java.lang.illegalargumentexception url 中存在非法字符

我想请求网络服务
我的参数是这样的

urlString = http://ip/autodownload/andro.php?key=apps.apk|2|bla.bla.bla

public void getRequest(String Url) {
    Toast.makeText(this, "Tambah Data " + Url + " ", Toast.LENGTH_SHORT).show();
    HttpClient client = new DefaultHttpClient();
    HttpGet request = new HttpGet(urlString);
    try {
        System.out.println("tes");
        HttpResponse response = client.execute(request);
        Toast.makeText(this,request(response),Toast.LENGTH_SHORT).show();
        String res = EntityUtils.toString(response.getEntity());
        System.out.println(res);
        Update(res);
    } catch (Exception ex) {
        Toast.makeText(this, "Gagal Konek Server !", Toast.LENGTH_SHORT).show();
    }       
}

如果我在浏览器中运行，那就没问题，但是当我在 Android 中运行时，会出现这样的错误

我尝试过 Urlencoding 和替换字符，但它不起作用
我该怎么办？谢谢
*SOLVED
我在 urlString 中替换字符，如下所示：

urlString+="?key="+appName.trim().replace(".", "%2E")+"|2|".trim().replace("|", "%7C")+packageName.trim().replace(".", "%2E");

并且工作正常:)

尝试对您的 URL 进行编码

String link="http://example.php?string1="+URLEncoder.encode(string1)+"&string2="+URLEncoder
.encode(string2)+"&string3="+URLEncoder.encode(string3)+"&string4="+URLEncoder.encode(string4)+"";
