我有一個奇怪的錯誤，這裏是我的代碼的Android應用程序崩潰的意圖
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();
我想做的事情後的.com /越來越值了」，在字符串‘這是abcabc1什麼’和然後打開一個新的網址「www.website2.com/abcabc1」，但是我遇到的問題是應用程序在啓動時崩潰。我試圖發現問題的根源，我發現如果我的代碼是：
String url = "www.website2.com/";
這將工作沒有任何問題，但如果它是這樣的：
String url = "www.website2.com/" + b;
應用程序將崩潰。
注意如果我嘗試將字符串url設置爲textview文本，它將以正確的格式顯示它，但是如果我將它傳遞給瀏覽器，它會崩潰。對不起，我的可憐的語言，並提前感謝。
