCheckinRequest(deviceModel, SDK_Version));

	AndroidCheckinRequest build = checkInbuilder.setId(new BigInteger(this.getAndroidID(), 16).longValue())
		.setSecurityToken(new BigInteger(getSecurityToken(), 16).longValue()).addAccountCookie("[" + getEmail() + "]")
		.addAccountCookie(c2dmAuth).build();
	// this is the second checkin to match credentials with android-id
	return postCheckin(build.toByteArray());
    }

Then Login:

    /**
     * Authenticates on server with given email and password and sets
     * authentication token. This token can be used to login instead of using
     * email and password every time.
     */
    public void login() throws Exception {

	HttpEntity responseEntity = executePost(URL_LOGIN, new String[][] { { "Email", this.getEmail() }, { "Passwd", this.password },
		{ "service", "androidmarket" }, { "accountType", ACCOUNT_TYPE_HOSTED_OR_GOOGLE }, { "has_permission", "1" },
		{ "source", "android" }, { "androidId", this.getAndroidID() }, { "app", "com.android.vending" },
		{ "device_country", "us" }, { "lang", "en" }, { "sdk_version", SDK_Version }, }, null);

    	System.out.println("YYYYYYY Step 2: System could login with ID [" + this.getAndroidID() + "]");
	Map<String, String> response = Utils.parseResponse(new String(Utils.readAll(responseEntity.getContent())));
	if (response.containsKey("Auth")) {
	    setToken(response.get("Auth"));
	} else {
	    throw new GooglePlayException("Authentication failed!");
	}
    }

2. The token-dispenser project has two token generation methods. Did you bypass the two checkin steps and used the checkin token and used the general token for the long step?

I simply use GooglePlayAPI.login(String token) method
