    text
    copied!<p>I am trying to include shake functionality in my app. For that i require to intent an activity upon phone shake irrespective of where the user is in the application. Now i placed my sensor code in the application class but in order to intent it requires context. Am i on a right way or is there any other way to achieve this functionality ? Here's my code</p> <pre><code>public class MyApplication extends Application { /* variables for shake detection */ private SensorManager mSensorManager; private float mAccel; // acceleration apart from gravity private float mAccelCurrent; // current acceleration including gravity private float mAccelLast; // last acceleration including gravity @Override public void onCreate(){ /* sensor shake detection */ mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mSensorManager.registerListener(mSensorListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL); mAccel = 0.00f; mAccelCurrent = SensorManager.GRAVITY_EARTH; mAccelLast = SensorManager.GRAVITY_EARTH; } private final SensorEventListener mSensorListener = new SensorEventListener() { public void onSensorChanged(SensorEvent se) { float x = se.values[0]; float y = se.values[1]; float z = se.values[2]; mAccelLast = mAccelCurrent; mAccelCurrent = (float) Math.sqrt((double) (x*x + y*y + z*z)); float delta = mAccelCurrent - mAccelLast; mAccel = mAccel * 0.9f + delta; // perform low-cut filter if(mAccel &gt; 3.0f) { // Toast.makeText(getBaseContext(), "Phone shaked", Toast.LENGTH_SHORT).show(); Intent intent = new Intent(getApplicationContext(),LiveSearchActivity.class); startActivity(intent); } } public void onAccuracyChanged(Sensor sensor, int accuracy) { } }; </code></pre> <p>}</p>
