Autofill does not work anymore (reports false for afm.isEnabled()) and can not be enabled again with an afm.requestAutofill() if one attaches a new Base Context with context.createConfigurationContext(configuration) as shown below:

public class MainActivity extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);

                AutofillManager afm = this.getSystemService(AutofillManager.class);
               
                Log.d("AARN", "HasEnabledAutofillService: " + (afm.hasEnabledAutofillServices() ? "true" : "false"));
                Log.d("AARN", "isAutofillSupported: " + (afm.isAutofillSupported() ? "true" : "false"));
                Log.d("AARN", "isEnabled: " + (afm.isEnabled() ? "true" : "false"));

                // This Log.d reports:

                // when using updateConfiguration()
                // D/AARN: HasEnabledAutofillService: false
                // D/AARN: isAutofillSupported: true
                // D/AARN: isEnabled: TRUE !!

                // for the not working createConfigurationContext()
                // D/AARN: HasEnabledAutofillService: false
                // D/AARN: isAutofillSupported: true
                // D/AARN: isEnabled: FALSE !!
        }

        @Override
        protected void attachBaseContext(Context newBase) {
                Context localContext = applyLocale(newBase, "en");
                super.attachBaseContext(localContext);
        }

        private Context applyLocale(final Context context, final String language) {
                Resources resources = context.getResources();
                Configuration configuration = resources.getConfiguration();
                configuration.setLocale(new Locale(language));

                // this breaks autofill
                return context.createConfigurationContext(configuration);

                // this deprecated method works and DOES NOT break autofill
                //resources.updateConfiguration(configuration, resources.getDisplayMetrics());
                //return context;
        }
}


What you think the correct behavior should be:
using the context.createConfigurationContext() should not disable autofill. Or it should be possible to enable autofill again with afm.requestAutofill()

Don't forget to mention which version of Android you're using, and/or which
device the problem appears on (model and Android version):
Googel Pixel phone running Android 8.0.0 (security patch level Oct 5. 2017)
Build number: OPR3.170623.008
