title: Android Accelerometer Accumulation
body: <p>I am getting the accelerometer values continuously (i.e) X and Y values in the run time. My question is that when the values of the accelerometer changes in mobile the corresponding values should be accumulated as per the change. </p>
  
  <p>This is my code :</p>
  
  <pre><code>public class MainActivity extends Activity implements SensorEventListener {
      private SensorManager sensorManager;
  
      private float accumulation_x = 0;
      private float accumulation_y = 0;
      private float accumulation_z = 0;
  
      private TextView acessTextview, angleTextview;
      private float value;
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          findViewById();
  
          sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
          sensorManager.registerListener(this,
                  sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
                  SensorManager.SENSOR_DELAY_NORMAL);
  
      }
  
      public void onAccuracyChanged(Sensor sensor, int accuracy) {
  
      }
  
      public void onSensorChanged(SensorEvent event) {
  
          if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
  
  
  
  
  
              int count = 1;
                      while(count!=0){
  
                          float x = (float) 0.9887777;
                          float y = (float) 0.187359372; 
                          float z = (float) 0.0228636;
  
                  float X_axis = (float) (x + (0.02724095));
                  float Y_axis = (float) (y + (-0.027792556));
                  float Z_axis = (float) (z - (0.105689));
  
                  accumulation_x = accumulation_x + X_axis;
                  accumulation_y = accumulation_y + Y_axis;
                  accumulation_z = accumulation_z + Z_axis;
  
                  value = (y / z);
                  float angle = (float) Math.toDegrees(Math.atan(value));
                  angleTextview.setText("Angle:" + angle);
  
                  acessTextview.setText("accumulation_x  :" + X_axis + "\n"
                          + "accumulation_y :" + Y_axis + "\n"
                          + "accumulation_z  :" + Z_axis);
  
                  count++;
  
                      }
  
          }
  
      }
  
      private void findViewById() {
          // TODO Auto-generated method stub
          acessTextview = (TextView) findViewById(R.id.accessTextview);
          angleTextview = (TextView) findViewById(R.id.angleTextview);
      }
  
  }
