Question

使用以下代码

从片段DialogFragment链接到网页时崩溃

    DialogInterface.OnClickListener MoreInfoListener = new DialogInterface.OnClickListener() {

    private String url = "http://penny.hpp.io/?p=63";

    public void onClick(DialogInterface dialog, int id) {
        if (checkConnectivity()){
            final Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse(url));
            getActivity().startActivity(intent);
        } 
    }

与崩溃相关的错误如下：

我无法想出这个。请帮忙。它会打开链接，但应用程序会在后台崩溃。因此，当按下后退按钮时，它不会像往常一样返回应用程序。

崩溃链接到网页Android Dev startActivity（Intent.ACTION_VIEW）
