-/**
- * Adapts and plumbs android IME service onto the chrome text input API.
- * ImeAdapter provides an interface in both ways native <-> java:
- * 1. InputConnectionAdapter notifies native code of text composition state and
- * dispatch key events from java -> WebKit.
- * 2. Native ImeAdapter notifies java side to clear composition text.
- *
- * The basic flow is:
- * 1. When InputConnectionAdapter gets called with composition or result text:
- * If we receive a composition text or a result text, then we just need to
- * dispatch a synthetic key event with special keycode 229, and then dispatch
- * the composition or result text.
- * 2. Intercept dispatchKeyEvent() method for key events not handled by IME, we
- * need to dispatch them to webkit and check webkit's reply. Then inject a
- * new key event for further processing if webkit didn't handle it.
- *
- * Note that the native peer object does not take any strong reference onto the
- * instance of this java object, hence it is up to the client of this class (e.g.
- * the ViewEmbedder implementor) to hold a strong reference to it for the required
- * lifetime of the object.
