android studio调用百度SDK进行定位，老返回错误码62，怎么回事

主方法

package demo.baidudemo;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;

public class MapsActivity extends Activity {

public LocationClient mLocationClient = null;
private LocationClientOption.LocationMode tempMode = LocationClientOption.LocationMode.Hight_Accuracy;
private String tempcoor="gcj02";
private TextView textView1;
private Button button;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.this_one);
    mLocationClient = ((LocationApplication)getApplication()).mLocationClient;
    textView1= (TextView) findViewById(R.id.textView1);
    button= (Button) findViewById(R.id.startLocation);
    ((LocationApplication)getApplication()).mLocationResult = textView1;
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            InitLocation();
            mLocationClient.start();
        }
    });

}

private void InitLocation(){
    LocationClientOption option = new LocationClientOption();
    option.setOpenGps(true);
    option.setLocationMode(tempMode);//设置定位模式
    option.setCoorType(tempcoor);//返回的定位结果是百度经纬度，默认值gcj02
    int span=10000;
    option.setScanSpan(span);

    //设置发起定位请求的间隔时间为5000ms
    option.setIsNeedAddress(true);
    mLocationClient.setLocOption(option);
}
@Override
protected void onStop() {

    mLocationClient.stop();
    super.onStop();
}

}

}

谁能帮我看看~感激不尽

如果代码本身没有问题，很有可能是签名的问题
集成百度地图失败，最容易犯的错误就是签名错误，Android studio的debug运行的签名就要保证是去百度后台申请key的时候的签名
debug的签名可以在module setting里面设置
