"""重建被误删的 onCreate —— 这就是白屏的原因。

事故经过：
    我的 purge_diagnostics.py 用"方法体里出现标记就删掉整个方法"的策略，
    而 onCreate 里调了 buildDiagPanel()，于是**整个 onCreate 被删了**。

    它照样能编译（Activity.onCreate 不是抽象方法），
    但 setContentView 永远不执行 -> 白屏、点了没反应。

从现存代码反推出的 onCreate 该做什么：
    store / ui / client 初始化   （这三个字段现在没人赋值）
    root = FrameLayout
    buildConnectPanel() / buildControlPanel() / buildMirrorPanel()
    三块面板都挂到 root 上，默认只显示 connectPanel
    setContentView(root)
    installCrashGuard()          （内部用 ui，必须在 ui 之后）
    requestStartupPermissions()
    refreshDeviceList()
