java - 我的 logcat 到底是什么意思，我该如何解决它？

标签 java android webview mobile-application

出于某种原因，我的应用程序在 API 23 (Marshmallow) 或更高版本上运行时工作得很好。但是当它尝试在 API 22(Lollipop)上运行时，它立即崩溃，我只是不明白为什么。

我已经尝试注释掉除最低限度之外的任何内容，但它仍然会这样做。我发现如果不注释掉所有 WebView ，应用程序甚至无法启动。

这是我尝试在 Android Studio 中启动应用程序并在 API 22 上模拟 Pixel 2 时得到的 logcat。为了进一步引用，是的，我在没有自定义 WebView 类的情况下尝试了它，但它仍然抛出相同的错误。

我原以为它会启动(也许看起来不是最好的，因为使用较旧的 API 时 webview 支持是不同的)，但它似乎因为通货膨胀异常而崩溃？ (除非我读错了)

编辑:我刚刚尝试仅使用 1 个 WebView 创建一个全新的应用程序，也很简单，而且它也会崩溃。这是activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

这是 MainActivity.java

package test.webview;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    private WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webView = (WebView) findViewById(R.id.webView);

        webView.loadUrl("https://google.com");
    }
}

如您所见，代码没有任何问题。那么可能出了什么问题呢？ (您也可以在 Lollipop 上亲自测试一下)

最佳答案

在您的 MainActivity xml 中，您已声明 NoSuggestionsWebView 类。

该错误解释说，在 MainActivity xml 的第 17 行 NoSuggestionsWebView 无法膨胀。

您必须检查 NoSuggestionsWebView 类并检查您是否正在执行与操作系统相关的操作或类似操作。
