I’m on a Mac (Ventura 13.1)
Unreal Engine 4.27 (Version: 4.27.2-18319896+++UE4+Release-4.27)
Android Studio 4.0
Android SDK Build Tools 30.0.3 and 29.0.2
Android NDK 21.4.7075529
Android Command Line Tools 9.0, 8.0, and 7.0

Maybe someone can help…

Here is the error I am getting when I’m trying to package things for Android:

不要使用安卓 33的sdk,可以使用安卓32,在安卓33 中setAppCacheMaxSize这个函数已经被删除了.如果需要使用安卓33的sdk需要修改java文件.
修改如下 打开这个路径UE_4.27\Engine\Build\Android\Java\src\com\epicgames\ue4
打开WebViewControl.java这个文件将
webView.getSettings().setAppCacheMaxSize( 10 * 1024 * 1024 );
webView.getSettings().setAppCachePath(GameActivity._activity.getApplicationContext().getCacheDir().getAbsolutePath() );
webView.getSettings().setAppCacheEnabled( true );
删除或者注释掉添加这行代码
webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
完整代码如下:
// create the WebView
webView = new GLWebView(GameActivity._activity);
webView.setWebViewClient(new ViewClient());
webView.setWebChromeClient(new ChromeClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
//webView.getSettings().setAppCacheMaxSize( 10 * 1024 * 1024 );
//webView.getSettings().setAppCachePath(GameActivity._activity.getApplicationContext().getCacheDir().getAbsolutePath() );
webView.getSettings().setAllowFileAccess( true );
//webView.getSettings().setAppCacheEnabled( true );
webView.getSettings().setAllowContentAccess( true );
webView.getSettings().setAllowFileAccessFromFileURLs(true);
webView.getSettings().setAllowUniversalAccessFromFileURLs(true);
webView.getSettings().setSupportMultipleWindows(true);
webView.getSettings().setDomStorageEnabled(bEnableDomStorage);
webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
