私がエラーを持っている:私も私が知っているすべてのものを試した後削除することができないようこのエラーを解決するにはどのようにこのmakeHttpRequestエラーがありますか?

Error:(102, 53) error: cannot find symbol method makeHttpRequest(String,String,List<NameValuePair>) 

..事前にありがとう助けてください..

これは、アクティビティコードです:

また、私JSONParser.javaは次のとおりです。

どのツールを使用しますか? –

あなたのアクティビティでJSONParserのインポートが間違っています。

はあなた

import org.json.simple.parser.JSONParser;

を削除し、代わりに

import com.example.vikrant.testingv3.JSONParserを追加します。

代わりにyourpackagename.JSONParserをインポートする必要があります。 @ J.Doeすべてのproducts.javaにエラーがあります。それは
