android值上载数据库与json

我发明了磁场传感器。此代码给出x y z事件值、算术平均值和SQRTx^2+y^2+z^2 我必须上传这些值。如何使用json或其他方式上载这些值。这是我的密码

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_main);
    SensingTextView tv = new SensingTextView(this);
    SensorManager sm = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    sm.registerListener(tv,
            sm.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD),
            SensorManager.SENSOR_DELAY_UI);


    setContentView(tv);



}


public class SensingTextView extends TextView implements SensorEventListener {
    public SensingTextView(Context context) {
        super(context);
    }

    @Override
    public void onSensorChanged(SensorEvent event) {



        String newstr = String.format("x: %f\ny:%f\nz:%f\n\nSQRTx^2+y^2+z^2: %f\n\nArithmeticAvg: %f",
                new Object[] { event.values[0],event.values[1],event.values[2],Math.sqrt(((event.values[0] * event.values[0])
                                + (event.values[1] * event.values[1]) + (event.values[2] * event.values [2]))),
                        ((event.values[0] + event.values[1] + event.values[2])/3)
                         } );

        setText(newstr);

    }

如果要将值上载到mySql数据库，请执行以下步骤：

1-在服务器上创建包含所需字段的表

2-编写php或任何服务器端代码以从客户端获取值

3-在android中实现代码
