Firebaseui-android: Pressing Back button crashes app when on SignInIntentBuilder page

[ryandailey100]

Whenever I press the back button on the SignInIntentBuilder activity, the app just crashes. How can this be fixed? Here is a picture of my code.

Another thing to note is that the highlighted text never gets called:

@ryandailey100 we need more information to assist you such as what version of FirebaseUI you are using and a crash log. You can got the logcat monitor in Android Studio to find the crash logs.

Here is the crash log:

Oh duh!!! The number of times that's happen to me since converting my app to Kotlin, it should have been the first thing I looked at, sorry! ☺️ Just mark the data intent as @Nullable by adding a ? after the Intent type declaration. So it should look like so: data: Intent?.

[ryandailey100]

Perfect that did the trick! Thanks so much 👍

What if its in java ?

[Kurt29]

@ravich528798 If you are using Java, it is probably something different. You should provide more information, maybe create a new issue with logs and stuff

[ravich528798]

`if (firebaseAuth.getCurrentUser() != null) {

        startActivity(new Intent(Login.this, MainActivity.class));

    } else {


        List<AuthUI.IdpConfig> providers = Arrays.asList(
                new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
                new AuthUI.IdpConfig.Builder(AuthUI.PHONE_VERIFICATION_PROVIDER).build(),
                new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build());

        startActivityForResult(
                AuthUI.getInstance()
                        .createSignInIntentBuilder()
                        .setIsSmartLockEnabled(false)
                        .setTheme(R.style.GreenTheme)
                        .setTosUrl("https://termsfeed.com/blog/terms-conditions-mobile-apps/")
                        .setPrivacyPolicyUrl("https://superapp.example.com/privacy-policy.html")
                        .setAvailableProviders(providers)
                        .build(),
                RC_SIGN_IN);
    }`

this is my code which starts intent. When I press back button it goes to an empty intent

[abhaybansod007]

public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (resultCode !== Activity.RESULT_CANCELED) {

       // write code here , using data Intent 
       //Like set Image in ImageView
        }
}

Try this One It's Working for me "data: Intent?"
