Google puts autocompletes Android API: restrictions don't work

Question

I define my boundaries as follows:

private static final LatLngBounds BOUNDS_CHENNAI = new LatLngBounds( new LatLng(12.8339547, 80.0817007), new LatLng(13.2611661, 80.33632279999999)); // Chennai city bounds. 

Create the Goolge API client as follows:

 mGoogleApiClient = new GoogleApiClient.Builder(this) .enableAutoManage(this,this) .addApi(Places.GEO_DATA_API) .addConnectionCallbacks(this) .build(); 

And using these boundaries in the adapter, do the following:

 PendingResult<AutocompletePredictionBuffer> results = Places.GeoDataApi .getAutocompletePredictions(mGoogleApiClient, constraint.toString(), mBounds, mPlaceFilter); 

According to the documentation, I should only return to me a place in the city of Chennai, but it will return me a place from around the world.

eg. When I type “Sola”, it returns the “Sola road” of Ahmedabad instead of showing consistent results within.

Answer 1

I have the same problem with limitations in android. I tried everything and can not solve the problem.

We are looking for other web pages, I found this in the documentation for javascript when trying to set boundaries in the area:

The results are biased to the side, but not limited to, the places contained within these boundaries.

It seems that the api documentation for android sites is not complete. We will have to wait.

I found a primitive workaround if you need to show the results of a specified country or neighboring countries:

 private ArrayList<PlaceAutocomplete> getAutocomplete(CharSequence constraint) { if (mGoogleApiClient.isConnected()) { // Submit the query to the autocomplete API and retrieve a PendingResult that will // contain the results when the query completes. PendingResult<AutocompletePredictionBuffer> results = Places.GeoDataApi .getAutocompletePredictions(mGoogleApiClient, constraint.toString(), mBounds, mPlaceFilter); AutocompletePredictionBuffer autocompletePredictions = results .await(60, TimeUnit.SECONDS); final Status status = autocompletePredictions.getStatus(); if (status.isSuccess()) { Log.i(LOG_TAG, "Query completed. Received " + autocompletePredictions.getCount() + " predictions."); // Copy the results into our own data structure, because we can't hold onto the buffer. // AutocompletePrediction objects encapsulate the API response (place ID and description). Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator(); ArrayList<PlaceAutocomplete> resultList = new ArrayList<>(autocompletePredictions.getCount()); while (iterator.hasNext()) { AutocompletePrediction prediction = iterator.next(); // Get the details of this prediction and copy it into a new PlaceAutocomplete object. String data = prediction.getDescription(); // here we manually checking whether description contains our needed country(ies) if (predictionIsInNeededCountry(data)) { resultList.add(new PlaceAutocomplete(prediction.getPlaceId(), prediction.getDescription(), prediction.getPrimaryText(mCharacterStyle), prediction.getSecondaryText(mCharacterStyle), prediction.getFullText(mCharacterStyle))); } } } else { Toast.makeText(mContext, "Error contacting API: " + status.toString(), Toast.LENGTH_SHORT).show(); Log.e(LOG_TAG, "Error getting autocomplete prediction API call: " + status.toString()); autocompletePredictions.release(); return null; } // Release the buffer now that all data has been copied. autocompletePredictions.release(); return resultList; } Log.e(LOG_TAG, "Google API client is not connected for autocomplete query."); return null; } private boolean predictionIsInNeededCountry(String data) { // here you can add countries (in different languages if you want) // also you can try get current country programmatically with use of Geocoder if (data.contains("Ukraine") || data.contains("") || data.contains("ї")) { return true; } return false; } 

For borders, I use the current coordinates (current latitude and longitude for the southwest and for the northeast).

I also implemented another solution:

• Get Predictions
• Get information about each forecast (you can pass an array to immediately get all the points).
• Compare the coordinates of the point with the current and sort them from the nearest to the farthest.
• Show sorted by distance.

It seems to work more accurately, but requires additional queries and calculations.
In my case, I only need results from two countries, so I get the first simpler solution.
