getCurrentActivity().get() is null when requesting permission

Android

Here’s one of many stack traces from Google Play Console:

JNI DETECTED ERROR IN APPLICATION: obj == null

Here’s my current version of juce’s FragmentOverlay::open:

734 void FragmentOverlay::open()
735 {
736     auto* env = getEnv();
737
738     LocalRef<jobject> bundle (env->NewObject (AndroidBundle, AndroidBundle.constructor));
739     env->CallVoidMethod (bundle.get(), AndroidBundle.putLong, javaString ("cppThis").get(), (jlong) this);
740     env->CallVoidMethod (native.get(), AndroidFragment.setArguments, bundle.get());
741   
742     LocalRef<jobject> fm (env->CallObjectMethod (getCurrentActivity().get(), AndroidActivity.getFragmentManager));
743     env->CallVoidMethod (native.get(), AndroidDialogFragment.show, fm.get(), javaString ("FragmentOverlay").get());
744 }

Seems this is related to another issue with the current activity:
