我们在上看到了这一点:
We are seeing this on :
Android版本:5、6、7
Android versions : 5,6,7
设备制造商:联想，oneplus，三星，摩托罗拉
Devices Manufacturers: Lenovo, oneplus, samsung, motorola
而且，设备没有植根.
搜索了一会儿之后，我无法找到任何合适的原因(和处理方法).还通过了此问题，但没有任何问题解决方案.
After searching for a while, I am not able to find any appropriate cause (and handling) for this. Went through this question also but it doesn't have any solution.
请帮助.
我们许多用户都在发生这种情况，因此我无法告诉所有人从Play商店检查/安装webiew. 有更好的解决方案吗?
Edit : This is happening for a lot of our users, so I can't go and tell everyone to check/install webiew from the play store. Is there a better solution for this?
推荐答案
我在这里发现了一个可能的问题.我们知道webview已作为与Android 5.0分离的应用程序发布，可能是在我的视图膨胀时，操作系统正在更新webview包，因此找不到这段时间里，webview会运行.我知道这是一个非常临界的情况，但
I figured out a probable problem here. As we know that webview has been shipping as a separate app from android 5.0, it may be the case that at the time my view is being inflated, the webview package is being updated by the os and therefore it can't find the webview pacakge for those few moments. I know it's a very borderline case but
- 如我所见，崩溃仅在支持此假设的> = 5.0设备上发生
- 很难相信所有此类设备都未安装webview.实际上，我尝试从设备上卸载系统和Chrome程序包，但该应用程序仍然不会崩溃.
这就是我的工作(可靠的解决方案，但可以防止崩溃):
So here's what I did (hacky solution but prevents crashes):
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
}
}
除了处理该异常外，基本上什么也没有.那里没有火箭科学.
Basically nothing but handling that exception. No rocket science there.
这篇关于android无法加载WebView提供程序:未安装WebView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！
