I am doing a step counter project in an android studio with Nexus5X API29. I need to use sensors for this. I wrote the sensor codes as below, but it still gives 'Sensor not found' error. Is there any way to fix this?
public class MainActivity extends AppCompatActivity implements SensorEventListener {
TextView tv_steps;
SensorManager sensorManager;
Sensor sensor;
boolean running = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate ( savedInstanceState );
setContentView ( R.layout.activity_main );
tv_steps = (TextView) findViewById ( R.id.tv_steps );
sensorManager = (SensorManager) getSystemService ( Context.SENSOR_SERVICE);
}
@Override
protected void onResume() {
super.onResume ();
running = true;
Sensor countSensor = sensorManager.getDefaultSensor ( sensor.TYPE_STEP_COUNTER );
if(countSensor!= null){
sensorManager.registerListener ( this,countSensor,SensorManager.SENSOR_DELAY_UI );
}else {
Log.d ("Main Activity","SENSOR NOT FOUND" );
}
}
@Override
protected void onPause() {
super.onPause ();
running = false;
//if you unregister the hardware will stop detecting steps
}
@Override
public void onSensorChanged(SensorEvent event) {
if (running){
tv_steps.setText ( String.valueOf ( event.values[0] ) );
}
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
}
In Manifest file I also implemnent permission like this:
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" android:required="true"/>
I suggest you test this app on a real device. Usually, emulators don't have certain functionalities like sensors or text-to-speech.
If it still doesn't work, make sure your physical device has step sensors.
