Android - OAuth Callback URL issue for a handful of devices

benherbert · September 26, 2023, 2:12pm

Hi there, community!

We have just started to experience an issue with our app in the last 2-3 weeks.

Our app is a ReactJS SPA PWA turned Capacitor Hybrid App.

The issue is as follows:

Open app and be automatically redirected to our log in page (OAuth 2.0 journey)
Log In with user details
Be automatically redirected back to the app.
Normally the user now has a valid session and can begin using the app.
However, in this bug, this does not happen. Instead, when the user is taken back to the app, they are not taken to the correct page and OAuth is not completed correctly.

Points to note:-

We can only replicate the issue on 4 Android devices.
So far, it is not an issue on iOS or Web.
We cannot replicate it in an emulator (Android Studio).
We have tested around a dozen physical devices and they can also not replicate the bug.
All the Android devices we have tested are on the latest version (13 + any patches, etc.).
All devices prefer Google Chrome as their browser and are on the latest version 117 (+ any patches, etc.).
It makes no difference what account type or subscription type the user has.

The devices the bug occurs in are:-

Samsung S20 FE
Motorola Edge 30 Neo
Motorola Moto 3 (although that had an older Android version installed)

It was working fine for these people a couple of weeks ago!

Other Info:-

Capacitor 5
Gradle 8
Target SDK 33

Many thanks in advance for your thoughts and idea everyone!

I have an update that may be worth recording.

We have connected one of the problematic devices to Android Studio for debugging.

I’ve provided the logs below. Noteworthy items include [object DOMException].

The number of Android devices experiencing blank screen is increase by the day. Eek!

Hello @benherbert,

I am also having problems with OAuth 2 on some Android Devices.
Some Android Users are always getting logged out after they close the app.
It seems like the Cookies aren’t stored correctly.

Do you also use cookies to store the Tokens?
Which OAuth Provider are you using?
Which OIDC Library do you use?

Kind Regards,
Marius

benherbert · October 4, 2023, 8:05am

Our problems could be related - even though your symptoms are different from mine. I hope I can help!

After some debugging - it looks like our app is crashing when it “Resumes” after opening Chrome (Child Browser / Capacitor Browser API) to authenticate, due to an on-device memory issue.

I plan to provide a full update today once I have confirmed the above. I discovered this information on this specific issue in CapacitorJS docs here: App | Capacitor Documentation

We are using our own Public API (Crunch Accounting API https://developer.crunch.co.uk/). Which is OAuth 2.0 with PKCE, and HTTP Only Cookies.

Our app is ReactJS and we just “store” the tokens in the React-Query cache. It’s a very simple set up - no additional packages (apart from pkce-challenge).

Because I am not using client side cookies, I haven’t experienced the exact issue you are describing, but have you looked at the Capacitor Cookies API? Capacitor Cookies Plugin API | Capacitor Documentation

Thanks for reaching out, and good luck!

Hi @benherbert,

thank you for the prompt response!

I also noticed that my app crashes on some devices after Chrome was opened, and the app was paused. This could result in a loss of the stored keys.

Currently, I am using an OIDC Library for Angular with a Custom Storage Factory because the Library is using Session Storage which will always get lost after the app gets closed. I couldn’t use @capacitor/preferences or Secure Storage because it’s async and the OIDC Library only supports synchronous methods. So I used Cookie.js which gets patched by Capacitor. More Information here: Allow asynchronous custom OAuthStorage implementations · Issue #943 · manfredsteyer/angular-oauth2-oidc · GitHub

So in my case, it’s either a cookie problem or the crash of the app as soon as it enters background mode. I already updated the App to Capacitor 5, and I am currently trying to add a fallback if cookies aren’t working.

I also found out that the OneSignal Plugin crashes my app. Very strange.

Please keep me updated with your results!

Kind Regards,
Marius

benherbert · October 4, 2023, 8:48am

Hi @mariusbolik !

Perhaps you can rule out “background crashing” with some code like this:-

Sorry that its in ReactJS and not Angular - I am not familiar with Angular component lifecycles - but interested to know!

import { Browser } from '@capacitor/browser'
import { App } from '@capacitor/app'
// and your other imports...

// And the rest of your app... 🤣
const [debugInfo, setDebugInfo] = useState('')

// Somewhere in the component...
useEffect(() => {
  setDebugInfo('I just swallowed my gum!')
}, [])

// One of these two listeners may help...
Browser.addListener('browserFinished', () => {
  console.log('Browser exited')
  setDebugInfo('browser exited')
})

App.addListener('appRestoredResult', (data) => {
  console.log('Restored state:', data)
  setDebugInfo('Restored state')
})

return (
  // Rest of the component...
  {debugInfo && <p>{debugInfo}</p>}
)

It should be nice to be able to rule this one out and then look at Cookies!

Good luck!

Solved the bug this week!

It was regarding the protocol / schema and hostname I had chosen for the app.

These are set in the capacitor.config.ts file and the documentation can be found here: Capacitor Configuration | Capacitor Documentation. The default hostname is localhost; and the default schema is capacitor on iOS and http on Android.

For simplicity, I customised these to capacitor://localhost for both iOS and Android. It has been that way since the app was launched in April 2023 and worked perfectly fine.

Approximately 4 weeks ago, Android was no longer cool with this! I am still looking into the facts of the matter, so if anyone knows the reason for this, please let me know.

I have now set the schema for Android to https which satisfies both Android and our Public API.

You cannot use https/http on iOS because it “Can’t be set to schemes that the WKWebView already handles” (Capacitor Configuration | Capacitor Documentation).

The error manifested in a Redux Saga performing a history push, reporting as DOM Exception, Failed to execute 'pushState' on 'History': A history state object with URL [...] cannot be created in a document with origin [...] and URL [...].

There was a knock on effect from making this change regarding Deep Links: Android preferred me to use the App ID (e.g. com.app.my) for linking from the browser to the app. With the former, Chrome kept asking how the user would prefer to open the URL (i.e. with the app or Chrome, and “just once” or “every time”).

Thus, I now use Capacitor Device API (Device Capacitor Plugin API | Capacitor Documentation) as needed in my app to handle the differences.

When I find out the root cause, I will update this thread.

Thanks and happy coding!
