使用action_view意图后Android应用程序崩溃

Question

我有一个奇怪的错误，这是我的代码

String a;
String b;
a="http://website1.com/abcabc1";
String[] separated = a.split("/");
b = separated[3];

String url = "www.website2.com/" + b;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
finish();

我想做的就是在字符串“ abcabc1”中获取“ .com /”之后的值，然后打开一个新网址，即“ www.website2.com/abcabc1”，但我遇到的问题是应用程序崩溃在启动时，我试图发现问题的根源，发现的是，如果我的代码是：

String url = "www.website2.com/";

它可以正常工作，但是如果是这样的话：

String url = "www.website2.com/" + b;

应用程序将崩溃。

注意如果我尝试将字符串url设置为textview文本，则会以正确的形式显示它，但是如果我将其传递给浏览器，则会崩溃。对不起，我的语言不好，谢谢。

您必须"http://"在URL之前进行设置，它将起作用！

String url = "http://www.website2.com/" + b;
