解决 java.lang.RuntimeException: Method i in android.util.Log not mocked. See http://g.co/androidstudi

1. 原因

Android SDK 中测试一个 Json 不会消耗哪些本不必要的资源.

2. 解决

添加包

    testImplementation 'org.json:json:20201115'

自定义一个 JsonUtils 文件

package com.ykenan.alipay.util;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

public class JsonUtils {
    
    

    public Map<String, Object> parse(String jsonStr) {
    
    
        Map<String, Object> result = null;
        if (null != jsonStr) {
    
    
            try {
    
    
                JSONObject jsonObject = new JSONObject(jsonStr);
                result = parseJSONObject(jsonObject);
            } catch (JSONException e) {
    
    
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } // if (null != jsonStr)
        return result;
    }

    private Object parseValue(Object inputObject) throws JSONException {
    
    
        Object outputObject = null;
        if (null != inputObject) {
    
    
            if (inputObject instanceof JSONArray) {
    
    
                outputObject = parseJSONArray((JSONArray) inputObject);
            } else if (inputObject instanceof JSONObject) {
    
    
                outputObject = parseJSONObject((JSONObject) inputObject);
            } else if (inputObject instanceof String || inputObject instanceof Boolean || inputObject instanceof Integer) {
    
    
                outputObject = inputObject;
            }
        }
        return outputObject;
    }

    private List<Object> parseJSONArray(JSONArray jsonArray) throws JSONException {
    
    
        List<Object> valueList = null;
        if (null != jsonArray) {
    
    
            valueList = new ArrayList<>();
            for (int i = 0; i < jsonArray.length(); i++) {
    
    
                Object itemObject = jsonArray.get(i);
                if (null != itemObject) {
    
    
                    valueList.add(parseValue(itemObject));
                }
            } // for (int i = 0; i < jsonArray.length(); i++)
        } // if (null != valueStr)
        return valueList;
    }

    private Map<String, Object> parseJSONObject(JSONObject jsonObject) throws JSONException {
    
    
        Map<String, Object> valueObject = null;
        if (null != jsonObject) {
    
    
            valueObject = new HashMap<>();
            Iterator<String> keys = jsonObject.keys();
            while (keys.hasNext()) {
    
    
                String keyStr = keys.next();
                Object itemObject = jsonObject.opt(keyStr);
                if (null != itemObject) {
    
    
                    valueObject.put(keyStr, parseValue(itemObject));
                } // if (null != itemValueStr)
            } // while (keyStr.hasNext())
        } // if (null != valueStr)
        return valueObject;
    }
}

测试

        JsonUtils jsonUtils = new JsonUtils();
        System.out.println(jsonUtils.parse(jsonData).get("name"));
