放置Google Api-自动完成

Question

This is a bit weird, I followed the Google places API to add autocomplete for my android app. Google Places API request denied for Android autocomplete, even with the right api key. I even tried to check with the JSON Client and requested both GET/POST still same error because I'm sure my code follows the integration for google api autocomplete accordingly. I have not found any solution that resolves the error. Some answers suggest removing sensor with place_id. I don't know. Kindly explain a solution or suggestion that would help me to get the autocomplete working fine.

https://maps.googleapis.com/maps/api/place/autocomplete/json/?sensor=false&key=API_KEY&components=country=us&input=california

Answer 1

Hi brother use like this try this url with your api key: https://maps.googleapis.com/maps/api/place/autocomplete/json?sensor=true&key= api key&language=en&input=kir

Its working bro.

Answer 2

It will work in android app only. Don't try it in REST client. Instead try debugging your app to see response.

    }
};

  }

its working ... do like this create server key and allow all then in android use autoacmpltere Create a server key in google api console and allow all then enable google feture in permissions its working bro try this ....

Answer 4

So jaswinder the changes I need to make as I assumed is replace the sensor with place_id and my try catch should also change to look like your code snippet;

try {

        // Create a JSON object hierarchy from the results

        JSONObject jsonObj = new JSONObject(jsonResults.toString());

        JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");

        // Extract the Place descriptions from the results

        resultList = new ArrayList<String>(predsJsonArray.length());

        for (int i = 0; i < predsJsonArray.length(); i++) {

            resultList.add(predsJsonArray.getJSONObject(i).getString(

            "description"));

        }

    } catch (JSONException e) {

        Log.e(TAG, "Cannot process JSON results", e);

    }

    return resultList;

Then I can create server key as you explained, I should be good to go then. Thanks

Hey guys now the autocomplete is working Jaswinder I just added place_id where you commented it out and wala! it works like a charm.

Hope this code helps someone. I used the Key for browser application and enabled both Places api and Goople map api in the console.

private class PlacesAutoCompleteAdapter extends ArrayAdapter<String>
        implements Filterable {
    private ArrayList<String> resultList;

    public PlacesAutoCompleteAdapter(Context context, int textViewResourceId) {
        super(context, textViewResourceId);
    }

    @Override
    public int getCount() {
        return resultList.size();
    }

    @Override
    public String getItem(int index) {
        return resultList.get(index);
    }

    @Override
    public Filter getFilter() {
        Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults filterResults = new FilterResults();
                if (constraint != null) {
                    // Retrieve the autocomplete results.
                    resultList = autocomplete(constraint.toString());

                    // Assign the data to the FilterResults
                    filterResults.values = resultList;
                    filterResults.count = resultList.size();
                }
                return filterResults;
            }

            @Override
            protected void publishResults(CharSequence constraint,
                    FilterResults results) {
                if (results != null && results.count > 0) {
                    notifyDataSetChanged();
                } else {
                    notifyDataSetInvalidated();
                }
            }
        };
        return filter;
    }
}

// Get array list of addresses
private ArrayList<String> autocomplete(String input) {

    ArrayList<String> resultList = null;

    HttpURLConnection conn = null;

    StringBuilder jsonResults = new StringBuilder();

    try {
        StringBuilder sb = new StringBuilder(PLACES_API_BASE

        sb.append("?sensor=true&key="

        + API_KEY);

        // for current country.Get the country code by SIM

        // If you run this in emulator then it will get country name is
        // "us".

        String cName = getCountryCode();

        if (cName != null) {
            countryName = cName;
        } else {
            countryName = "za";
        }
        sb.append("&components=country:" + countryName);
        sb.append("&input=" + URLEncoder.encode(input, "utf8"));

        URL url = new URL(sb.toString());

        conn = (HttpURLConnection) url.openConnection();

        InputStreamReader in = new InputStreamReader(conn.getInputStream());

        // Load the results into a StringBuilder

        int read;

        while ((read = in.read(buff)) != -1) {

            jsonResults.append(buff, 0, read);

        }

    } catch (MalformedURLException e) {

        Log.e(TAG, "Error processing Places API URL", e);

        return resultList;

    } catch (IOException e) {

        Log.e(TAG, "Error connecting to Places API", e);

        return resultList;

    } finally {

        if (conn != null) {

            conn.disconnect();

        }

    }

    try {

        // Create a JSON object hierarchy from the results

        JSONObject jsonObj = new JSONObject(jsonResults.toString());

        JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");

        // Extract the Place descriptions from the results

        resultList = new ArrayList<String>(predsJsonArray.length());

        for (int i = 0; i < predsJsonArray.length(); i++) {

            resultList.add(predsJsonArray.getJSONObject(i).getString(

            "description"));

            resultList.add(predsJsonArray.getJSONObject(i).getString(
                    "place_id"));

        }

    } catch (JSONException e) {

        Log.e(TAG, "Cannot process JSON results", e);

    }

    return resultList;

}
