我有带有 XWalkView 的 Android 原生应用程序。一切正常，直到进入 html5 视频全屏模式（youtube 或简单的 html 视频标签）。

在 logcat 和应用程序崩溃中出现错误：

03-01 23:23:27.759 7879-7879/? E/chromium：[ERROR:xwalk_autofill_client.cc(116)] 未在虚拟 void xwalk::XWalkAutofillClient::OnFirstUserGestureObserved() 中实现

03-01 23:23:27.909 7879-7879/? A /铬：[致命：jni_android.cc（249）]检查失败：假。请在崩溃报告中包含 Java 异常堆栈

03-01 23:23:27.909 7879-7879/? A/libc: 致命信号 11 (SIGSEGV) at 0xdeadbaad (code=1), thread 7879 (eu.my.app.MyApp)

应用程序代码只是来自人行横道网站的示例：

public class MyActivity extends XWalkActivity {
XWalkView mXwalkView;

class MyResourceClient extends XWalkResourceClient {
    MyResourceClient(XWalkView view) {
        super(view);
    }

    @Override
    public WebResourceResponse shouldInterceptLoadRequest(XWalkView view, String url) {
        return super.shouldInterceptLoadRequest(view, url);
    }
}

class MyUIClient extends XWalkUIClient {
    MyUIClient(XWalkView view) {
        super(view);
    }

    @Override
    public void onFullscreenToggled(XWalkView view, boolean enterFullscreen) {
        super.onFullscreenToggled(view, enterFullscreen);
    }
}

@Override
public void addContentView(View view, ViewGroup.LayoutParams params) {
    super.addContentView(view, params);
}

@Override
protected void onXWalkReady() {
    mXwalkView = new XWalkView(this, this);
    setContentView(R.layout.main);
    ((FrameLayout) findViewById(R.id.myContainer)).addView(mXwalkView);
    mXwalkView.setResourceClient(new MyResourceClient(mXwalkView));
    mXwalkView.setUIClient(new MyUIClient(mXwalkView));
    mXwalkView.load("http://www.youtube.com/", null);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public Window getWindow() {
    return super.getWindow();
}

@Override
protected void onPause() {
    super.onPause();
    if (mXwalkView != null) {
        mXwalkView.pauseTimers();
        mXwalkView.onHide();
    }
}

@Override
protected void onResume() {
    super.onResume();
    if (mXwalkView != null) {
        mXwalkView.resumeTimers();
        mXwalkView.onShow();
    }
}

@Override
protected void onDestroy() {
    super.onDestroy();
    if (mXwalkView != null) {
        mXwalkView.onDestroy();
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (mXwalkView != null) {
        mXwalkView.onActivityResult(requestCode, resultCode, data);
    }
}

@Override
protected void onNewIntent(Intent intent) {
    if (mXwalkView != null) {
        mXwalkView.onNewIntent(intent);
    }
}
}
