Chromium Webview似乎不适用于Android applyOverrideConfiguration [英] Chromium webview does not seems to work with Android applyOverrideConfiguration

问题描述

按照我的更改，在为Android风格强制设置区域设置resConfig 我遇到了包含视频的网络视图的问题。该问题仅在API21 +上存在，并且在删除对applyOverrideConfiguration的调用时实际上消失了。不确定如何解决。

Following my change describe in Force locale for Android flavor with resConfig I am facing a problem with webviews containing video. The issue is only on API21+ and really disappear when removing the call to applyOverrideConfiguration. Not so sure how to get around that.

F rom我可以在grepcode上找到ic_media_video_poster图像。.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

From what I could find on grepcode it would be while getting the ic_media_video_poster image.. I validated that this image is really in the sdk. 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;
 }

编辑：经过几次测试，我能够在testApp中隔离崩溃。我在Chromium上创建的错误报告中提供了该报告， https://code.google .com / p / chromium / issues / detail？id = 521753

EDIT: After a few more test, I was able to isolate the crash in a testApp. It is available in the bugreport I created on Chromium https://code.google.com/p/chromium/issues/detail?id=521753

有什么想法吗？有人遇到了这个问题吗？

Any ideas? As anyone faced this problem already?

推荐答案

就像@Martin Edlman 已评论，它应可通过以下解决方法工作：

As @Martin Edlman commented, it should work with this workaround:

在科特林：

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

在Java中：

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