i have a django server but the app crash in the android emulator, why?

it is the code:

final TextView t = findViewById(R.id.textView3);
    RequestQueue queue = Volley.newRequestQueue(this);
    String url = "http://10.0.2.2:8000/";
    StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    // Display the first 500 characters of the response string.
                    t.setText("Response is: "+ response.substring(0,500));
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            t.setText("That didn't work!");
        }
    });

  • Please post the logcat. You need to tell the exception that is thrown and not catched. And which statement causes the crash. – greenapps May 31 '18 at 10:54

If the server is running on localhost and app on emulator, then you have to give the other IP as BaseUrl in app.

steps: -> Open terminal, and type ifconfig(on mac os) -> Copy the inet IP address which is shown in en0, and set that as BaseUrl in the app

Possible duplicate How do you connect localhost in the Android emulator?

In case Genymotion then try 10.0.3.2

Use your computers actual IP address! replace 10.0.2.2 with your systems actual IP,check java.net.ConnectException: failed to connect to /10.0.0.2 (port 80): connect failed: ETIMEDOUT (Connection timed out)
