このコードに、加速度センサーの感度を上げ、電話を振ったときの画面の明るさを上げるためのいくつかの指示を実装したいと思います。

sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
sensorManager.registerListener(this,         sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
lastUpdate = System.currentTimeMillis();

@Override
public void onSensorChanged(SensorEvent event) {
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {                                     getAccelerometer(event);
}
}   
private void getAccelerometer(SensorEvent event) {
super.onResume();
float[] values = event.values;
// Movement
float x = values[0];
float y = values[1];
float z = values[2];
float accelationSquareRoot = (x * x + y * y + z * z)
/ (SensorManager.GRAVITY_EARTH * SensorManager.GRAVITY_EARTH);
long actualTime = System.currentTimeMillis();
if (accelationSquareRoot >= 2) //
{
if (actualTime - lastUpdate < 200) {            
return;
}           
lastUpdate = actualTime;            
Toast.makeText(this, "Device was shuffed", Toast.LENGTH_SHORT).show();  
if (mMediaPlayer.isPlaying() == false){ 
mMediaPlayer.start();               
}
}
}

int stretch = 50;
int boundary = 5;

float x = values[0];
float y = values[1];
float z = values[2];

x *= stretch;
y *= stretch;
z *= stretch;

if (x > 5 || x < -5) 
   x = 0;
if (y > 5 || y < -5) 
   y = 0;
if (z > 5 || z < -5) 
   z = 0;

非常に基本的なフィルター

画面の明るさに関する限り：

private void setBrightness(int brightness) {  
try {  
  IHardwareService hardware = IHardwareService.Stub.asInterface(  
  ServiceManager.getService("hardware"));  
  if (hardware != null) {  
    hardware.setScreenBacklight(brightness);  
  }  
} catch (RemoteException doe) {            
  }          
}
