请帮忙分析下这个问题

■ Current conclusion
在最新的monkey测试中,没有出现该anr了

■ My analysis
从日志看, system_server的anr发生在21:23:11,原因是Input事件没有在5s内响应.

----- pid 1136 at 2022-11-04 21:23:11.587288660+0800 -----
Cmd line: system_server

结合前后21:23:11的前后日志分析

在发生ANR之前是要启动QuickstepLauncher
11-04 21:23:02.755 7497 7497 I wm_on_restart_called: [211429863,com.android.launcher3.uioverrides.QuickstepLauncher,performRestartActivity]
11-04 21:23:02.755 7497 7497 I wm_on_start_called: [211429863,com.android.launcher3.uioverrides.QuickstepLauncher,handleStartActivity]
11-04 21:23:02.757 7497 7497 I wm_on_resume_called: [211429863,com.android.launcher3.uioverrides.QuickstepLauncher,RESUME_ACTIVITY]

QuickstepLauncher开始请求焦点
11-04 21:23:02.787 1136 1213 I input_focus: [Focus request 8795ff6 com.android.launcher3/com.android.launcher3.uioverrides.QuickstepLauncher,reason=UpdateInputWindows]

Monkey发生Touch事件
11-04 21:23:02.883 7301 7301 I Monkey : :Sending Touch (ACTION_UP): 0:(2137.013,523.9981)
11-04 21:23:02.881 7301 7301 I Monkey : :Sending Touch (ACTION_DOWN): 0:(2135.0,538.0)

但是这个时候QuickstepLauncher还没有获取到焦点
11-04 21:23:03.088 1136 1706 W InputDispatcher: Waiting because no window has focus but ActivityRecord{c9a29e7 u0 com.android.launcher3/.uioverrides.QuickstepLauncher t8} may eventually add a window when it finishes starting up. Will wait for 5000ms

QuickstepLauncher启动5s后还是没有获取焦点,所以Input event被废弃了
11-04 21:23:07.887 1136 1706 I InputDispatcher: Dropped event because of pending overdue app switch.
11-04 21:23:07.889 1136 1706 W InputDispatcher: Monitor PointerEventDispatcher0 (server) is unresponsive: PointerEventDispatcher0 (server) is not responding.

11-04 21:23:07.889 1136 1706 W InputDispatcher: Canceling events for PointerEventDispatcher0 (server) because it is unresponsive
11-04 21:23:07.891 1136 1164 W InputManager: Input event injection from pid 7301 failed.

目前看起来有点像是QuickstepLauncher启动超时导致的,但是在最新的版本上跑monkey时,没有发生该anr了,所以建议先观察几个版本在看看
