在签署我的应用程序时，googleapi会出现无法工作的地方

Question

我正在使用这个链接：

private static final String PLACES_SEARCH_URL = "htt`ps://maps.googleapis.com/maps/api/place/search/json?";`

搜索地点，一切都很好。

我已经从控制台生成了一个服务器密钥。developers.google.com/project/

但当我在申请表上签字时，我却无法获得名额。

是因为我的申请名称吗？

GoogleHeaders headers = new GoogleHeaders();
headers.setApplicationName("**myApplicationName**");

我应该在这里放什么？

这是示例代码：

public class GooglePlaces {
    /** Global instance of the HTTP transport. */
    private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
    // Google API Key
    private static final String API_KEY = "MY SERVER API KEY";
    // Google Places serach url's
    private static final String PLACES_SEARCH_URL = "https://maps.googleapis.com/maps/api/place/search/json?";
    //private static final String PLACES_TEXT_SEARCH_URL = "https://maps.googleapis.com/maps/api/place/search/json?";
    private static final String PLACES_DETAILS_URL = "https://maps.googleapis.com/maps/api/place/details/json?";
    private double _latitude;
    private double _longitude;
    private double _radius;
    /**

     * @return list of places
     * */
    public PlacesList search(double latitude, double longitude, double radius, String types)
            throws Exception {
        this._latitude = latitude;
        this._longitude = longitude;
        this._radius = radius;
        try {
            HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
            HttpRequest request = httpRequestFactory
                    .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
            request.getUrl().put("key", API_KEY);
            request.getUrl().put("location", _latitude + "," + _longitude);
            request.getUrl().put("radius", _radius); // in meters
            request.getUrl().put("sensor", "false");
            if(types != null)
                request.getUrl().put("types", types);
            PlacesList list = request.execute().parseAs(PlacesList.class);
            // Check log cat for places response status
            Log.d("Places Status", "" + list.status);
            return list;
        } catch (HttpResponseException e) {

            return null;
        }
    }
    /**

    public PlaceDetails getPlaceDetails(String reference) throws Exception {
        try {
            HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
            HttpRequest request = httpRequestFactory
                    .buildGetRequest(new GenericUrl(PLACES_DETAILS_URL));
            request.getUrl().put("key", API_KEY);

            throw e;

    public static HttpRequestFactory createRequestFactory(

                request.setHeaders(headers);
                JsonHttpParser parser = new JsonHttpParser(new JacksonFactory());
                request.addParser(parser);

Answer 1

您应该在下面链接android应用程序中的google place api：-

http://wptrafficanalyzer.in/blog/selecting-google-place-from-autocompletetextview-and-marking-in-google-map-android-api-v2/

这将对地图v2有很大帮助。

Answer 2

在保留使用谷歌地图API 的Serializable类后解决了问题

-keepnames class * implements java.io.Serializable
-keepclassmembers class * implements java.io.Serializable {
     static final long serialVersionUID;
     private static final java.io.ObjectStreamField[] serialPersistentFields;
     !static !transient <fields>;
     !private <fields>;
     !private <methods>;
     private void writeObject(java.io.ObjectOutputStream);
     private void readObject(java.io.ObjectInputStream);
     java.lang.Object writeReplace();
     java.lang.Object readResolve();

}
