The new HAL will be responsible for processing touch video frames that are received from InputClassifier stage. After processing, the HAL will generate a classification of the current gesture. This classification will later be provided to the app via the MotionEvent.getClassification() public API. The eventual goal is to classify each event stream as a force touch or not a force touch. An example implementation of the HAL is presented here. This code was used for local testing on blueline, and should not be actually installed or used in any way other than for reference. Bug: 62940136 Test: observed "detected deep press" logs when pressing with large finger area on the touchscreen Change-Id: Id6ac4337435e4ac07877da11ca184b6dd4d64780
