How do I fix: No view found for id 0x7f0d00aa?

Question

I've seen people with the same issue and they said that there is something wrong with the .replace() and the way I've constructed the way the fragment and container are written using the: fragmentManager.beginTransaction().replace (R.id.container, new Fragment()).commit(); And that I must do it some other way, which I implemented into my code but I still got the Error. ERROR:

No view found for id 0x7f0d00aa (mcshreker.pocketmath:id/content_main_container)

check if content_main_container is defined in your activity_main layout
