Spring MVC returns 405 for api call made from my android client - spring-mvc

Question

I have an android app which is making api requests to my server running Spring MVC. The RestController works fine when I make a request from the browser but it responds with 404 when I am making requests from android. Not sure why
Here is code snippet from Android app making requests
public class AsyncFetch extends AsyncTask<Pair<String, String>, String, String> {
public ProgressDialog pdLoading;
private HttpURLConnection conn;
private String urlStr;
private String requestMethod = "GET";
public AsyncFetch(String endpoint, Context ctx)
{
pdLoading = new ProgressDialog(ctx);
Properties reader = PropertiesReader.getInstance().getProperties(ctx, "app.properties");
String host = reader.getProperty("host", "10.0.2.2");
String port = reader.getProperty("port", "8080");
String protocol = reader.getProperty("protocol", "http");
String context = reader.getProperty("context", "");
this.urlStr = protocol+"://"+host+":"+port+context+endpoint;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("\tLoading...");
pdLoading.setCancelable(false);
pdLoading.show();
}
#Override
protected String doInBackground(Pair<String, String>... params) {
URL url;
try {
url = new URL(urlStr);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return e.toString();
}
try {
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(READ_TIMEOUT);
conn.setConnectTimeout(CONNECTION_TIMEOUT);
conn.setRequestMethod(requestMethod);
conn.setDoOutput(true);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
return e1.toString();
}
try {
int response_code = conn.getResponseCode();
// Check if successful connection made`enter code here`
if (response_code == HttpURLConnection.HTTP_OK) {
// Read data sent from server
InputStream input = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder result = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
result.append(line);
}
// Pass data to onPostExecute method
return (result.toString());
} else {
return ("unsuccessful");
}
} catch (IOException e) {
e.printStackTrace();
return e.toString();
} finally {
conn.disconnect();
}
}
Spring MVC Controller
#RestController
public class ApiController {
#RequestMapping(value = "homefeed", method=RequestMethod.GET)
public String homefeed(#RequestParam(value="userId", required = false) Integer id, #RequestParam(value="search", required = false) String search, #RequestParam(value="page", required = false, defaultValue = "0") Integer page) { ... }
}
localhost:8080/api/homefeed -- works
127.0.0.1:8080/api/homefeed -- works
My Public IP:8080/api/homefeed -- does not works
10.0.2.2:8080/api/homefeed -- android emulator to localhost -- does not work
10.0.2.2:8080/Some resource other than the api endpoint -- works
Any help is highly appreciable, have wasted quiet some time in debugging.
