Lock.Android: IllegalStateException in GoogleIdentityProvider.onPermissionsRequireExplanation

Hi,

We upgraded to 1.17.0 and are having a major problem with the native Google authentication. We thought we were using the textbook integration :

// setup Auth0 and the native Google integration
ParameterBuilder paramsBuilder = ParameterBuilder.newBuilder();
String scope = ParameterBuilder.SCOPE_OFFLINE_ACCESS + " email";
Map<String, Object> parameters = paramsBuilder.setScope(scope).asDictionary();

LockContext.configureLock(
        new Lock.Builder()
                .loadFromApplication(this)
                .withIdentityProvider(Strategies.GooglePlus, new GoogleIdentityProvider(this))
                .authenticationParameters(parameters)
);

When a user uses the Google authentication button, the native integration correctly asks for permission to access the contacts, then if the user cancels that request, all future use of the Google auth button will crash the app with this stacktrace :

This is on a Nexus 5, Android 6.0.1, in an app with these settings :

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 23
...

Gradle : 2.14.1 Android Plugin : com.android.tools.build:gradle:2.1.3

Debugging a little bit this issue, as the AppCompat dialog builder is using the context from the application, it’s true that there is no theme. But the issue should not be there, as we got the code from the Auth0 sample code which also uses the application instance to build the GoogleIdentityProvider.

Happy to provide more info if needed. Thanks.
