如何在没有gps

Question

我希望使用GsmCellLocation来获取经度和纬度。我得到了CID，LAC，MCC和MNC。但是当试图通过使用

来获得经度和纬度时

urlString = "http://www.google.com/glm/mmap"

它给我一个openHttpConnection错误。我尝试过很多教程，但结果相同。这是我的另一个教程中获取long / lat的代码。

private Boolean RqsLocation(int cid, int lac) {
    Boolean result = false;
    String urlmmap = "http://www.google.com/glm/mmap";
    try {
        URL url = new URL(urlmmap);
        URLConnection conn = url.openConnection();
        HttpURLConnection httpConn = (HttpURLConnection) conn;
        httpConn.setRequestMethod("POST");
        httpConn.setDoOutput(true);
        httpConn.setDoInput(true);
        httpConn.connect();

        OutputStream outputStream = httpConn.getOutputStream();
        WriteData(outputStream, cid, lac); 
        InputStream inputStream = httpConn.getInputStream();
        DataInputStream dataInputStream = new DataInputStream(inputStream);

        dataInputStream.readShort();
        dataInputStream.readByte();
        int code = dataInputStream.readInt();
        if (code == 0) {
            myLatitude = dataInputStream.readInt();

            System.out.println("The lattitude value is  " + myLatitude);
            myLongitude = dataInputStream.readInt();
            System.out.println("The lattitude value is  " + myLongitude);
            result = true;
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return result;
}

我已在清单文件中授予权限。

这个问题之前已经提出过，但我没有得到任何答案。

如果没有GPS，您还可以使用Network_Provider获取纬度和经度。

.shrink a {
    line-height: <whatever>;
}
