foreground service without notification

Question

I want to start a foreground service that doesn't show notification, apps like instagram, telegram, zapya, ... have a foreground service and they show no notifications. I have tested ways like answers here, but android shows a notification that yourAppName is running. I want to know how is that possible to have a foreground service with no notification or warning from OS?

Answer 1

How to do it

Here's an up-to-date technique to make it work on all Android versions:

• When the app is running on an Android version prior to 7.1, use this technique.
• When the app is running on Android 7.1 or higher, use this technique.

I know this involves more work than you might like, but it does work, in my experience.
