| The Rule API is a library intended for view authors to add designtime | |
| support for their custom views in Android layout editors. | |
| NOTE: The API is *not* final and will very likely continue to change | |
| incompatibly until we finish it and incorporate feedback. | |
| The rule API attempts to be IDE agnostic, so it should not have | |
| specific dependencies on any tools. IDE vendors building layout | |
| editors should provide IDE-side implementations of the rule interfaces | |
| such that they can interact with view rules. |
