Android P(API 28)-违反StrictMode策略“ SmartSelectionEventTracker $SelectionEvent;-> selectionAction”是

概述我正在使用StrictMode来查找非SDK用法：if(BuildConfig.DEBUG&&Build.VERSION.SDK_INT>=Build.VERSION_CODES.P){StrictMode.setVmPolicy(newStrictMode.VmPolicy.Builder().detectNonSdkApiUsage().penaltyLog().build(

我正在使用StrictMode来查找非SDK用法：

if (BuildConfig.DEBUG && Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {    StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()            .detectNonSdkAPIUsage()            .penaltyLog()            .build());}

现在,我违反了政策：

重要的一行是：

at com.mine.ui.events.EventScreen.onCreateVIEw(EventScreen.java:70)

检查上述行：

public VIEw onCreateVIEw(LayoutInflater inflater, VIEwGroup container, Bundle savedInstanceState){// This is the important line:VIEwGroup content = (VIEwGroup) inflater.inflate(R.layout.mine_event, container, false);WebVIEw webVIEw = (WebVIEw) content.findVIEwByID(R.ID.container);webVIEw.loadUrl(event.getWebVIEwUrl());webVIEw.getSettings().setJavaScriptEnabled(true);(...)

所以我在通货膨胀发生时得到了违规,我不太了解.

如您所见,在提到的那行之后不久,WebVIEw开始起作用.我看了SmartSelectionEventTracker here的源代码,它看起来像是TextVIEws,WebVIEws等控件的通用类.
WebVIEws似乎与MockVIEws有关,后者与TextVIEws有关.

但是除了这一发现之外,我还不知道违规的发生原因/原因以及我可以采取什么措施.

有人可以向我解释吗？

解决方法:

在AndroID P中,限制已添加到私有API(即,不属于公共SDK且可以通过反射访问的API).查看Restrictions on non-SDK interfaces：

AndroID 9 (API level 28) introduces new restrictions on the use of non-SDK interfaces, whether directly, via reflection, or via JNI. These restrictions are applIEd whenever an app references a non-SDK interface or attempts to obtain its handle using reflection or JNI. For more information about this decision, see Improving Stability by Reducing Usage of non-SDK Interfaces.

这就是您所看到的-这是一个警告,表明正在访问某些将来可能会删除的私有API.但是,正如您提到的,堆栈跟踪显示这是来自WebVIEw.特别是在初始化SmartSelectionClient期间.它将初始化隐式访问SmartSelectionEventTracker的本机库,该库在其Javadoc语句中用@hIDe标记,这表明它不属于公共SDK.

简而言之,对于此特定警告,您可能无能为力,所以我不必担心.它发生在设备的Chromium WebVIEw实现中,因此不在应用程序的控制范围之内.由于AndroID和Chromium都是由Google发布的,因此,如果将来的版本中存在合法问题,则将在问题发生之前将更新发布到WebVIEw实施中.
