How to use Gyroscope Sensor in Android

This is a simple example to create an app using Gyroscope Sensor. Here you will learn basics of Gyroscope Sensor.

Follow these steps:

1. Create an android project.
2.Create a Main activity (MainGyroscope.java)

import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;

public class MainGyroscope extends Activity implements SensorEventListener {
    private SensorManager mgr;
    private Sensor gyro;
    private TextView text;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mgr = (SensorManager) this.getSystemService(SENSOR_SERVICE);
        gyro = mgr.getDefaultSensor(Sensor.TYPE_GYROSCOPE);
        text = (TextView) findViewById(R.id.text);
    }

    @Override
    protected void onResume() {
        mgr.registerListener(this, gyro, SensorManager.SENSOR_DELAY_GAME);
      super.onResume();
    }

    @Override
    protected void onPause() {
        mgr.unregisterListener(this, gyro);
      super.onPause();
    }

  public void onAccuracyChanged(Sensor sensor, int accuracy) {

  }

  public void onSensorChanged(SensorEvent event) {
    String msg = "0: " + event.values[0] + "\n" +
        "1: " + event.values[1] + "\n" +
        "2: " + event.values[2] + "\n";
    text.setText(msg);
    text.invalidate();
  }
}

3.  Create the resource res/layout/main.xml and paste following code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"  android:layout_height="fill_parent" >
  <TextView  android:id="@+id/text" android:textSize="20sp"
    android:layout_width="fill_parent"  android:layout_height="wrap_content" />
</LinearLayout>

 Thats it.
Note: You can run this apps only on live devices. But before installing this apps on your mobile, Please check the list of sensors running on you mobile.
