Unit Testing Location Service

Question

I\'ve got a location tracking service that I\'m trying to unit test. I\'m trying to use the locationManager.addTestProvider and setTestProviderLocation methods to achieve this.

Answer 1

I was able to get @ingsaurabh's example working in a unit test after making the following modifications:

import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.net.Socket;
import java.net.UnknownHostException;

public final class TestLocationProvider {
    static void sendLocation(double latitude, double longitude) {
        try {
            Socket socket = new Socket("10.0.2.2", 5554); // usually 5554
            socket.setKeepAlive(true);
            String str = "geo fix " + longitude + " " + latitude ;
            Writer w = new OutputStreamWriter(socket.getOutputStream());
            w.write(str + "\r\n");
            w.flush();
        }
        catch (UnknownHostException e) {
            throw new RuntimeException(e);
        }
        catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

The important detail is the IP address. The emulator does not recognize 'localhost' as a valid hostname.
