android 传递给ｓｅｒｖｉｃｅ数据空指针问题

74行出错　，nullpointException，帮我解答感激不尽，我想把这个数据传给ｓｅｒｖｉｃｅ
public class pdrActivity extends Activity implements View.OnClickListener{
private Button wifi_btn,pdr_btn,photo_btn,other_btn;

};

}
下面的是我的ｓｅｒｖｉｃｅ
public class pdrService extends Service implements SensorEventListener{
float[] inf=new float[5];
float[] infmation={0,0,0};

    super.onCreate();
    if (infmation!=null){
        inf[0]=1;
        inf[1]=1;
        inf[2]=1;
    }
    else{
        inf[0]=2;
        inf[1]=2;
        inf[2]=2;

    }

    thread=new proceedThread();
    thread.start();

}

@Nullable
