Summary: For iOS, event category deduction is done from the C++ code, but the touch events are handled on Java layer in Android. This change exposes the category parameter through the `EventEmitterWrapper` called from Java, allowing to define category for events in the future. Changelog: [Internal] - Expose event category through JNI Reviewed By: mdvacca Differential Revision: D31205587 fbshipit-source-id: f2373ce18464b01ac08eb87df8f421b33d100be2
