java.lang.ClassNotFoundException: com.firebase.ui.auth.data.model.FlowParameters #1416

Step 1:

When trying to get the Auth UI going:

        Intent intent = AuthUI.getInstance()
                    .createSignInIntentBuilder()
                    .setTheme(R.style.SplashTheme)
                    .setAvailableProviders(idpConfigs)
                    .setTosAndPrivacyPolicyUrls(getString(R.string.terms_url), getString(R.string.privacy_url))
                    .setIsSmartLockEnabled(!BuildConfig.DEBUG)
                    .build();
        startActivityForResult(intent, RC_FIREBASE_UI_SIGNIN);

I see the following behaviour:

if idpConfigs contains exactly one item, it correctly proceeds to the one login method
if idpConfigs contains more than one item, the AuthMethodPickerActivity is displayed WITHOUT any of the login buttons (but it correctly shows the ToS/PP at the bottom)

Looking through the logs, I see this error:

Which would explain the issue. Here's the relevant snippet of my build.gradle:

    // Play Services
    implementation "com.google.android.gms:play-services-auth:15.0.1"
    implementation "com.google.android.gms:play-services-base:15.0.1"
    implementation "com.google.android.gms:play-services-appinvite:15.0.1"
    implementation "com.google.android.gms:play-services-gcm:15.0.1"
    implementation "com.google.android.gms:play-services-location:15.0.1"
    implementation "com.google.android.gms:play-services-places:15.0.1"
    implementation "com.google.android.gms:play-services-ads:15.0.1"

    // Firebase
    implementation "com.google.firebase:firebase-core:16.0.0"
    implementation "com.google.firebase:firebase-auth:16.0.1"
    implementation "com.google.firebase:firebase-database:16.0.1"
    implementation "com.google.firebase:firebase-storage:16.0.1"
    implementation "com.google.firebase:firebase-crash:16.0.1"
    implementation "com.google.firebase:firebase-messaging:17.3.0"
    implementation "com.google.firebase:firebase-config:16.0.0"

    implementation "com.google.firebase:firebase-perf:16.1.0"
    implementation 'com.firebaseui:firebase-ui:4.1.0'

This used to work, but I guess it broke with a recent update of FirebaseUI.

Step 2: Describe your environment

Android device: S9+
Android OS version: 8.0.0
Google Play Services version: 12.8.74
Firebase/Play Services SDK version: 15.0.1
FirebaseUI version: 4.1.0

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

dimipaun · 2018-09-13T18:38:02Z

I just updated to Firebase UI 4.2 and I'm getting the same error.

samtstern · 2018-09-13T20:11:55Z

@dimipaun are you seeing this in both debug an production builds? Are you using ProGuard or R8 in either?

dimipaun · 2018-09-14T16:34:42Z

Yes, I see them in both. And yes, we use ProGuard in both. I don't know about R8 though, how can I tell? I don't remember doing anything to enable it explicitly.

samtstern · 2018-09-14T16:58:06Z

Ah ok. Can you do two things for me then?

Show me your ProGuard configuration.
Try running a debug build with ProGuard turned off and see if you can still see this issue.

dimipaun · 2018-09-14T21:34:55Z

And I double checked, my bad -- we do NOT use ProGuard in debug builds.

SUPERCILEX · 2018-09-17T04:03:41Z

Looks like we need to manually set our class loader (that would make sense since flow params won't be in the boot class loader):

FirebaseUI-Android/auth/src/main/java/com/firebase/ui/auth/data/model/FlowParameters.java

Line 87 in a045fb9

return intent.getParcelableExtra(ExtraConstants.FLOW_PARAMS);

dimipaun · 2018-09-17T18:58:54Z

Thanks @SUPERCILEX! So I guess this has to happen on the Firebase UI side - any thoughts on ETA?
Anything I can do to help?

SUPERCILEX · 2018-09-18T03:27:19Z

Absolutely! From what I understand, you basically want to add this to the line I linked to above: setExtrasClassLoader(AuthUI.class.getClassLoader()).

Do you feel up to submitting a PR? TBH, there's no way of checking if it actually works until you ship it, so as long as that line doesn't break stuff, SGTM. 👍

See https://stackoverflow.com/a/28589962/4548500 for details.

samtstern · 2018-09-20T16:16:37Z

@dimipaun can you help us try to reproduce the issue? Would help to know:

Device type and Android OS version
What code you're running to cause it
How often this happens

It's totally crazy to me that you're the only one reporting this issue! For something as basic as this I'd expect everyone to be yelling :-/

dimipaun · 2018-09-20T16:20:01Z

Yes, of course!

