android - WebSetting allowFileAccessFromFileURLs 在 API 级别 30 中被弃用

Question

我想在 WebView 中使用 webSetting allowFileAccessFromFileURLs 但 setter 已弃用。我应该如何设置这个参数。

显然您现在应该使用 WebViewAssetLoader。引用 here .

将 implementation "androidx.webkit:webkit:x.x.x" 添加到您的 build.gradle 文件中，将 x.x.x 替换为当前版本(1.3 .0 是截至本文发布之日最新的一个)。

然后在您设置 WebView(Activity、Fragment 等)的任何地方像这样加载它:

final WebViewAssetLoader assetLoader = new WebViewAssetLoader.Builder()
           .addPathHandler("/assets/", new AssetsPathHandler(this))
           .addPathHandler("/res/", new ResourcesPathHandler(this))
           .build();
 
  webView.setWebViewClient(new WebViewClient() {
      @Override
      public WebResourceResponse shouldInterceptRequest(WebView view,
                                       WebResourceRequest request) {
          return assetLoader.shouldInterceptRequest(request.getUrl());
      }
  });
  // Assets are hosted under http(s)://appassets.androidplatform.net/assets/... .
  // If the application's assets are in the "main/assets" folder this will read the file
  // from "main/assets/www/index.html" and load it as if it were hosted on:
  // https://appassets.androidplatform.net/assets/www/index.html
  webview.loadUrl("https://appassets.androidplatform.net/assets/www/index.html");
