A method for waiting for sensor data

Question

I have a class which initiates a sensor listener when it is started. This listener writes the latest sensor value to a variable when an event is triggered. The class goes on

I am using Handler for exactly same situation.

Handler handler = new Handler();
handler.post(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                try {
                    x1.setText(String.valueOf(sensors.getValueAccX()));
        Log.d("Sensors", String.valueOf(sensors.getValueAccZ()));//using persoanl methods that are not shown here
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (Exception e) {
                    Toast.makeText(ClientSideActivity.this,
                            "Server is not running", Toast.LENGTH_LONG).show();
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                // TODO Auto-generated method stub

                handler.postDelayed(this, 100);
            }

        });