Samsung S9+ w/ Android 8.0.0
Firebase UI 4.2.1-SNAPSHOT
It happens ALL the time, both in devel (w/o ProGuard) and prod (w/ ProGuard)
The code is pretty vanilla:

        List<AuthUI.IdpConfig> idpConfigs = new ArrayList<>();
        for (ClientInfo.LoginMethod method: methods) {
            switch (method) {
                case FACEBOOK:
                    if (AppUtil.isFacebookMisconfigured(getContext())) {
                        Salute.warn(getContext(), "Facebook Sign-in is misconfigured", Toast.LENGTH_LONG).show();
                    } else {
                        idpConfigs.add(new AuthUI.IdpConfig
                                .FacebookBuilder()
                                .setPermissions(Arrays.asList("default", "email"))

                                .GoogleBuilder()
                                .setScopes(Arrays.asList("profile", "email"))
                                .build());
                    }
                    break;

                    .setTosAndPrivacyPolicyUrls(getString(R.string.terms_url), getString(R.string.privacy_url))
                    .setIsSmartLockEnabled(!BuildConfig.DEBUG)
                    .build();
startActivityForResult(intent, RC_FIREBASE_UI_SIGNIN);

Note, if there's only one element in the idpConfigs array, it works as it goes directly to that provider.

Dang! 😞 Can you reproduce it on an emulator or a non Samsung device? Or is it just that device?

Hmmm, same stacktrace, I wonder if I'm using the latest changes....

samtstern · 2018-09-21T17:25:26Z

@dimipaun if you want to be triple sure:

Check out the dev branch of FirebaseUI
Change the version in Config.kt to something like 5.6.7-SNAPSHOT
Run ./gradlew clean :library:prepareArtifacts :library:publishAllToMavenLocal
In your app, add mavenLocal() to your repositories {} block
Depend on the version you made up

Then you can't be possibly running old code!

dimipaun · 2018-10-01T15:06:05Z

Hi @samtstern @SUPERCILEX on closer inspection, the code doesn't reach our activity, look at the stacktrace:

Caused by: java.lang.ClassNotFoundException: com.firebase.ui.auth.data.model.FlowParameters
        at java.lang.Class.classForName(Native Method)
        at java.lang.BootClassLoader.findClass(ClassLoader.java:1355)

        at android.os.Binder.execTransact(Binder.java:682)

so whatever we add in:

public static FlowParameters fromIntent(Intent intent) {
        //this is required to fix #1416 - ClassNotFound for FlowParameters
        intent.setExtrasClassLoader(AuthUI.class.getClassLoader());
        return intent.getParcelableExtra(ExtraConstants.FLOW_PARAMS);
    }

will not work, right? Am I missing something?

Would it make sense to setExtrasClassLoader in HelperActivityBase where we create the intent? Right now we have:

        return new Intent(
                checkNotNull(context, "context cannot be null"),
                checkNotNull(target, "target activity cannot be null"))
                .putExtra(ExtraConstants.FLOW_PARAMS,
                        checkNotNull(flowParams, "flowParams cannot be null"));
                .putExtra(ExtraConstants.FLOW_BUNDLE,
                        checkNotNull(flowParams, "flowParams cannot be null").toBundle());
    }

maybe we do:

        Intent intent = new Intent(
                checkNotNull(context, "context cannot be null"),
                checkNotNull(target, "target activity cannot be null"))
                .putExtra(ExtraConstants.FLOW_PARAMS,
                        checkNotNull(flowParams, "flowParams cannot be null"));
                .putExtra(ExtraConstants.FLOW_BUNDLE,
                        checkNotNull(flowParams, "flowParams cannot be null").toBundle());

        intent.setExtrasClassLoader(AuthUI.class.getClassLoader());
        return intent;
    }

Thoughts?

SUPERCILEX · 2018-10-01T15:40:58Z

Go for it! 👍 Though it would be nice if you could test it locally first. 😊

dimipaun · 2018-10-01T16:36:42Z

I'd love to test locally, but frankly I haven't figured out how to build it and then use in the app.

SUPERCILEX · 2018-10-01T16:40:46Z

Where are you getting stuck? What error?

This is because the exception happens _before_ we get to read the FlowParameters from the extras/bundle.
