我开发了一款移动 HTML5 游戏，当我从网络加载 URL 时它运行良好。但是当我显示从 Android 4.0 上的 Assets 文件夹调用 JavaScript 的 index.html 时，它不起作用。我在下面包含了 logcat 和代码。
public class BlockyBlaine extends Activity {
WebView webview;
AdView adView;
private class BlaineViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
adView = (AdView) findViewById(R.id.adView);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setPluginsEnabled(true);
webview.getSettings().setSupportZoom(false);
webview.setVerticalScrollBarEnabled(false);
webview.setHorizontalScrollBarEnabled(false);
webview.getSettings().setUseWideViewPort(false);
webview.getSettings().setDomStorageEnabled(true);
webview.loadUrl("file:///android_asset/www/index.html");
webview.setWebViewClient(new BlaineViewClient());
webview.setFocusableInTouchMode(false);
adView.loadAd(new AdRequest());
}
}

最佳答案
这只是瞎猜，但看起来您的模拟器需要您调用，
AdRequest adRequest = new AdRequest();
adRequest.addTestDevice(AdRequest.TEST_EMULATOR);
在打电话之前，
adView.loadAd(adRequest);
编辑:
阅读this和 this .看起来 Android 团队决定“file:///scheme”是不安全的(从 4.0 开始)。
也许您可以将 Assets 上传到保管箱(或在线某个地方)，然后在运行时下载文件。
