I think, you can write a Service something similar to the below one (This will do your task for every 5 minutes) and start the Service from the BroadcastReceiver which listens to BOOT_COMPLETED state.

public class YourService extends IntentService {

    public YourService() {
        super("YourService");
    }

    public YourService(String name) {
        super(name);
    }

    private static Timer timer = new Timer();

    private class mainTask extends TimerTask {
        public void run() {
            // TASK WHATEVER YOU WANT TO DO 
        }
    }

    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        timer.scheduleAtFixedRate(new mainTask(), 0, 300000);  // 5 minutes
    }
}
