打开 pdf 时出现 MUPDF UnsupportedOperationException

我正在将 MUPDF 用于 Android 项目，但一些 Android 用户遇到了问题。我得到的报告如下：

 java.lang.UnsupportedOperationException: Not supported

此异常发生在这一行：

public View getSelectedView() {
    throw new UnsupportedOperationException("Not supported");
}

我不知道如何解决这个问题，有人可以帮忙吗？谢谢！

刚刚修复：

public View getSelectedView() {
//throw new UnsupportedOperationException("Not supported");

return null;
