您好我正在尝试使用json解析将一些数据发送到服务器但是活动正在崩溃并且导致了 java.lang.IllegalArgumentException：意外的URL
这是我的活动代码，我正在评论我得到错误的行。

答案 0 :(得分：2)
您的错误来自OkHttp。
如果您搜索错误消息，您可以看到OkHttp生成它的位置：
https://github.com/square/okhttp/blob/master/okhttp/src/main/java/okhttp3/Request.java#L142
HttpUrl parsed = HttpUrl.parse(url);
if (parsed == null) throw new IllegalArgumentException("unexpected url: " + url);
return url(parsed);
这表示您的网址无效。正如您对问题的评论所指出的那样：>http://192.168.2.20:8080/jagteraho/batteryStatus/save不是有效的网址。
您需要删除>。
