Integration into existing Android Client - User canceled the auth error

[dpogoda]

Hi, I've integrated my react-native app including the react-native-auth0 library into an existing Android project following this tutorial https://facebook.github.io/react-native/docs/integration-with-existing-apps.html.

The integration worked almost perfectly. But when I try to login, the custom tab intent starts and after a short while I get redirected to my login screen and I get the following error
{"error": "a0.session.user_cancelled", "error_description": "User cancelled the Auth"}.

When I check the auth0 dashboard at www.auth0.com , I can see that the login was actually successful. So there must be a redirection error. The callback URL is correct.

I followed the react-native-auth0 guide and applied launchMode="singleTask" to the respective activity etc. Also I tried different versions of chromeTabs.

The thing is that the login part works perfectly in my stand-alone react-native project. My instinct says that it has to do something with the gradle config. On the other hand I tried different versions, downgraded the project to 23.0.1 etc.

I'm using react-native-auth0 1.2.1 react-native 0.50.3 and I don't know if it is important react-native-router-flux 4.0.0-beta.24

My ReactActivity in the AndroidManifest.xml is configured as follows:

        <activity
            android:name=".alightversion.ReactCreateEventActivity"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"
            android:launchMode="singleTask"
            android:label="@string/app_name"
            android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
            android:windowSoftInputMode="adjustResize"
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data
                    android:host="XXX" <!-- I hid the correct host for this post -->
                    android:pathPrefix="/android/${applicationId}/callback"
                    android:scheme="${applicationId}" />
            </intent-filter>
        </activity>

This is my build.gradle (Module: app)

Could be related to this issue https://github.com/auth0/react-native-auth0/issues/83

[dpogoda]

I could fix the problem. I had to add to the following code into my activity class:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    mReactInstanceManager.onNewIntent(intent);
}

I am seeing this same issue. ~Would an improper Callback URL result in this? The instructions are a little confusing on what to use. I took this word for word:~

~{YOUR_APP_PACKAGE_NAME}://YOUR_AUTH0_DOMAIN/android/{YOUR_APP_PACKAGE_NAME}/callback~ ~And didn't add an http or https identifier as I'm not sure where it's supposed to go?~

Edit: Disregard that, I just tried changing the Callback URL and realized it results in a totally separate error.

Final Edit: Realized that my android:launchMode="singleTask" was in the wrong header section. Looking at the Manifest pointed above, it looks like you don't have that issue. Sorry I couldn't be of more help.

@pythoneer I can confirm that PR #93 does not appear to be the fix for this case.

[cocojoe]

Is this still an issue?

[davrosull]

I'm currently experiencing the same issue. I've got android:launchMode="singleTask" set on my manifest.

The callback URL seems to be triggering - i.e. it returns from the CustomTab. But it doesn't seem to be picking up the actual callback function and instead shows the same error as above

{"error": "a0.session.user_cancelled",
"error_description": "User cancelled the Auth"}

[davrosull]

Following up - if I remove android:launchMode="singleTask" from the manifest, and use Linking.getInitialURL() I can see that the callback URL is being correctly triggered and returns the code parameter.

Has anyone managed to get this working?

RNAuth0 1.3.0 RNNavigation 2.0.2538

Edit: Managed to get this working! I mistakenly had android:launchMode="singleTask" under <application> and not <activity>.

[IndianAg0711]

@kevinranks did the same, ty!

[lbalmaceda]

Just FYI, redirection in android might not work when this SDK is used along the RN Navigation library. This is due to how the deep links work on react-native.

@lbalmaceda any ideas on how to get it to work when using React Navigation? I am running into this issue currently and have not been able to find a solution

[mweel1]

Same here, can we re-open this issue and get it figured out?
