ROM and version(manager): （你的 ROM 和 manager 的版本）

• Name: [e.g. Lineage OS]
• Android Version: [e.g. 8.1]
• Version [e.g. 0.3.4 stable]
  魔趣每夜版，安卓9，MiPush最新pre release 版

Additional context

Start in MainFragment.refreshStatus at line 198, where the log reports a null SwitchCompat, and trace the call from MainFragment.onChange and MainActivity.ConnectTask.onReady. Reproduce by opening the manager and inspect the relevant view setup. Done means the manager opens without the reported NullPointerException.
