Use services.. Do something like that-

public class ServicesDemo extends Activity implements OnClickListener {
 private static final String TAG = "ServicesDemo";
 Button buttonStart, buttonStop,buttonNext;

 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  buttonStart = (Button) findViewById(R.id.buttonStart);
  buttonStop = (Button) findViewById(R.id.buttonStop);
  buttonNext = (Button) findViewById(R.id.buttonNext);

  buttonStart.setOnClickListener(this);
  buttonStop.setOnClickListener(this);
  buttonNext.setOnClickListener(this);
 }

 public void onClick(View src) {
  switch (src.getId()) {
  case R.id.buttonStart:
   Log.d(TAG, "onClick: starting srvice");
   startService(new Intent(this, MyService.class));
   break;
  case R.id.buttonStop:
   Log.d(TAG, "onClick: stopping srvice");
   stopService(new Intent(this, MyService.class));
   break;
  case R.id.buttonNext:
   Log.d(TAG, "onClick: next Page");
   Intent intent=new Intent(this,NextPage.class);
   startActivity(intent);
   break;
  }
