  • Status changed from ASSIGNED to RESOLVED
  • Assignee changed from CD FW-廖涛 to CD TEST-方永红
  • % Done changed from 0 to 100
  • Resolution changed from -- to FIXED
  • Degrated changed from -- to No
  • Fixed Version set to 2023-04-12
  • Root cause set to WebView Navite 问题

■ Current conclusion
已处理，代码已入库。

■ My analysis
通过崩溃日志可知，错误发生在 WebView Navite 代码逻辑中，由于 WebView 是以 apk 的形式集成到系统，所以将 WebView 版本从 95.0.4638.74 更新到 101.0.4951.61 。

备注：WebView 在设备使用过程中是可以根据商店或 Google Play 发布的新版进行更新的。

■ Next action
测试验证。

■ My analysis
该 CRASH 是由 libwebviewchromium.so 报出的 native 崩溃，通过查询 stackoverflow 和 google 官方论坛，可以看出，该问题在 Android 7.0+ 以上一直存在，并且官方认为不需要修复。该问题可以从第三方应用在使用 WebView 的方式上进行规避。并且为小概率问题，无需修复。

Hi 永红
当前问题说明
谷歌原生webview应用在monkey测试中偶现crash

研发对于这个问题的修复方式, 因为该apk应用是谷歌原生的，我们无法修改起源代码，只能通过尝试更新谷歌官方分支的apk文件来改善
但是目前更新版本后仍然存在问题

因此基于下列理由，此问题我们申请不解
1.该apk应用是谷歌原生的，我们无法修改其源代码，只能通过尝试更新谷歌官方分支的apk文件来改善，研发无法做更多处理
2.通过调查，该问题在 Android 7.0+ 以上一直存在，并且官方认为不需要修复。建议在从第三方应用使用 WebView 的方式上进行规避，这个需要看三方应用内部实现
3.该问题复现场景比较罕见，遇见的概率极低
4.复现后除了wedview在该特种情况下，无法使用，并无其他影响，不会影响系统的正常运行

综上，请考虑此问题不解

麻烦做一下技术评估，看是否需求修改

可以暂时不用修改，但monkey跑出来仍然需要记录，等其他monkey问题都解决完毕，并且时间也能满足要求后，如果还有这个apk的crash最后再来评估。目前这个票可以关闭。
