Android 12 下兼容性出现问题，运行一段时间后会无法连接

[icegourd]

之前测试代码运行都很正常，手机升级为Android12后，运行测试代码刚开始还正常，但是很短时间内就会出现异常，无法重新连接上。 出现错误代码如下：

[E 211013 13:13:24 web:2250] 500 GET /api/v2/devices/android%AAAAAAAA/hierarchy (::1) 425.75ms [I 211013 13:17:07 page:297] Serial: AAAAAAAA [I 211013 13:17:13 web:2250] 200 GET /api/v1/devices/android%AAAAAAAA/screenshot (::1) 5580.32ms [W 211013 13:17:13 init:471] [pid:3964] jsonrpc call got: -32001 Jsonrpc error: <java.lang.NullPointerException> data: java.lang.NullPointerException: Attempt to read from field 'int android.accessibilityservice.AccessibilityServiceInfo.flags' on a null object reference at androidx.test.uiautomator.UiDevice.setCompressedLayoutHeirarchy(UiDevice.java:234) at com.github.uiautomator.stub.AutomatorServiceImpl.dumpWindowHierarchy(AutomatorServiceImpl.java:295) at com.github.uiautomator.stub.AutomatorServiceImpl.dumpWindowHierarchy(AutomatorServiceImpl.java:284) at java.lang.reflect.Method.invoke(Native Method) at com.googlecode.jsonrpc4j.JsonRpcBasicServer.invoke(JsonRpcBasicServer.java:467) at com.googlecode.jsonrpc4j.JsonRpcBasicServer.handleObject(JsonRpcBasicServer.java:352) at com.googlecode.jsonrpc4j.JsonRpcBasicServer.handleJsonNodeRequest(JsonRpcBasicServer.java:283) at com.googlecode.jsonrpc4j.JsonRpcBasicServer.handleRequest(JsonRpcBasicServer.java:251) at com.github.uiautomator.stub.AutomatorHttpServer.serve(AutomatorHttpServer.java:100) at fi.iki.elonen.NanoHTTPD.serve(NanoHTTPD.java:2244) at fi.iki.elonen.NanoHTTPD$HTTPSession.execute(NanoHTTPD.java:945) at fi.iki.elonen.NanoHTTPD$ClientHandler.run(NanoHTTPD.java:192) at java.lang.Thread.run(Thread.java:920) , method: dumpWindowHierarchy

我怀疑是uiautomater服务出了问题，因为如果手动在 ATX APP中点击“停止UIAUTOMATOR”按钮后，这时候运行测试代码，获得的错误信息是一样的。

进一步确定uiautomater服务停止了： 出现问题后

1. 在weditor中执行 d.uiautomator.running() 返回false
2. 执行 atx-agent 的curl命令，同样返回false adb shell /data/local/tmp/atx-agent curl http://127.0.0.1:7912/services/uiautomator 2021/10/13 14:45:46 goreq.go:390: GET /services/uiautomator HTTP/1.1 Host: 127.0.0.1:7912 2021/10/13 14:45:46 curl.go:116: {"running":false,"success":true}

• 手机型号 Nokia X10（Android 12）

• uiautomator2的版本号(pip show uiautomator2) Version: 2.16.7

• 手机截图

• 相关日志(Python控制台错误信息, adb logcat完整信息, atxagent.log日志)

atx-agent.daemon.log atx-agent.log

Python 出现3次下列错误消息后问题出现：
