我们在 :

安卓版本：5、6、7

设备制造商：联想、oneplus、三星、摩托罗拉

而且，这些设备没有植根。

搜索了一段时间后，我找不到任何合适的原因（和处理）。也经历了 这个 问题，但没有任何解决方案。

请帮忙。

编辑：我们的很多用户都会遇到这种情况，所以我不能告诉大家从 Play 商店检查/安装 webiew。有更好的解决方案吗？

我在这里发现了一个可能的问题。正如我们所知，webview 已经作为一个独立的应用程序从 android 5.0 中发布，可能是 在我的视图被膨胀时，操作系统正在更新 webview 包，因此它找不到 webview pacakge对于那些片刻。我知道这是一个非常边缘的案例，但是

  • 如我所见，崩溃仅发生在 >= 5.0 支持此假设的设备上
  • 很难相信所有这些设备都没有安装 webview。事实上，我尝试从我的设备上卸载系统和 chrome 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，但可以防止崩溃）：

 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
        }
    }

基本上只是处理那个异常。那里没有火箭科学。

我在 Android 12 中遇到了同样的问题。我在我的 Play 商店应用程序中打开了 Android System Webiew 并将其卸载。卸载后，我通过单击“启用”按钮启用了它。那对我有用。
