在Android中使用辅助功能获取大量ANR
[英]Getting lot of ANR using Accessibility service in android
问题描述
i am getting ANR from reports 
我从报告中获取ANR
Broadcast of Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.google.android.apps.maps flg=0x4000010 cmp=xx.xx.xx/com.microsoft.aad.adal.ApplicationReceiver (has extras) }
Broadcast of Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.google.android.apps.translate flg=0x4000010 cmp=xx.xx.xx/com.microsoft.aad.adal.ApplicationReceiver (has extras) }
"main" prio=5 tid=1 TimedWaiting |

My code is 我的代码是
ArrayList<AccessibilityNodeInfo> collectNodes(AccessibilityNodeInfo node) {
ArrayList<AccessibilityNodeInfo> nodeInfoArrayList = new ArrayList<>();
try {
int childCount = node.getChildCount();
for (int index = 0; index < childCount; index++) {
AccessibilityNodeInfo childNode = node.getChild(index);
traverseNode(childNode);
if (childNodes != null && childNodes.size() > 0) {
nodeInfoArrayList.addAll(childNodes);
childNodes.clear();
}
}
}
catch (Exception e){
e.printStackTrace();
}
return nodeInfoArrayList;
}
private void traverseNode(AccessibilityNodeInfo node) {
try {
AccessibilityNodeInfo edittextNode = null;
if (null == node)
return;
final int count = node.getChildCount();
if (count > 0) {
for (int i = 0; i < count; i++) {
AccessibilityNodeInfo childNode = node.getChild(i);
if (childNode == null) {
node.recycle();
return;
}
else {
traverseNode(childNode);
}
}
} else {
}
}
catch (Exception error){
error.printStackTrace();
}
}
Any idea how to resolve this issue 任何想法如何解决这个问题

If an app doesn't respond to the request for the AccessibilityNodeInfo, the request for it from the AccessibilityService will time out and return null. 如果应用程序不响应对AccessibilityNodeInfo的请求，则AccessibilityService对它的请求将超时并返回null。 That timeout is set to 5s. 该超时设置为5s。
If you make repeated requests from the unresponsive app, you can end up with very long waits. 如果您从无响应的应用程序中重复发出请求，则可能会导致很长的等待时间。
In the first part of the code shown, the loop will continue trying to traverse nodes even if that fails. 在所示代码的第一部分中，即使失败，循环也将继续尝试遍历节点。 That can lead to very long delays. 这会导致很长的延迟。

This error is reported on Android 6, and 7.1, but mostly on android 7.0 此错误是在Android 6和7.1上报告的，但大多数是在android 7.0上报告的
UPDATE: 更新：
- we don't have a lot of user on android 8 yet, but I also see the problem on android 8. 我们在android 8上没有很多用户，但是我也在android 8上看到了问题。
- I still got no clue about how to fix that. 我仍然不知道如何解决该问题。

I found issue, actually this is issue due to onedrive-sdk-android 我发现了问题，实际上这是由于onedrive-sdk-android而引起的问题
As per onedrive i use below code 根据一个驱动器，我使用以下代码
repository {
jcenter()
}
dependency {
// Include the sdk as a dependency
compile ('com.onedrive.sdk:onedrive-sdk-android:1.3+') {
transitive = false
}
// Include the gson dependency
compile ('com.google.code.gson:gson:2.3.1')
// Include supported authentication methods for your application
compile ('com.microsoft.services.msa:msa-auth:0.8.+')
compile ('com.microsoft.aad:adal:1.1.+')
}
and below line 和下面的线
compile ('com.microsoft.aad:adal:1.1.+')
create error which i found here , after change compile ('com.microsoft.aad:adal:1.1.+') to compile ('com.microsoft.aad:adal:1.13.1') resolved issue. 创建我在这里发现的错误，将更改compile ('com.microsoft.aad:adal:1.1.+')更改为compile ('com.microsoft.aad:adal:1.13.1')解决的问题。
