老师,当启动图结束后用户登录了,需要启动EcBottomDelegate时,发现
getSupportDelegate().startWithPop(new EcBottomDelegate());
无法启动EcBottomDelegate(),模拟器上显示空白,AS提示信息:
LauncherDelegate's FragmentManager is null, Please check if LauncherDelegate is destroyed!
不知道为什么LauncherDelegate's FragmentManager会变null。但是用start方法可以启动:
getSupportDelegate().start(new EcBottomDelegate());
为什么?startWithPop和start有啥不同的么?
