Getting Current Places by Using Places API

You can get the current location and local places of user by using the Google Places API.

Ar first, you should call the PlaceDetectionApi.getCurrentPlace() method in order to retrieve local business or other places. This method returns a PlaceLikelihoodBuffer object which contains a list of PlaceLikelihood objects. Then, you can get a Place object by calling the PlaceLikelihood.getPlace() method.

Important: You must request and obtain the ACCESS_FINE_LOCATION permission in order to allow your app to access precise location information.

private static final int PERMISSION_REQUEST_TO_ACCESS_LOCATION = 1;

private TextView txtLocation;
private GoogleApiClient googleApiClient;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_location);

    txtLocation = (TextView) this.findViewById(R.id.txtLocation);
    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Places.GEO_DATA_API)
            .addApi(Places.PLACE_DETECTION_API)
            .enableAutoManage(this, this)
            .build();

    getCurrentLocation();
}

private void getCurrentLocation() {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        Log.e(LOG_TAG, "Permission is not granted");

        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},PERMISSION_REQUEST_TO_ACCESS_LOCATION);
        return;
    }

    Log.i(LOG_TAG, "Permission is granted");
    
    PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi.getCurrentPlace(googleApiClient, null);
    result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
        @Override
        public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
            Log.i(LOG_TAG, String.format("Result received : %d " , likelyPlaces.getCount() ));
            StringBuilder stringBuilder = new StringBuilder();

            for (PlaceLikelihood placeLikelihood : likelyPlaces) {
                stringBuilder.append(String.format("Place : '%s' %n",
                        placeLikelihood.getPlace().getName()));
            }
            likelyPlaces.release();
            txtLocation.setText(stringBuilder.toString());
        }
    });
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_TO_ACCESS_LOCATION: {
            // If the request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                getCurrentLocation();
            } else {
                // Permission denied, boo!
                // Disable the functionality that depends on this permission.
            }
            return;
        }

        // Add further 'case' lines to check for other permissions this app might request.
    }
}
