Subject: Hearing Aid: change get/set active device (1/3)
X-Git-Tag: android-x86-9.0-r1~98^2~6^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=8d5f67935053e76958ff6ddd773b5e8484ea802f;p=android-x86%2Fsystem-bt.git

Hearing Aid: change get/set active device (1/3)

* setActiveDevice() returns false in error case, e.g. when the device is
not connected
* add getActiveDevices() instead of isActiveDevice(), which returns a list
that must have two elements: left and right, or empty list on error

Test: manual
