请注意几乎所有来自Android 8.0设备的ANR报告。
<第一个重要的事情是回收所有由getChild分配的节点，findAccessibilityNodeInfoByAccessibilityId或其他任何函数。所以你应该有这样的东西：
lockquote

if（rootNode == null）return null;
if（rootNode.getText（）！= null&& rootNode.getText（）。toString（）。equals（text））

int childCount = rootNode.getChildCount（）;
for（int i = 0; i< childCount; i ++）{
AccessibilityNodeInfo tmpNode = rootNode.getChild（i）;
if（tmpNode！= null）{
AccessibilityNodeInfo res = findFirstViewByText（tmpNode，text）;
if（res！= null）{
return res;
} else {
tmpNode.recycle（）;
}
}
}
返回null;
}
}
node = findFirstViewByText（rootNode，something）;

even more issues in Android 8.0. Any idea how to deal with these ANR's.
config.xml file

android:notificationTimeout="100"
android:canRetrieveWindowContent="true"
android:accessibilityFeedbackType="feedbackGeneric"
android:accessibilityFlags="flagReportViewIds|flagRequestEnhancedWebAccessibility"
android:description="Test"/>
please note almost all the ANR report from Android 8.0 devices.
- The first important thing is to recycle all the nodes allocated by
getChild,findAccessibilityNodeInfoByAccessibilityIdor any other function. So you should have something like this:
AccessibilityNodeInfo findFirstViewByText(AccessibilityNodeInfo rootNode, String text) { if (rootNode == null) return null; if (rootNode.getText() != null && rootNode.getText().toString().equals(text)) return rootNode; int childCount = rootNode.getChildCount(); for (int i = 0; i < childCount; i++) { AccessibilityNodeInfo tmpNode = rootNode.getChild(i); if (tmpNode != null) { AccessibilityNodeInfo res = findFirstViewByText(tmpNode, text); if (res != null) { return res; } else { tmpNode.recycle(); } } } return null; } } node = findFirstViewByText(rootNode, "something"); if(node != null) { node.performAction(AccessibilityNodeInfo.ACTION_CLICK); node.recycle(); }
Keep in mind that
onAccessibilityEventmay be called too often while you interact with the target application and also your processing in this function is blocking UI Thread on the target application. You can overcome this by:- Throttling the calls to
onAccessibilityEventi.e. don't execute your code if the last execution happened less than x milliseconds ago, but make sure that last call will trigger execution of your code. - Improve the performance of your code by avoiding unnecessary traversing. Define states so the app will look only for the nodes relevant for the current state.
- Throttling the calls to
Feel free to share more of your code so i/we can understand what exactly is your goal, that way we can be more helpful. As i can see from your log, there are several threads traversing the virtual dom of accessibility service and they are causing deadlock.
这篇关于由于AccessibilityNodeInfo getChild获取大量的ANR的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
