Answer 1

This code works like a charm. However it seems that there are new updates to this as Google made new releases. Key differences are the following:

1. OnMapReadyCallback must be implemented:

   public class InsertMapsActivity extends FragmentActivity implements LocationListener, OnMapReadyCallback

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

   }

2. This code will no longer work:

   // Getting reference to the SupportMapFragment of activity_main.xml
   SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
   
   // Getting GoogleMap object from the fragment
   googleMap = fm.getMap();
   

Instead use this, which calls the callback in #1.

    // 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);

3. References to the googleMap object need be placed in the OnMapReady callback to ensure that the object is initially assigned else null pointer errors would occur:

   @Override 
   public void onMapReady(GoogleMap googleMap) {
           this.googleMap = googleMap;
           // Enabling MyLocation Layer of Google Map
           this.googleMap.setMyLocationEnabled(true);
   googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener()
   {
       @Override
       public void onMapClick(LatLng latLng)
       {
           googleMap.clear();
           googleMap.addMarker(new MarkerOptions().position(latLng).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
           garageLocation = latLng;
       }
   });
   }

Make activity for map and call that where you want location:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".Activity.InsertMapsActivity">

<Button
    android:layout_width="wrap_content"
    android:id="@+id/btn_set_garage_location"
    android:text="set location"
    android:layout_height="wrap_content"/>
<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

java code:

public class InsertMapsActivity extends FragmentActivity implements LocationListener
{

private GoogleMap googleMap;
private LatLng garageLocation;
Button btnSetGarageLocation;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_insert_maps);
    btnSetGarageLocation = (Button) findViewById(R.id.btn_set_garage_location);
    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.

    if (status != ConnectionResult.SUCCESS)
    { // Google Play Services are not available

        int requestCode = 10;
        Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
        dialog.show();

    }
    else
    { // Google Play Services are available

        // Getting reference to the SupportMapFragment of activity_main.xml
        SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

        // Getting GoogleMap object from the fragment
        googleMap = fm.getMap();

        // Enabling MyLocation Layer of Google Map
        googleMap.setMyLocationEnabled(true);

        // Getting LocationManager object from System Service LOCATION_SERVICE
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        // Creating a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Getting the name of the best provider
        String provider = locationManager.getBestProvider(criteria, true);

        // Getting Current Location
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        {
            // TODO: Consider calling

            return;
        }
        Location location = locationManager.getLastKnownLocation(provider);

        if(location!=null){
            onLocationChanged(location);
        }
        locationManager.requestLocationUpdates(provider, 100, 0, this);

        btnSetGarageLocation.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Intent intent = getIntent();
                intent.putExtra("location_lat",garageLocation.latitude);
                intent.putExtra("location_lng",garageLocation.longitude);
                setResult(RESULT_OK,intent);
                finish();
            }
        });
    }

    googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener()
    {
        @Override
        public void onMapClick(LatLng latLng)
        {
            googleMap.clear();
            googleMap.addMarker(new MarkerOptions().position(latLng).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
            garageLocation = latLng;
        }
    });


}

@Override
public void onLocationChanged(Location location)
{

    // Getting latitude of the current location
    double latitude = location.getLatitude();

    // Getting longitude of the current location
    double longitude = location.getLongitude();

    // Creating a LatLng object for the current location
    LatLng latLng = new LatLng(latitude, longitude);

    // Showing the current location in Google Map
    googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

    // Zoom in the Google Map
    googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));

    googleMap.getMaxZoomLevel();

    // Setting latitude and longitude in the TextView tv_location

}

@Override
public void onStatusChanged(String provider, int status, Bundle extras)
{

}

@Override
public void onProviderEnabled(String provider)
{

}

@Override
public void onProviderDisabled(String provider)
{

}
}

in activity:

private int MAP = 2;

Intent intent = new Intent(getApplicationContext(),InsertMapsActivity.class);
                startActivityForResult(intent, MAP);

end of your activity:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    ImageView garageImage = new ImageView(this);
    if (resultCode == Activity.RESULT_OK)
    {

    }

    if(requestCode == MAP)
    {
        double lat = (double) data.getExtras().get("location_lat");
        double lng = (double) data.getExtras().get("location_lng");


    }
}
