| 20 | * Adapts and plumbs android IME service onto the chrome text input API. |
| 21 | * ImeAdapter provides an interface in both ways native <-> java: |
| 22 | * 1. InputConnectionAdapter notifies native code of text composition state and |
| 23 | * dispatch key events from java -> WebKit. |
| 24 | * 2. Native ImeAdapter notifies java side to clear composition text. |
| 25 | * |
| 26 | * The basic flow is: |
| 27 | * 1. When InputConnectionAdapter gets called with composition or result text: |
| 28 | * If we receive a composition text or a result text, then we just need to |
| 29 | * dispatch a synthetic key event with special keycode 229, and then dispatch |
| 30 | * the composition or result text. |
| 31 | * 2. Intercept dispatchKeyEvent() method for key events not handled by IME, we |
| 32 | * need to dispatch them to webkit and check webkit's reply. Then inject a |
| 33 | * new key event for further processing if webkit didn't handle it. |
| 34 | * |
| 35 | * Note that the native peer object does not take any strong reference onto the |
| 36 | * instance of this java object, hence it is up to the client of this class (e.g. |
| 37 | * the ViewEmbedder implementor) to hold a strong reference to it for the required |
| 38 | * lifetime of the object. |
