Answer 1

For CONTEXT try initializing it as

this.getApplicationContext()

Answer 2

The Above code had NULLPointerException in case of CONTEXT. Thats why the application was crashing. While showing toast done use this. Use getApplicationContext(). Hope this will solve your problem.

Modified Code:

class Accelerometer extends Service implements AccelerometerListener{ 

@Override
public IBinder onBind(Intent intent) {
// TODO Put your code here
return null;
}

@Override
public void onCreate() {
System.out.println(”start listening”);
// if (AccelerometerManager.isSupported()) { AccelerometerManager.startListening(this);

// }
}

@Override
public void onDestroy() {
System.out.println(”stop listening”);
// if (AccelerometerManager.isListening()) { AccelerometerManager.stopListening();
// }
}

/**
* onShake callback
*/
public void onShake(float force) {
Toast.makeText(getApplicationContext(), “Phone shaked niktilha omha ya 3ammi el7ag: ” + String.valueOf(force), 1000).show(); }

/**
* onAccelerationChanged callback
*/
public void onAccelerationChanged(float x, float y, float z) { System.out.println(”x = “+x+” y = “+y+” z = “+z); }

}
