Question

我正在尝试使用适用于Android的GoogleMap＆api api在我的应用中创建地方搜索功能。我想填写AutoComplete TextView作为用户键入地点的名称。但是我在调用urlConnection.connect();声明时得到了这个例外：

javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0xb911cd50: Failure in SSL library, usually a protocol error
error:1407743E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert inappropriate fallback (external/openssl/ssl/s23_clnt.c:765 0xae688edd:0x00000000)

以下是我使用的代码：

private String downloadUrl(String strUrl) throws IOException {
    String data = "";
    InputStream iStream = null;
    HttpURLConnection urlConnection = null;
    try {
        URL url = new URL(strUrl);

        // Creating an http connection to communicate with url
        urlConnection = (HttpURLConnection) url.openConnection();

        // Connecting to url
        urlConnection.connect();

        // Reading data from url
        iStream = urlConnection.getInputStream();

        BufferedReader br = new BufferedReader(new InputStreamReader(iStream));

        StringBuffer sb = new StringBuffer();

        String line = "";
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }

        data = sb.toString();

        br.close();

    } catch (Exception e) {
        Log.d("Exception while downloading url", e.toString());
    } finally {
        iStream.close();
        urlConnection.disconnect();
    }
    return data;
}

private String getPlacesUrl(String qry) {
        try {
            qry = "input=" + URLEncoder.encode(qry, "utf-8");
        } catch (UnsupportedEncodingException e1) {
            e1.printStackTrace();
        }

        // Sensor enabled
        String sensor = "sensor=false";


        // place type to be searched
        String types = "types=geocode";

        // Building the parameters to the web service
        String parameters = qry + "&" + types + "&" + sensor + "&" + mKey;

        // Output format
        String output = "json";


        // Building the url to the web service
        String url = "https://maps.googleapis.com/maps/api/place/autocomplete/" + output + "?" + parameters;

        return url;
    }

我已经在谷歌游戏机中注册了我的系统的应用程序包和SHA1。调用getPlaceUrl()方法后我得到的网址就是这种类型：

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=b&types=geocode&sensor=false&key=API_KEY

请帮我解决问题。

我遇到了一个几乎相同的问题。我的logcat如下：

javax.net.ssl.SSLHandshakeException：javax.net.ssl.SSLProtocolException： SSL握手中止：ssl = 0x60b486b8：SSL库失败，通常是协议错误 SSL例程：SSL23_GET_SERVER_HELLO：tlsv1警告不适当的回退（外部/ openssl / ssl / s23_clnt.c：744 0x5ea50d74：0x00000000）

最后，我找到了一个解决方案来修改httpURLConnection.setHostnameVerifier HostnameVerifier验证返回值从false到true，但我不知道根本原因。有人可以提供提示吗？
