This CL shows an example of how to use and retrieve a HAL extension. Bug: 136027762 Test: run HAL and: - use "dumpsys --pid android.hardware.vibrator.IVibrator/default" to make sure that the HAL I'm running is the binary being added. - VtsHalVibratorTargetTest - test-vintf-vibrator-ext-client Change-Id: I8614007a727e8e05ba4667c2cd1623ce936a1609
