When Device boot and SystemUI servies starting, settings provider may callback onChange() when OneHandedController register observer. If the callback timing earlier han mEventCallback registered by WMShll#initOneHanded, then the NPE will happen. The simple fix is to add NPE check in OneHandedController#notifyExpandNotifcation() we can just ignore the callback during init time since the singal is to expand notification and come from shorcut after user enable and tap shortcut.(No need to act for the signal during boot progress.)

WM Shell Test
This contains all tests written for WM (WindowManager) Shell and it's currently divided into 3 categories
- unittest, tests against individual functions, usually @SmallTest and do not require UI automation nor real device to run
- integration, this maybe a mix of functional and integration tests. Contains tests verify the WM Shell as a whole, like talking to WM core. This usually involves mocking the window manager service or even talking to the real one. Due to this nature, test cases in this package is normally annotated as @LargeTest and runs with UI automation on real device
- flicker, similar to functional tests with its sole focus on flickerness. See WM Shell Flicker Test Package for more details
