Deferred login on android doesn't catch intent-filter callback

[Ruslan-Mz]

Hello!

Can you please check if this is a bug on RN side, or maybe on Android SDK side? Or maybe there's just something missing in the configuration?

I've created an app from this template https://github.com/forcedotcom/SalesforceMobileSDK-Templates/tree/dev/ReactNativeDeferredTemplate
Uncommented login activity and intent-filter for it:
AndroidManifest.xml:

        <activity android:name="com.salesforce.androidsdk.ui.LoginActivity"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"
            android:launchMode="singleInstance"
            android:exported="true">

            <intent-filter>
                <data android:scheme="testsfdc"
                    android:host="*"
                    android:path="/mobilesdk/detect/oauth/done" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

I haven't changed any callbacks or hosts - logging in to sandbok test.salesforce.com with our test user
Login succeeds, but I'm returned on main page without getting login callback, the page still have a button "Login"

app.js:

onLogin() {
        console.log("onLogin called");
        oauth.authenticate(
            (data) => { <———————- NOT CALLED!
                console.log("login completed ", data);
                this.fetchData(data)
            },
            (error) => {console.log('login failed:' + error)}
        );        
    }

I've cheked intent filters, documentation, have put some logs in the LoginActivity in the SDK to see if it's called, and I see that method "finish" is called, but new intent is not.

If I press "Login" button on main page again - then I'm authenticated without opening web view and I receive the data. Button on main page changes to "Logout" as expected.

In case I disable deferred login, everything works on first attempt - I'm logged in on return from web view and I dont need to press login again.

The issue is that without callback on first login attempt it's not clear if user is logged in or no. LoginActivity just closes.

Found out that it's because of the already reported bug: #247
