I have a method that detects call state and sends it to DB, but only when activity in foreground. How can i continue method to work when app is in backgound? How and what should i change so it will run when app goes to background?

Here i call method in onCreate() of MainActivity:

callStateListener = new PhoneStateListener() {

            public void onCallStateChanged(final int state, String incomingNumber) {



                switch (state){

                    case TelephonyManager.CALL_STATE_IDLE:

                        Log.i(TAG, "onCallStateChanged: IDLE = "+state);

                        if (token!=null) {

                            updateState(token, String.valueOf(state));

                        }else {

                            Log.i(TAG, "onCallStateChanged: ERROR");

                        }

                        break;



                    case TelephonyManager.CALL_STATE_RINGING:

                        Log.i(TAG, "onCallStateChanged: RING = "+state);

                        if (token!=null) {

                            updateState(token, String.valueOf(state));

                        }

                        break;

                    case TelephonyManager.CALL_STATE_OFFHOOK:

                        Log.i(TAG, "onCallStateChanged: CALL = "+state);

                        if (token!=null) {

                            updateState(token, String.valueOf(state));

                        }

                        break;

                }

            }

        };

This is method:

private void updateState(String token, String state) {

        Log.i(TAG, "updateState: state"+state);

        OkHttpClient client = new OkHttpClient();

        RequestBody body = new FormBody.Builder()

                .add("token", token)

                .add("state", state)

                .build();



        Request request = new Request.Builder()

                .url("http://update.php")

                .post(body)

                .build();



        client.newCall(request).enqueue(new Callback() {

            @Override

            public void onFailure(Call call, IOException e) {

                Log.d("OkHttp", call.toString());

            }



            @Override

            public void onResponse(Call call, Response response) throws IOException {

                if (response.isSuccessful()) {

                    String responseStr = response.body().string();

                    Log.d("OkHttp", responseStr);

                }

            }

        });

    }
