How to keep android application staying alive

Question

I have an application which is using for performance testing. However, this application always be kill in the background in about 5 min later. I want to know how to let it stay alive.(In API 23)

I have tried startForeground(), but it seems didn't work. I logout the oom_adj and oom_score_adj and get the result 3 and 200. Did it do some effect?

Use below

       Intent intent = new Intent();
        ComponentName componentName = new ComponentName(getPackageName(), <Your IntentService>.class.getName());
        // Start the service, keeping the device awake 
        try {
            startWakefulService(getApplicationContext(), intent.setComponent(componentName));
        } catch (Exception e) {

        }
