我的 logcat 到底是什么意思，我该如何解决？
What exactly does my logcat mean, and how can I fix it?
出于某种原因，当 运行 在 API 23（棉花糖）或更高版本上时，我的应用程序喜欢正常工作。但是当它在 API 22 (Lollipop) 上尝试 运行 时，它立即崩溃了，我只是不明白为什么。
我试过注释除最低限度以外的任何内容，但它仍然会这样做。我发现如果不注释掉所有 webview，该应用程序甚至无法启动。
这是 logcat 我在 Android Studio 中尝试在 API 22 上模拟 Pixel 2 启动应用程序时得到的。为了进一步参考，是的，我试过了没有我的自定义 WebView class，它仍然会抛出相同的错误。

如您所见，代码没有任何问题。那有什么问题呢？ （你也可以在棒棒糖上自己测试一下）
在您的 MainActivity xml 中，您已声明 NoSuggestionsWebView class。
该错误说明您的 MainActivity xml 第 # 17 行 NoSuggestionsWebView 无法充气。
你必须检查 NoSuggestionsWebView class 并检查你是否正在做与 OS 相关的事情或类似的事情。
原来是 AVD 附带的 Android 系统 Webview 的旧版本中的一些错误，或者是因为 AppCompat 构建版本 (1.1.0) 中的错误。按照这个 所说的去做，让我的应用程序再次运行。这对我有用，因为我在 1.1.0 中并没有真正使用任何特殊的东西，所以使用 1.0.2 就可以 androidx.appcompat:appcompat:1.0.2
出于某种原因，当 运行 在 API 23（棉花糖）或更高版本上时，我的应用程序喜欢正常工作。但是当它在 API 22 (Lollipop) 上尝试 运行 时，它立即崩溃了，我只是不明白为什么。
