This CL before, this class use isAvailable() to check whether should register/unregister callback. UI will be updated when this callback called. But in one case, the isAvailable() state will not consistent on onStart() and onStop(). The isAvailable() state will not consistent when user disconnect device then forgot the device. It's will cause callback not unregister when meet this case. Then callback will duplicate call many times cause UI update not smoth. This CL use flag to confirm the callback will unreigser on onStop(). Bug: 146617530 Bug: 145647143 Test: make -j42 RunSettingsRoboTests Change-Id: I2b503ca9a7040b94ccc64ae196dad5a228fcbc6a
