Android Studio:错误:非法字符:'\u2028' [英] Android Studio:error: illegal character: '\u2028'

问题描述

我正在尝试执行 JSONObject 请求:

I am trying to do a JSONObject request:

final String URL = "https://some/url";

// Post params to be sent to the server
HashMap<String, String> params = new HashMap<String, String>();
params.put("param1", param1);

params.put("param2", param2);

params.put("param3", param3);
    
params.put("param4", param4);


JsonObjectRequest req = new JsonObjectRequest(URL, new JSONObject(params), new Response.Listener<JSONObject>() {
    @Override
    public void onResponse(JSONObject response) {
        try {
            VolleyLog.v("Response:%n %s", "läuft");
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.e("Error: ", error.getMessage());
    }
});

// add the request object to the queue to be executed
NetworkController.getInstance().addToRequestQueue(req);

我无法编译项目，因为参数出现语法错误:

I cannot compile the project because I get a syntax error for the params:

错误:(144, 9) 错误:非法字符:'\u2028'

Error:(144, 9) error: illegal character: '\u2028'

我该如何解决?

推荐答案

嗯，删除所有字符并重新重写它们有帮助.太疯狂了..

Well, just deleting all the characters and rewriting them again helped. So crazy..
