access laravel app from android app with csrf token

If you don't want to disable CSRF tokens, then you will need to retrieve the CSRF in one request, then pass the retrieved token along with your POST request.

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();

// Get the CSRF token
httpClient.execute(new HttpGet("http://www.yoursite.com/"));
CookieStore cookieStore = httpClient.getCookieStore();
List <Cookie> cookies =  cookieStore.getCookies();
for (Cookie cookie: cookies) {
    if (cookie.getName().equals("XSRF-TOKEN")) {
        CSRFTOKEN = cookie.getValue();
    }
}

// Access POST route using CSRFTOKEN
HttpPost httppost = new HttpPost("http://www.yoursite.com/your-post-route");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("_token", CSRFTOKEN));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "Hello!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
