| 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. |
