Android Question Autostart service

Good day!
I have an android device named G6818, on it there is an android 5.1. I made a small autostart program, works well.
I had another device (also android 5.1) what was a TV box. I changed the launcher, so it looks like as a normal android, works well. But if I install the previous autostart program, it doesn't start at boot at all. I can run even by hand, but doesn't run at boot. I searched the internet and found some other native java programs for this purpose. They works manually, but not autostart. I tried my older kiosk program, what worked other types phones also, but here not as autostart.
I searched all of settings of the device maybe I find some good option, but nothing I found.
Can I have some hope to solve this problem? Where can I search for solution?
