显示youtube视频时Webview崩溃 [英] Webview crashes when displaying a youtube video

问题描述

更新到8.0后，我们到目前为止还没有发生过崩溃:

After updating to 8.0 we get a crash so far we haven't seen before:

java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference
                                                                 at com.android.webview.chromium.WebViewContentsClientAdapter.getDefaultVideoPoster(WebViewContentsClientAdapter.java:536)
                                                                 at org.chromium.android_webview.DefaultVideoPosterRequestHandler$1.run(DefaultVideoPosterRequestHandler.java:2)
                                                                 at android.os.Handler.handleCallback(Handler.java:789)
                                                                 at android.os.Handler.dispatchMessage(Handler.java:98)
                                                                 at android.os.Looper.loop(Looper.java:164)
                                                                 at android.app.ActivityThread.main(ActivityThread.java:6541)
                                                                 at java.lang.reflect.Method.invoke(Native Method)
                                                                 at com.android.internal.os.Zygote$MethodAndArgsCaller.run(Zygote.java:240)
                                                                 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:767)

这是Chrome中的错误吗?

Is this a bug in Chrome?

推荐答案

由于@breakline的回答，我解决了这个问题！谢谢！ 但是，我没有使用解码位图，而是创建了一个空的位图并返回:

Thanks to @breakline's answer, I got this issue worked around! Thanks! But instead of using decoding a bitmap, I just create an empty one and return that:

    setWebChromeClient(new WebChromeClient() {
        @Override
        public Bitmap getDefaultVideoPoster() {
            return Bitmap.createBitmap(50, 50, Bitmap.Config.ARGB_8888);
        }
    });
