c++ style should be SetWindowAndroid (capitalizing the first letter)...same for
GetWindowAndroid

that is unless you want to inline these and then it should be the hacker naming
scheme of:

set_window_android(ui::WindowAndroid* window_android) {
  window_android_ = window_android;
}

Also, just saw and it should be window_android for the variable name.

Done.
