could'nt Get Session data through api request

i am using api/session to create a new session.
but i coudnt get the session data again when i use api/session GET request.
getting below error
java.io.FileNotFoundException: http://demo.traccar.org/api/session

It means that you are not using session cookie.

Hi Anton,
this time iam getting 406 status code on post session when using requestProperty "application/x-www-form-urlencoded".
what else iam missing

I would recommend to compare your requests with what official web app sends.

please check my request parameters
I am getting 400

String emailid = email.getText().toString().trim();
String pwd = password.getText().toString().trim();
URL url = new URL(http://demo.traccar.org/api/session);

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.addRequestProperty( "Content-type", "application/x-www-form-urlencoded; charset=UTF-8");    
connection.addRequestProperty( "Access-Control-Allow-Origin", "*");
connection.addRequestProperty("X-Requested-With", "XMLHttpRequest");
connection.addRequestProperty("Connection", "keep-alive");
connection.setDoOutput(true);
connection.setDoInput(true);
connection.connect();
JSONObject jsonParam = new JSONObject();
jsonParam.put("email", emailid);
jsonParam.put("password", pwd);
DataOutputStream os = new DataOutputStream(connection.getOutputStream());
os.writeBytes(jsonParam.toString());
os.flush();
final int httpResponseCode = connection.getResponseCode();
if(httpResponseCode==200) {

    startActivity(new Intent(getApplicationContext(), MainActivity.class));
}
else
{
    runOnUiThread(new Runnable()
    {
        public void run()
        {
            Toast.makeText(getApplicationContext(),httpResponseCode+"",Toast.LENGTH_SHORT).show();

        }
    });
}

Why are you sending JSON? I would recommend you to carefully read API documentation. Also, if it doesn't work, compare your request with official web app.

yes now it is working with form data.
thanks.

hi anton,

can i reset a specific users password using PUT /users/{id}
do i need admin access for that too?
and do i need to send the whole user model to update any single value?

one more thing i am getting the user data using session Api

User can update its own password. Admin can update any user password. You need to send full model.

I am getting 400.
I tried to compare my request with offical web app but i coudn't find them in web app.
When trying to reset password no request is generated in official web app. Where can i see them.
below is what iam sending but getting 400 error. Am i doing anything wrong or missing any parameters.

URL url = new URL(http://demo.traccar.org/api/users/"LoginActivity.userId");

final String basicAuth = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);

                        = (HttpURLConnection) url.openConnection();
                connection.setRequestMethod("PUT");
                connection.setRequestProperty("Authorization", basicAuth);
                connection.setRequestProperty("Content-Type", "application/json");
                connection.setDoOutput(true);
                connection.connect();
                JSONObject jsonParam = new JSONObject();
                jsonParam.put("id", LoginActivity.userId);

                out.write(jsonParam.toString());
                out.flush();
                out.close();
                connection.getInputStream();

                int code = connection.getResponseCode();
                Log.d("tesing", "I." + code);
                if (code == 200) {
                    runOnUiThread(new Runnable() {
                        public void run() {
                            Toast.makeText(getApplicationContext(), "password changed", Toast.LENGTH_SHORT).show();
                        }
                    });
                }

You can check requests in the browser developer console.
