Subject: Add isAvailable check to devOptionsController
X-Git-Tag: android-x86-9.0-r1~194^2~11^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=f5539a196995bcee365b9b7786c98b3e4c9feaf6;p=android-x86%2Fpackages-apps-Settings.git

Add isAvailable check to devOptionsController

Test: make RunSettingsRoboTests -j40
