How to quit or relaunch an android app when user is not interacting with app

Question

i want to update a table in my app database which is only possible when i relaunch the app. So, is it possible to quit or relaunch the android app programmatically, after a certain interval of time when user is not interacting with app or user has put the app in back ground.

Why do you need to relaunch app to update DB? Any specific reason? — Aradhna, May 23 '16 at 05:51
When you say you want to update a DB, do you mean update a column, or you mean add a column/change a column name/etc...? Updating a field WITHIN a column of a table doesn't require a restart. However, a change to the table name, etc... does require a restart,etc... and you will also need to increment the DB version I believe. — ngoctranfire, May 23 '16 at 06:01
because on relaunch of the app, user has to go through login process where i am checking the user status on my server wether it is activated or deactivated then i saved/update it in my database. — sunil kushwah, May 23 '16 at 06:11

just extends this base activty instead of AppCompatActivity

public class BaseAppCompactActivity extends AppCompatActivity {
       //activity restart this timeout
        public static final long DISCONNECT_TIMEOUT = 14400000; // 5 min = 5 * 60 * 1000 ms


        private Handler disconnectHandler = new CustomHandler();

        private Runnable disconnectCallback = new Runnable() {
            @Override
            public void run() {
                // Perform any required operation on disconnect
                finishAffinity();
            }
        };

        public void resetDisconnectTimer(){
            disconnectHandler.removeCallbacks(disconnectCallback);
            disconnectHandler.postDelayed(disconnectCallback, DISCONNECT_TIMEOUT);
        }

        public void stopDisconnectTimer(){
            disconnectHandler.removeCallbacks(disconnectCallback);
        }

        @Override
        public void onUserInteraction(){
            resetDisconnectTimer();
        }

        @Override
        public void onResume() {
            System.out.println("Base Activity Resume called");
            super.onResume();
            resetDisconnectTimer();
        }

        @Override
        public void onStop() {
            System.out.println("Base Activity Stop called");
            super.onStop();
            stopDisconnectTimer();
        }
        static class CustomHandler extends Handler {
            public void handleMessage(Message msg) {
            }
        }

        @Override
        public void onBackPressed() {
            super.onBackPressed();
        }
    }
