Chromium webview 似乎不适用于 Android applyOverrideConfiguration

在我的更改描述之后使用 resConfig 强制 Android 风格的区域设置 https://stackoverflow.com/questions/31566270/force-locale-for-android-flavor-with-resconfig/31787201#31787201我遇到了包含视频的网络视图的问题。该问题仅存在于 API21+ 上，并且在删除对 applyOverrideConfiguration 的调用后真正消失。不太确定如何解决这个问题。

从我在 grepcode 上找到的内容来看，这将是在获取 ic_media_video_poster 图像时。我验证了该图像确实在 sdk 中。http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.0.1_r1/com/android/webview/chromium/WebViewContentsClientAdapter.java#WebViewContentsClientAdapter.getDefaultVideoPoster%28% 29 http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.0.1_r1/com/android/webview/chromium/WebViewContentsClientAdapter.java#WebViewContentsClientAdapter.getDefaultVideoPoster%28%29

public Bitmap More ...getDefaultVideoPoster() {
     TraceEvent.begin();
     Bitmap result = null;
     if (mWebChromeClient != null) {
         if (TRACE) Log.d(TAG, "getDefaultVideoPoster");
         result = mWebChromeClient.getDefaultVideoPoster();
     }
     if (result == null) {
         // The ic_media_video_poster icon is transparent so we need to draw it on a gray
         // background.
         Bitmap poster = BitmapFactory.decodeResource(
                 mWebView.getContext().getResources(),
                 R.drawable.ic_media_video_poster);
         result = Bitmap.createBitmap(poster.getWidth(), poster.getHeight(), poster.getConfig());
         result.eraseColor(Color.GRAY);
         Canvas canvas = new Canvas(result);
         canvas.drawBitmap(poster, 0f, 0f, null);
     }
     TraceEvent.end();
     return result;
 }

EDIT：经过几次测试，我能够在 testApp 中隔离崩溃。它可以在我在 Chromium 上创建的错误报告中找到https://code.google.com/p/chromium/issues/detail?id=521753 https://code.google.com/p/chromium/issues/detail?id=521753

有任何想法吗？有人已经遇到过这个问题了吗？

正如@Martin Edelman评论了 https://stackoverflow.com/questions/32050784/chromium-webview-does-not-seems-to-work-with-android-applyoverrideconfiguration#comment57279676_32050784，它应该适用于此解决方法：

在科特林中：

override fun getAssets(): AssetManager {
    return resources.assets
}

In Java:

@Override
public AssetManager getAssets() {
    return getResources().getAssets();
}
