我开发了一个使用 C# Web 服务的 android 应用程序。我已经使用 IIS 服务器发布了 Web 服务。现在我想将我的应用程序安装到 Android 设备并将其连接到在 IIS 服务器上运行的 WCF REST 服务。
我应该采取哪些步骤来实现这一目标？
到目前为止，我已经使用了下面提到的方法。但是有一些错误:(帮我修复它们！
public String ServiceCallMethod()
{
//int x1 = 262, x2 = 525, y1 = 100, y2 = 390;
String url = "http://192.168.43.73:85/PathService/PathService.svc/FindPath/"+x1+","+y1+"/"+x2+","+y2+"";
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpGet httpget = new HttpGet(url);
// Execute the request
HttpResponse response;
try {
response = httpclient.execute(httpget);
// Examine the response status
Log.i("Praeda",response.getStatusLine().toString());
// Get hold of the response entity
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
String result= convertStreamToString(instream); // returns error when i debug :(its supposed to return an point array list like this..
//Response - {"FindPathResult":[{"x":262,"y":165},{"x":346,"y":165},{"x":420,"y":165},{"x":473,"y":165},{"x":473,"y":240},{"x":473,"y":277},{"x":473,"y":320},{"x":473,"y":390},{"x":525,"y":390}]}
//Instead it returns this
