Question

我正在开发一个Android库，我在我的Test项目中添加了我的lib，现在我有一个错误，无法完成我的测试：

Could not find method org.json.JSONObject.put, referenced from method com.ldm.JsonBuilder.jsonbuilder

Process: , PID: 31181
java.lang.NoSuchMethodError: org.json.JSONObject.put

这是我的傻瓜：

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/httpcore-4.4.4.jar')
    compile files('libs/json.jar')
    compile 'org.json:json:20141113'
}

这是我的代码的一部分：

   /* Parsing of hash map */
    for (Map.Entry<String, ArrayList<String>> tr : rh.entrySet()) {

        try {
            /* Object that contains URL */
            JSONObject TraceUrl = new JSONObject();
            /* Object that contains nodes for each URL */
            JSONObject TraceNodes = new JSONObject();

            TraceUrl.put("url", tr.getKey());
            TraceUrl.put("nodes", tr.getValue());
            trace.put(TraceUrl);
        } catch (JSONException e) {
            System.out.println("Exception: " + e.toString());
        }

我如何解决它？

Answer 1

您似乎正在导入某种没有put()方法的外部json库。

put()的JSONObject是＆＃34;内置＆＃34;对于Android，你不需要任何额外的库。

import org.json.JSONObject;

JSONObject jsonObject = new JSONObject();
jsonObject.put("key", "value");

这样可行。

Java.lang.NoSuchMethodError：org.json.JSONObject.put
