Android - Tracking using GPS, getMap deprecated

Question

public class LocationActivity extends FragmentActivity implements
        LocationListener,
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {

    private static final String TAG = "LocationActivity";
    private static final long INTERVAL = 1000 * 60 * 1; //1 minute
    private static final long FASTEST_INTERVAL = 1000 * 60 * 1; // 1 minute
    Button btnFusedLocation;
    TextView tvLocation;
    LocationRequest mLocationRequest;
    GoogleApiClient mGoogleApiClient;
    Location mCurrentLocation;
    String mLastUpdateTime;
    GoogleMap googleMap;

    protected void createLocationRequest() {
        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(INTERVAL);
        mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (!isGooglePlayServicesAvailable()) {
            finish();
        }
        createLocationRequest();
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

        setContentView(R.layout.activity_location_google_map);
        SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        googleMap = fm.getMap();
        googleMap.getUiSettings().setZoomControlsEnabled(true);
    }
}

I'm trying to track using gps and plot the location on a map. I tried the above code but getMap is deprecated and I'm getting a screen on my phone. Could someone help me how to solve this issue?

GetMap() is deprecated.You need to implement OnMapReadyCallback in your class

public class LocationActivity extends FragmentActivity implements
    LocationListener,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener, OnMapReadyCallback  {

And override the: onMapReady() function

@Override
public void onMapReady(GoogleMap map) {
    googleMap = map;
    googleMap.getUiSettings().setZoomControlsEnabled(true);
    //add code here
}

Also in your code add:

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
fm.getMapAsync(this);

And in layout:

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

I've tried this, but it says "Attempt to invoke getMapAsync(..) on null object reference. – Jab Apr 07 '17 at 20:17
did you call `fm.getMapAsync(this);` ? – rafsanahmad007 Apr 07 '17 at 20:18
yes, MapFragment mapFragment = (MapFragment) getFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this); – Jab Apr 07 '17 at 20:20

use: `SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map); fm.getMapAsync(this); ` – rafsanahmad007 Apr 07 '17 at 20:21
