Set up shell to use for unit tests
Sets up a unit test file that can be used to unit test the HalProxy. The
unit tests will eventually end up containing code that injects the fake
SensorsSubHal implementation into the HalProxy and verifies various
parts of the implementation. This will likely require some modifications
to the SensorsSubHal class to modify it during test execution, but it's
better that the same implementation is shared between unit / manual
integration testing.
Test: Run atest android.hardware.sensors@2.0-halproxy-unit-tests

+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.
