Can this in any way return NULL? Or is this always successfully created?

Looks like it can only be NULL if your platform doesn't support invalidations
(which is just Chrome OS).

+  InvalidationServiceAndroid* service_android =
+      static_cast<InvalidationServiceAndroid*>(
+          provider->GetInvalidationService());
+  return service_android->java_ref_.obj();
+}
+
+jobject InvalidationServiceFactoryAndroid::GetForTest(JNIEnv* env,
+                                                      jclass clazz,
+                                                      jobject j_context) {
+  InvalidationServiceAndroid* service_android =
+      new InvalidationServiceAndroid(j_context);
+  return service_android->java_ref_.obj();

If you want to do community work, feel free to add support for calling static
class-methods in our JNI generator! It would basically just do something similar
to what you are doing here, but automatically.

Acknowledged.
