我几天来一直在研究这个问题,并且无法解决这个问题.我在使用WebViews时遇到的问题是,当我加载vimeo视频时,它会因以下错误而失败:
java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

现在奇怪的是,这种情况发生在Anroid 7.0上并没有比Android 4.4更低(没有用于5.0或6.0的物理设备进行测试).

public class FragmentWebView extends Fragment{
protected WebView myWebView;
private String title, url, message;
private boolean isOffline;
View vWebView;
ViewFinder viewPullDowns;
SwipeRefreshLayout srlWebview;
protected void setTitle(String title) {
this.title = title;
}
protected void setUrl(String url) {
this.url = url;
}
@Nullable
