error 'Unable to load class named [io.jsonwebtoken.impl.DefaultJwtParser]' #10

JunjaK · 2019-12-20T07:14:26Z

Is it a security issue?

May be no...

What happened actually?

Actually, in flutter debug mode, It works well. but when I install my flutter app in my device with release mode of flutter, Gets error like this.

PlatformException(INTERNAL_ERROR, java.io.IOException: org.json.JSONException: Unable to load class named [io.jsonwebtoken.impl.DefaultJwtParser] from the thread context, current, or system/application ClassLoaders.  All heuristics have been exhausted.  Class could not be found.

Authorization menu works well like this.

How can I solve this problem??
(I already tried this issue. line/line-sdk-android#7, may be nothing to do with this issue... )

my proguard code is

-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }

Your environment?

in release mode
Android 9.0
Galaxy s10e(SM-G970N)
in debug mode
emulator pixel2 and, 3, Andorid sdk version 28, Window10

The text was updated successfully, but these errors were encountered:

onevcat · 2019-12-20T07:18:25Z

I guess it is related to some pro guard rules. @plateaukao Can you look at it when you have time?

JunjaK · 2019-12-20T08:35:18Z

May be It concerned with scope of 'openid' ( json web token )
When I run line sign in with no scope, It works well.
But when I run line sign in with scope ["profile", "openid", "email"], turns out error like above.

However I applied openid in line developer.
So I don't know how to solve this problem ..

(This case also release mode, debug mode works well everything.)

plateaukao · 2019-12-24T04:19:33Z

Hi, @JunjaK
The fix is under review now. #11
Hope the pull request can fix the proguard issue in release version.

JunjaK · 2019-12-24T07:39:20Z

Thanks for your help.
I'll check if new version of line sdk is released on pub.dev.

onevcat · 2019-12-25T04:15:35Z

Version 1.2.3 was released for this issue. Thank you for reporting!

JunjaK · 2019-12-25T18:43:23Z

Thanks!!
It works well.
But there is still something to ask,
There is difference between debug mode data and release mode data (result of line social login)
In debug mode, the result data of line social login is same as this repository's doc.
But in release mode, the result data of line social login is something different.
(This issue also applies to previous versions. 1.2.1(I only tested this version))
Example is like this.

{
 b: 
  {
    access_token: raw string of access token(private), 
    expires_in: 2592000000, 
    id_token: 
      {
        "a": raw string of id token(private), 
        "b": "https://access.line.me",
        "c":  some token(private),
        "d": audience(private) ,
        "e":"Dec 26, 2019 4:18:50 AM",
        "f":"Dec 26, 2019 3:18:50 AM",
        "h": some token(private),
        "i":["lineautologin"], 
        "j":"윤준현(じゅん jun)", 
        "k": profile url(private)
        "m" : email string(private)
      }, 
    }
  c: "profile openid" 
}

Some '(private)' texts are string that leaks my information. so I can't paste it here.
Anyway, in release mode, I can't access result.userprofile, result.acesstoken. I can only access data above in debug mode.

This is just report of the result.
It really works well after update 1.2.3 version.
I just want report data differences between release mode and debug mode

onevcat · 2019-12-26T04:59:07Z

I think this should be finally fixed in 1.2.4.

JunjaK · 2019-12-26T09:24:33Z

What happened actually?

After I Updated line sdk 1.2.4, I got error.
These are errors when I run code 'flutter build appbundle' same as release mode.
In debug mode, Everything is okay.

plateaukao · 2019-12-26T09:51:24Z

@JunjaK do you use AndroidX for your flutter android project?

Currently, line-sdk-android and also flutter_line_sdk still uses android support library instead of AndroidX library.

Could you let me know your flutter development environment?

I tried to migrate the plugin to androidx library.

Could you help to try out this pull request? #13

JunjaK · 2019-12-26T12:36:25Z

@plateaukao
Okay.
What exactly should I do to complete pull request #13 ?

I am using AndroidX in my flutter project and
the result of flutter doctor is this

$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel beta, v1.12.13+hotfix.6, on Microsoft Windows [Version 10.0.18363.535], locale    ko-KR)

[√] Android toolchain - develop for Android devices (Android SDK version 29.0.2)
[√] Android Studio (version 3.5)
[√] VS Code (version 1.41.1)

and
my pubspec.ymal is this

name: nuwbies_event
description: A new Flutter project.

environment:
  sdk: ">=2.1.0 <3.0.0"

  flutter:
    sdk: flutter
  flutter_line_sdk: ^1.2.4
  
dev_dependencies:
  flutter_test:
    sdk: flutter

module:
  androidX: true

Is there anything else I need to tell you?
Because I'm newbie of flutter, so I don't know much of flutter.

Plus, There is something to correct.
The same error occurs in debug mode.

I updated a new pull request to remove the failed fix, and still tried to fix the wrong idToken json data in pull request #15.

If possible, please help to fetch pull request #15 , and modify your pubspec.yaml to something similar to following snippet, and try to build your flutter app in release mode again.

...
dependencies:
  flutter:
    sdk: flutter
  #flutter_line_sdk: ^1.2.4
  
dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_line_sdk:
    path: ../   # <-- change to where you put the flutter_line_sdk project locally

...

JunjaK · 2019-12-27T07:46:32Z

It works well both in release mode and in debug mode
Thanks.
The Line login data in release mode also same as in debug mode.
