最近,我们开始在我们的crashlytics中看到这个新条目,该条目表示

我们看到这个：
Android版本：5,6,7
设备制造商：联想,oneplus,三星,摩托罗拉
并且,设备没有根植.
搜索一段时间后,我无法找到任何适当的原因(和处理).经过this问题,但它没有任何解决方案.
请帮忙.
解决方法
我在这里想出了一个可能的问题.我们知道webview已经作为一个单独的应用程序从android 5.0发布,可能是因为当我的视图被夸大时,webview包正在由os更新,因此无法找到webview pacakge那几分钟.我知道这是一个非常边缘的案例但是
>正如我所看到的,崩溃只发生在支持这一假设的> = 5.0设备上
>很难相信所有这些设备都没有安装webview.事实上,我尝试从我的设备卸载系统和chrome软件包,但应用程序仍然没有崩溃.
所以这就是我所做的(hacky解决方案,但防止崩溃)：
try {
// the inflating code that's causing the crash
} catch (Exception e) {
if (e.getMessage() != null && e.getMessage().contains("webview")) {
// If the system Failed to inflate this view because of the WebView (which Could
// be one of several types of exceptions),it likely means that the system WebView
// is either not present (unlikely) OR in the process of being updated (also unlikely).
// It's unlikely but we have been receiving a lot of crashes.
// In this case,show the user a message and finish the activity
}
}
基本上只是处理该异常.那里没有火箭科学.
