-This directory contains a modified version of the default implementation
-provided for sensors HAL 2.0 to support multi-HAL 2.0. It should be used as a
-means to verify the multi-HAL 2.0 implementation can successfully load and
-interact with sub-HALs.
-
-This sub-HAL implementation has two macros that can be used to configure support
-for different sets of sensors. One "SUPPORT_CONTINUOUS_SENSORS", enables
-support for continuous sensors like accel, and gyro whereas the other
-"SUPPORT_ON_CHANGE_SENSORS" enables support for on change sensors like the
-light and proximity sensor. A build target is defined for each of these macros,
-but more targets could be added to support both in one sub-HAL or none at all,
-if necessary.
-
-When built, the library will be written to
-out/target/product/<device>/vendor/lib64/android.hardware.sensors@2.0-fakesubhal.so
-
-Take this .so and place it where the multi-HAL config will cause the HalProxy to
-look and then restart the system server with adb shell stop / adb shell start
-to cause the multi-HAL to restart and attempt to load in the sub-HAL.
