- * From the Chromium architecture point of view, ViewAndroid and its native counterpart

- * handle to the system view type. As Views are Java object on Android, this ViewAndroid
- * and its native counterpart provide the expected abstractions on the C++ side and allow
- * it to be flexibly glued to an actual Android Java View at runtime.
- *
- * It should only be used where access to Android Views is needed from the C++ code.
