How to get my current location in android maps?

Question

Actually my problem is I am not getting current location latitude and longitude I tried so many ways.I know that this question already asked in SO I tried that answers also still I didn't get answer.Please help me.

I want to get my current location in Map and set it in the location variable

This is my code:

- onCreate Method

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_your_location);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    infoTextView = (TextView) findViewById(R.id.infoTextView);
    requestKorsaButton = (Button) findViewById(R.id.requestKorsa);

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    provider = locationManager.getBestProvider(new Criteria(), true);
    if(provider == null) {
        Toast.makeText(this, "No Location for you", Toast.LENGTH_SHORT).show();
    }

    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
                this,
                new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_FINE_LOCATION},
                PERMISSION_LOCATION_REQUEST_CODE);
    }
    locationManager.requestLocationUpdates(provider, 400, 1, this);
}

- onMapReady method

   @Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
                this,
                new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_FINE_LOCATION},
                PERMISSION_LOCATION_REQUEST_CODE);
    }
    mMap.setMyLocationEnabled(true);

    location = locationManager.getLastKnownLocation(provider);
    if (location != null) {
        updateLocation(location);
    }

}

我只是通过以下示例添加当前位置： https ： //github.com/googlemaps/android-samples （请参阅我当前位置的一部分）并将此示例项目中的一个文件添加到我的应用中：“PermissionUtils.java “

This problem was happening because I was trying to run my application in the emulator but when I was running in my device, it works. Thanks...
