私のJavaプログラムを実行した後、pubnubから正しく公開されたデータを取得したが、後で正しくない

Question

IoTモデムのボタンを押してデータを取得しているjavaファイルを作成しました。 IoTデバイスはPubNub上にプロトコルデータを公開しており、これを購読した後でPubNubからデータを取得しています。

受信したデータは、ASCII形式の16進値です。

私はプロトコルデータを単一の文字列として取得し、char配列に変換してから、配列から配列の一部を取り出して10進数値に変換しています。

プログラムの実行直後に正しいデータを取得していますが、後でデータが正しくない。私はこれを実行すると、

    String CHANNEL = "IOT1"; 
    Pubnub pn = new Pubnub(PUB_KEY,SUB_KEY); 

    String receivedData = new String(); //to store the subscribed data 
    char[] receivedDataInArray = new char[50]; //to store the converted string

} 

のIoTモデムのボタンを押した後、私は正しいデータを取得しています。しかし、私は、もう一度だけデバイスIdをとイベントカウントを押した場合：ここで

は私の全体のコードです異なってくる。ここで

私の出力です：プロトコル・データから実行ここで

167303080003063001020001 
DATA :-167303080003063001020001 
Message length : 24 
167303080003063001020001 
device ID:--23541363 
***Received data from device*** 

Device id : 23541363 
Product Id: 3 
Time Hour: 6 
Time Minutes: 30 
Date Day: 1 
Date Month: 2 
Event Count: 4097 

、後の第二の時間を取得している

1回目

実行後デバイスは両方の出力に対して同じです。

コールバック（）に問題はありますか？

Answer 1

デバイスIDとイベントカウンタの値が以前の値と現在の値を使用していて、プロセス変換後に大きな値が割り当てられていました。

successCallback（）内のすべての変数を宣言すると、このブロックを呼び出すたびに、プロセス全体の実行後にすべての変数の値がゼロになります。すべて正しい値を持ちます。

public void successCallback(String arg0, Object arg1) { 

    int deviceId = 0; 
    int functionCode = 0; 
    int productId =0; 
    int timeHour = 0; 
    int timeMin = 0; 
    int dateDay = 0; 
    int dateMonth = 0; 
    int eventCount = 0; 

    System.out.println(arg1); 
    receivedData = (String)arg1; //subscribed data stored 
    System.out.println("DATA :-" + receivedData); 
    System.out.println("Message length : "+receivedData.length()); 

    for(int i=0; i<receivedData.length(); i++) { 
     receivedDataInArray[i] = receivedData.charAt(i);  //Received data converted into array 
    } 
    . . . . 
    . . . .
