The multihal framework is a HAL interface for the sensors framework that allows multiple vendors to package their HAL implementation into a subHAL dynamic library that will be loaded and used to pass on method calls to the appropriate subHAL. The HalProxy object, that will act as the main proxy sensors wrapper for the multiHAL handles writing sensor events to the event FMQ and wakelock acquisition and releasing via a callback object it passes to the subHALs. In order to turn your HAL 2.0 executable into a subHAL to be used by the multiHAL, implement the Return<Result> initialize(sp<HalProxyCallback>& callback) method of the ISensorsSubHal derived class. Implement the ISensorsSubHal* sensorsHalGetSubHal(uint32_t* version)method and have it return a pointer to your subHAL object. Build this into a dynamic library and list its filename under /vendor/etc/sensors/hals.conf.
